Energy Systems Engineer Career Training Guide

Question: What scientific or engineering major would be best for a career in developing solar energy systems? I don't really have a clear idea of what development of solar energy technology would be like. for ex. If that would require research etc.

Answer: Engineering of some form, probably electrical. Firms will also work with physicists. I finished my Physics BSc last year and am now researching solar power for a masters. Physics based work is more 'upstream', I'm working at the research & design stage. An engineer would more likely work further 'downstream', eg on panel installation etc. Most power companies (eg in the UK: Atkins, E.ON, Wind Prospect, nPower) will take physics, engineering, chemistry or maths graduates.

Question: If I want to go in the energy sector,which branch should I opt for-mechanical or electrical engineering? Later on I wish to pursue M-Tech in Energy Systems and Engineering.Though I will be eligible after B-Tech in both the branches,which one should I prefer?Power generation is a field which fascinates me the most.

Answer: Mechanical engineering will give you a better background for the energy sector than electrical engineering. Power generation is highly mechanical on the thermal and fluids engineering side. Electrical will not touch on thermodynamics which is key to understanding power plants. In that sense, chemical would be better than electrical for that path.

Question: How does the Kinetic Energy Recovery System in F1 cars work.? The only way I know how to stre Kinetic energy is in a Flywheel.Are there any Engineers out there who know it is achieved in these cars?

Answer: KERS(Kinetic Energy Recovery System) is a system whereby the goal is to store the energy produced under braking in a reservoir (either batteries or flywheel) in order to release it under acceleration. The 2009 technical regulations state that KERS should not deliver power in excess of 60kW, which is equivalent to around 80 horsepower, when the driver presses a button on the steering wheel. He cannot use more than 400kJ per lap.

Question: What did I do wrong with this potential energy problem? Question Details: A 59 kg engineer leaves her office on the 33rd floor of a skyscraper and takes an elevator up to the 59th floor. Later she descends to street level. The engineer takes the zero of potential energy at street level and the distance from one floor to the next is 3.5 m. The question is: What is the engineer's potential energy in her office? These are my answers and the system rejected them all: 66782 64758 68805 67383 What am I doing wrong!

Answer: if her office is on the 33rd floor, she only has to rise 32 floors 59 * 9.81 * 32 * 3.5 64824.5 J

Question: Electrical engineering - energy of the following discrete sequence and samll questions Can anyone help me with the working for the following problems or just one of them. Coould you show the working so i know how the answer is obtained, thanks. Calculate the energy of the discrete sequence, x[n] = {0,−1, 0, 1, 2}: Calculate the power in the signal x(t) = 3 sin(5t) Calculate the output, y[n], when the sequence x[n] = {1, 0, 1, 1}, is input to a linear time-invariant (LTI) system that has an impulse response, h[n] = {1, 2, 1}: If an 8 kHz sinewave is sampled at 12 kHz what is lowest (positive) frequency present in the sampled signal? Regarding Fourier representations which of the following is FALSE: (a) if the time domain is periodic then the frequency domain is discrete and vice versa, (b) linear discrete-time convolution can be efficiently calculated using the periodic convolution property of the Discrete Fourier Transform, (c) the frequency response of a stable, continuous-time LTI system is given by the Fourier Transform of its impulse response, (d) the continuous- and discrete-time Fourier series are not applicable to LTI systems analysis because of Gibbs’ phenomenon, (e) if the time domain is continuous then the frequency domain is non-periodic and vice versa.

Answer: The energy of a signal, in this case is the sum of the squares of its components. So your answer would be: E = 0^2 + (-1)^2 + 0^2 + 1^2 + 2^2 = 4. The power, or normalized average power, is defined as the Lim(T->Inf) Integral(-T/2,T/2, (3 sin(5t))^2 dt). You should be able to compute that in Mathematica, Maple, or HP or TI graphing calculator. The easiest way to determine y[n] from x[n] and h[n] is through convolution. The equation is (pardon the notation): Sum(k=-Inf, k=Inf, x[k] h[n-k]) Here you 'reverse' one of the sequences, start with a k that's at the edge of the given sequence and compute the sum of their multiples. This can be tricky at first, but you should get: { (1*1+0*0+0*1+0*1), (2*1+1*0+0*1+0*1), (1*1+2*0+1*1+0*1), (0*1+1*0+2*1+1*1), (0*1+0*0+1*1+2*1), (0*1+0*0+0*1+1*1) } which gives you: {1, 2, 2, 3, 3, 1}. Notice that the x[n] sequence is intact and the h[n] sequence is "dragged" through it. h[n] would be reversed in order, but it's a palindrome, so it looks the same. Nyquist theorem states that a sampled signal can only be reconstructed to a maximum frequency of half its sampling rate. A sinusoid sampled at 12kHz can only accurately describe a maximum 6 kHz signal. Since harmonics exist, the lowest positive frequency will be 4 kHz. Regarding Fourier representations: (d) is obviously false, because Gibbs phenomenon is accurately modeled by differential equations and any book on Fourier analysis shows how it applies directly to analysis of continuous- and discrete-time systems. (a) is misleading, because it shouldn't be "discrete" but should be an impulse. The frequency domain is still continuous, but contains two impulses (at the frequency of the periodic signal and the negative frequency as well).

Question: Engineers - is it feasible to use solar energy to power a system that converts corn products to ethanol? One of the major complaints about ethanol is that there's little, if any, net gain in energy. Is the state of the science sufficiently advanced to allow solar power to be the primary energy supply?

Answer: I would like to say yes but at this point I would have to say no. I worked at an ethanol pilot plant and anyone in the industry can tell you to break down starch in the corn you need what they call a jet cooker. This uses high pressure steam at appx 400-600F. There is no way in hell solar panels could heat water to this temperature effeciently and consistently. Plus a lot of ethanol plants run 24 hours a day and that right there pretty much shoots that plan in the ass. A good thought though. Ethanol will become more effecient once the enzyme industry catches up and can CHEAPLY use switchgrass as a fuel source.

Question: I need a diagram for a system to collect the energy of a lightning bolt, utilizing capacitor(s) for storage.? Please only serious engineering responses. Also, not only a system to capture and store this source of power, but also the engineering methods which may be needed to tap the energy once captured.

Answer: lightning bolts have voltages in the millions of volts. You need to buy or build a large value capacitor with a voltage rating this high. I don't think they are commercially available, so you have to design and construct your own. They need to be very high in capacitance to hold a significant amount of energy, perhaps 500 farads. I have no idea of how to design such a cap, I don't think it is possible. You need to locate this on a mountaintop or other area where there are lots of strikes. Next problem is a way to convert the several million volt charge on the cap to a lower voltage that can be converted into useful power, and this I don't know how to do either. I don't think it is possible with present technology. You design and build all of this and somehow haul it up to a mountain and wait. If you get a lightning strike, you perhaps can get a charge of 500MC at 1MV in your 500 farad capacitor. This translates to an energy of E = ½CV² or 1E15 Joules. A large wind turbine generates 5 MW, so 1E15 J is the equivalent of the wind turbine's output for 2E8 seconds or 6 years. So this is a lot of power, if my numbers are even close to correct.

Question: Energy, water and polution issues are all very important so why not use good engineering to fix them? All the polution generated by humans is a result of poor engineering and good engineering can eliminate the problems related to polution at very little cost. Oil and water can be produced in abundance if good engineering is applied to constructing the systems neede to dothe jod. So, why not just use good engineering and fix all these problems rather than continuing doing stupid studies about how bad the problems are. We all know this.

Answer: Maybe the problem is a lack of good engineers that are being turned out by the American educational system. But I agree. To much talk/studies. And not enough action.

Question: In engineering, can you reach a level of expertise where you can freelance and be successful? Or you're the guy in the company no one can do without and are given the liberty to command hours through flex time unless if something big is due? I'm referring to mainly electrical engineering in the areas of RF/networks or green energy systems.

Answer: There are many engineers who work as consultants. In addition to having a great deal of knowledge and experience they also have to be prepared to work when the client needs them. It usually takes a while to build up a reputation and client list but once you have one, your have to provide service when needed or the clients will go elsewhere.

Question: What is expected from a research paper submitted by an undergrad student? Does it have to explore new solutions or explain existing ones? Also, among the following, which is more interesting? ( i am studying electronics and communication engineering) Artificial Intelligence Bio-Medical Instrumentation Wind Energy and Other Non-conventional Energy Systems Multimedia Compression Techniques

Answer: What you're submitting it for will make a lot of difference. If it's for a class or perhaps even an undergrad paper competition, the rules will be a lot different than if you're submitting it for journal publication or presentation at a professional-world techincal conference. I'd imagine that, at your level, it's probably more about reviewing what information is out there unless you're writing about some actual research you've worked on in school. Most of the "new solutions" kinds of things are what grad students/professors/professional industry researchers deal with. Perhaps if you'd be doing some smaller undergrad research project with one of your professors or working with a grad student on a piece of their research, you'd have some of that to share with the world -- but you'd also probably be getting input on both the project and writing it up from above as well and likely then also wouldn't be the sole author. As far as what's most interesting, that's a hard one for any of us to tell you. I actually think they all sound cool, but would get lost quickly trying to research those as they're definitely not my discipline. I'd imagine there's a decent body of work out there for any of those topics, so I'd just pick one you wouldn't mind looking at more closely and go with it.

Question: Would a degree in Chemistry or Chemical Engineering be better suited? I am ultimately interested in fuel technology and implementing new energy systems, such as fuel cells. To do this, would a degree in Chemistry or Chemical Engineering be better? Also, does chemical engineering require a lot of physics?And is it really just calculating pressures in pipes, as i've been told?Hope not... Thanks!

Answer: Chemical Engineering opens up a lot more doors than a standard Chemistry degree does. Go with Chemical Engineering, unless you plan to become a Professor and pursue teaching and pure research. If THAT is the case then choose the Chemistry degree.

Question: Companies dealing with energy? Hi, I am a masters student in Columbia University, specializing in energy based systems. I have a mechanical Engineering background. I have started looking for a job in related areas. Can you suggest me companies in the US who would be able to use my skills - areas related to renewable energy/ fluid mechanics, CFD / heat transfer.. I know that there are many companies that deal with such areas.. But I am right now collecting the names of such companies, so that I can look them up and apply to them in case I am interested in the stuff they do. (Basically, I'm short of names :).. Hope you can help me out. Thanks!

Answer: Westinghouse Electric Company's nuclear side of things is hiring mechanical engineers. There's a lot of fluids, heat transfer, and thermodynamics involved in the plant systems. The nuclear industry in general is actually doing rather well, but Westinghouse is a good place to work.

Question: Electrical Engineering: Tennessee Technological University or University of Tennessee Knoxville? I want to do something along the lines of Renewable energy systems. Which College would be better money/education wise? Btw, i Live in Cookeville right next to TTU. And i got a 31 on my act, take all AP classes and a 3.8 unweighted gpa. I want to go to TTU but i dont know if the education will be as good as UTK.

Answer: Certainly great schools attract great professors, but for that matter great teachers can be at any school. And, with something as challenging as an engineering field, a lot of the quality of your education will be in how much time and effort you put toward your degree. My high school stats were similar to your own, but college was a real challenge. This is mainly due to the fact that high school was fairly simple for me and I had not yet needed to study, certainly not to the degree that was required for my college level courses. I struggled for several semesters to get my system down. It was a combination of asking for help and taking time to read more slowly, take notes on what I was reading and work example problems in addition to homework. Asking for help was a difficult thing for me to do, I didn't like asking for help, it felt like "cheating". Most everyone else seemed to be in study groups and homework groups, I just felt like I needed to do it all on my own, but in time I learned the value of using these types of groups on occasions to help with difficult topics. Anyway, all that to say that either school will likely be great for your education. Even if the professor is not exceptional you can make up the difference with your own effort in many cases. I would focus on things that you have less control over, such as finances. If your schooling will be paid for out of your own pocket, or if you parents have limited funding I would be looking seriously at the total costs (tuition, rent, food, books, travel from school to home, etc.) One last comment, of those that have the opportunity and desire to attend college most people leave high school and head directly to their university of choice. Remember that it is an option, and not a detriment to your career, to work for a year or two before going to school. It might give you an opportunity to work in the renewable energy industry to see which aspects you like and to get some "real world" experience. Some of these realities, including financial responsibility, can make your college experience more rich in the sense that you know how important each course is and how they can propel you in your future career. One last thing to check, if you decided to start with one school and switch to another you will be very interested to know which credits will transfer. You might want to call the admissions office of each school and see if they accept all the courses from the other college, one may be flexible and the other may not. It would give you more options if you wanted or needed to change schools in the future.

Question: pls a exactly explanation about the system of the bus to operates the air conditioner? pls engineer, technicia pls a exactly explanation about the system of the bus to operates the air conditioner? pls engineer, technician, all people around the world explain how its work why? what? if operates at dc?why or it operates at ac and and why?what is the best and explanation for my question about the solar air conditioner operates to all busses & how much energy charges? how much batteries have? pls help me for answering my question...thank you!!!! god bless you all!

Answer: A normal bus will have an Air Conditioning (AC) system that runs a compressor that is driven by a belt from the motor. The belt runs the compressor motor, which provides the compression in the AC cycle. The condenser is where the refrigerant condenses, absorbing heat from the air, thus cooling the air to a comfortable level.

Answer: let's look at a typical parking voucher dispenser, as seen in Toronto. its back-lit, LCD screen displays time of day and amount of money; and it accepts coins or cards, and prints vouchers. during the day, this thing works on photovoltaic cells. but it keeps working until well-after dark, (up to 9 or 11pm when parking becomes free, and still keeps its clock running until morning.) To do this, it must store excess energy from the photovoltaic cells during daylight, and draw that later. There are two strategies it might use: capacitors, or rechargeable battery. which would you use, and why?

Question: I wana do something, but i have no clear picture.? I am engineer working as Project engineer and doing MS in Energy system. but i m not ssatisfied

Answer: It is best to pick something that fits your personality and contributes toward goals that you think are important. Write out your personal goals. Consider your values and set your priorities based on what YOU value most. Once you have goals, you need to develop a plan. Decide what steps need to be taken, and what resources you need. Most people fail to plan or are unwilling to leave their comfort zone and commit resources where they have to do something unfamiliar where there is some risk of failure. Attitude is important. It does not matter if you think you can, or you think you can not, more time than not, you will be right.

Question: engineering systems? a steel bar with a diameter of 22.5mm diameter has a mass of 0.75kg and an effective length of 350mm is heated from 18oc to 195oc calculate: (i) the heat energy recieved by the bar (ii) the final length of the rod after heating the specific heat capacity of is 460j/kgK and its linear expansivity is 12 x 10-6/K

Answer: (i) the heat energy recieved by the bar = 1.0704263527656 * 10^9 joules Heat added = specific heat x mass x (tfinal - tinitial) with specific heat c = 8063.4753504 joule/gm°C mass = 750 grams initial temperature = 18°C final temperature = 195°C (ii) the final length of the rod after heating = 350 + 2.124E-3mm linear expansivity is 12 x 10-6/K(Part of Youngs modulus for steel)

Question: Could I work for the Airforce or Department of Defense? I recently saw an article describing a weapon I thought up over ten years ago that has been developed, called an electrolaser, I never pursued the idea myself,and never really explained the idea to anyone, but by coincidence or not, they did it.Does the government need inventors,or do they have plenty already?If I could work for the military,would I be payed well,or would they just rape me for information?How could I get a type of job wherein I would work with engineers in developing things like missile defense systems and directed energy weapons?

Answer: They are not going to hire you as an engineer without a college degree. But, yes, DoD does hire engineers to design weapons and equipment.

Question: Are you promoting "alternative energy" or God's energy ? God's energy is nuclear power ! He uses nuclear fusion to heat all the stars, and thus our sun which heats well and safely our solar system. We too should engineer this same nuclear fusion process to provide unlimited energy worldwide for homes, schools, factories, transportation, etc. This should now be a high priority to solve and eliminate the energy crisis. For the time being, many advanced nations are using clean and safe nuclear fission power plants. "The sun is a natural fusion reactor."; and this article in Wikipedia, link below, explains why fusion power it is even safer than reliable, proven, fission power.There is also much more there of interest. Please read this basic info before replying. http://en.wikipedia.org/wiki/Fusion_power Thank you for all sincere answers. Peace and progress in all areas !

Answer: The energy crisis is a result of failed regulatory practices. Part of that failure has been to prohibit the use and development of natural resources such as you mentioned. 2010, clean house.

Question: I want to know where I can find info on Dr. Maria Gherardi, seen on "Extreme Engineering? I was watching City in a Pyramid on Extreme Engineering on the Discovery Channel. She was experimenting with the use of hydrogen obtained from pond scum. She has a lab - I think it is called Energy Systems Lab. I would like to obtain info on her findings and on the lab - contact numbers, etc.

Answer: Maria Lucia Ghirardi - Senior Scientist phone: 303-384-6312 email: maria_ghirardi@nrel.gov At NREL since 1995 Dr. Maria L. Ghirardi is a Senior Scientist at NREL and a Research Associate Professor the Colorado School of Mines in Golden, Colorado. She received her Ph.D. degree in Comparative Biochemistry from the University of California at Berkeley in 1988. Since then, she has been involved in both basic and applied research and has had extensive experience working with photosynthetic organisms. Her work at NREL involves photobiological H2 production and covers metabolic, biochemical, and genetic aspects of algal metabolism.

Question: Wouldn't it be better to spend $250 billion on a New Manhattan Project for clean, sustainable domestic energy? than to dump $700 billion into a failed banking system? Such a program would revitalize American industry, provide thousands of construction and engineering jobs, and provide vast investment potential--all while helping us kick the toxic foreign oil habit. Seems like a win-win-win to me, whereas all the bailout proposal seems to do is get us to tread water for maybe a little longer.

Answer: Great point. But be careful...you might confuse the government with your clear logic and critical thinking. How would it not be beneficial to create jobs and wealth...instead of feeding it to Wall St? I don't know...it seems so obvious to me, yet the gov't just wants to waste my money. Ugh...

Question: What do environmental engineers do? I know they design things like waste/water treatment plants and stuff. But do they also design alternate-energy systems such as wind-turbines and solar-energy sites?

Question: How much would you make if you owned a Military Company? Basically I'm talking about how much would I make if I was owner or part-owner of a military industry featuring all this. Guns, ammunition, missiles, military aircraft, military vehicles, ships, electronic systems, research and development, steel, energy and a private Special Military Corp. My dream is to one day put all of this into one company. i'll be the real-life Tony Stark I want to be a Weapons Engineer when I graduate :)

Answer: You could make a lot of money....problem is, you're going to need a lot, A LOT, of money to start a business like this. That's going to be kind of hard to do these days.

Question: Is it possible to take 2 engineering majors in college? Specifically I want to take Mechanical/Systems (dependent on school) and Electrical Engineering. I already know I'm going into a heavy course load with (hopefully) overlapping classes. The end goal is to have specializations in energy research in graduate/Ph.D. level courses. Any and all advice about this would be very welcome!

Answer: Not if you plan to graduate within 6 years. I strongly suggest you look up the actual courses and see if any of them overlap. At my school, the first year of engineering is the same, no matter the discipline.

Question: Dream-home, What's yours? Dream -houses. [Thread] discussing my/your dream home. Or are you not a dreamer?[/thread] So my dream House in short. 1 - Shell – Garage/Hall Like structure, yes that means no walls. 2 - Walls– However few will be painted all white. 3 - Top of the range home automation system, installed by myself which will control Video, Audio, Heating, Lighting, Security from points all around the house, And also away from home with my Smartphone via the internet and SMS messages. 4 - Garage will be inside the house – Yes that means living with my vehicles. 5 - My Bed to be set in the center of the house – Everything same distance away from bed. 6 - Contents of the house would include, High tech Gaming PC’s, highest speed broadband, LAN capable, all new consoles out at that time, with games to boot. Epic home theater system. Bean bags would replace the traditional sofas and chairs, fully solar /wind powered, with geothermal heating. 7 - Computer hard-drives will hold a fully functional Wikipedia to quench my thirst for knowledge in all fields for use in times of internet outages caused by the dictatorial European regime that will be in place by then. 8 - The traditional Kitchen/bathrooms randomly placed somewhere in the big open room. 9 - I will definitely be a crazy cat man, with a few bichon frise dogs(Don’t Shed),and are cute as they get. And of course that's not covering half the contents you'd usually find in an average house,(Art,phones,shelves (which will be cool), windows (obviously),brand of toilet paper etc etc) I'm 18,in college studying my first year of a computer science and information technology degree. Covering programming,computer systems,electronic engineering,and energy and enviorment informatics. Just thought that might show people where i'm coming from with all these techie ideas. I will definitely be a crazy cat man, with a few bichon frise dogs(Don’t Shed),and are cute as they get.(cough not gay) Well that's the plan. what are yours?

Answer: My dream home is definitely an open concept large roomed home. It would be a glass house and would have a ton of light shining in. I'd have stainless steel appliances and dark cherry wood shiny cabinents. It would have beautiful granite counter tops but one would have a stainless steel top where I could use it as a cutting board and food prep area. I'd have white walls, and white furniture but dark cherry hardwood floors. I would have a huge huge walk-in shower and a jaccuzi bathtub. A huge bathroom. I'd have a huge backyard that would be fully fenced so that my Bichon Frise could play and play and run free in with a second dog that I would get for him to have a friend. :) I would love for it to back out onto a lake or ocean or have a beautiful view of the ocean. It would definitely have solar power! It would be in Paradise!

Question: Is the Honeywell system, used in the Energy sector, linked to SCADA? This relates to Instrumentation/Engineer

Answer: Honeywell systems are SCADA's. They can be linked to other ones through various protocols.

Question: When will our government admit it possesses "zero point energy" technology, which is clean, free, energy? alleges that our military industrial complex has reverse engineered, in covert military projects, extra-terrestrial power systems which could easily solve our energy "crisis." The upshot is that the last 50+ years of oil and nuclear pollution has been unecessary, because we've secretly possessed this technology since the 1950's or so. The Disclosure Project has 400+ witnesses willing to testify against the government in Congressional Hearings, but the political will-power does not yet exist because no one will take this topic seriously, and certainly not the US mainstream media! A 19th century physicist, Nikola Tesla, also made similar discoveries about energy -- and his research is also heavily suppressed because if everyone could run their house, or car, or business from a zero point energy generator then the power companies couldn't hook a meter up to it and charge you for the service. A 1st world standard of living could be sustainable with ZPE.

Answer: If you think about the properties of electromagnetism and electricity itself, and you study up on Teslas ideas, it seems as if there is a whole new area of science waiting to be seen by the mainstream. It is not complicated at all and should be looked into.

Question: Which is the best for a master ? i am at mechanical engineering... suggetions ? 1. Fluid Mechanics and Energy Systems 2. Micro- and Nano-technology 3. Turbulent Flow 4. Environmental Engineering 5. Biomedical Engineering 6. Machine Intelligence and Robotics 7. Materials Processing 8. Mechanical Systems and Controls 9. Automated Design

Answer: Fluid Mechanics and Energy Systems,energy move the world!!!!!!!!!!Always in demand...

Question: How physically strong are plants and trees? Most of us have probably noticed saplings which have pushed themselves through thick tarmac or even cracks in concrete - and not to mention root systems. So, how strong is this vegetation? And could the force be compared to man-made engineering such as hydraulics? Was hydraulics/pneumatics in engineering founded on the pure fact of studying nature? How do plants create such forces in energy? How do they do it? How can this true force and power be measured?

Answer: it depends on the plant / tree

Question: Information and Advice for My Green Future? My Green Future Allright guys... First and formost, I am a college student. Specifically a sophomore civil engineering student. A few years I became fascinated with the idea with going green and especially anything related to renewable energy. (Specifically the various forms of wind and solar) I cannot even begin to explain the passion I have in pursuing a degree that is going to help me with a long successful career with renewable energy. Now I have already talked to quite a few companies asking questions I think that are most beneficial to my cause, but I want to ask people outside of the formal business world and ask for their opinion's as well as other suggestions and alternatives as to what they see as a route or path to success. Who knows, your help may also help others searching for similar questions that I might have. So in advance I would like to extend my appreciation to anyone that can help me out. Thanks alot! Like I said above, I am currently in civil engineering, but the more research I do I keep finding that civil is probably not the type of engineering that is going to best suit me for a engineering career in renewable energy. I have narrowed down my selections to Industrial & Systems and Mechanical Engineering. I would include electrical, but I am at a point where switching and carrying credits over would affect me too much and do more harm than good. Now I already know that mechanical will probably best suit any renewable field but I am also curious where industrial and systems engineering might apply too? Also aside from the business degree aspect what other degrees are being considered that will get someone a job in a renewable field? I was also curious if anyone had some websites or forums or any other places that they would think are beneficial to others and I looking for information regarding the rewable field?

Answer: Going green is a very good idea. and interesting one too because it is sort of new. There are many different types of new available energy sources. I am quite interested in majoring in some kind of Engineering, but not sure which. I think materials engineering is pretty good too. u examine the properties of materials and compare them and experiment with them. who knows, maybe u could create a new cheap energy source! good luck!

Answer: Try getting details at http://care4com.blogspot.com. They'll research for you at very low cost.

Question: Which kinds of scientist should I be? Things I like to do (Order DOES matter) 1. Doing challenging MATH 2. Thinking new ideas in term of PHY/CHEM 3. Studying about Earth's system 4. Finding the explaination of nature 5. Thinking without a purpose 6. Interested topic: Environmental issuses, particle, physical CHEM, energy generation, universe 7. Answering people's questions Should I be a scientist or engineer? Which field should I be specialized, please be specific? The best answer would be the one provides information about research project in that field (which university) and its undergraduate program. Many thanks, it is extremely important to me. Many thanks. PS: Would it be better if I do ''General Science'' in University? But my concern would be it maybe too easy for me. Because my school report card is much higher than its entrance requirement. Also, I am planning to take two years off because I am only 15. What can I do within these two years to achieve my goal in post-secondary endcation? Thanks.

Answer: Columbia University's Fu Foundation of Science and Engineering would be an excellent school for you. You should consider going into chemical engineering. There is a shortage of chemical engineers in the United States and you can really contribute to the environment and the world by studying such a powerful subject.

Question: What is the equivalent of a 2:1 Hons degree from a British University in terms of the American GPA system? I have just received my degree classification, a 2:1 BEng (Hons) in Mechanical Engineering and am wondering what that is under the American system as I may want to do a masters in renewable energy in the US next year or in 2011. P/S I'm aware of the fact that I need to do the GRE exam as well.

Answer: An upper-second class degree is roughly equivalent to 3.3-3.6 on a 4.0 GPA scale. This is according to UCL (University College London). However, you should get an assessment of your academic transcript(s) through a formal evaluation service as there is no rule of thumb in this conversion just like TOEFL to IELTS scores (or vice versa) if you've ever came across them.

Question: What do you think of these conspiracies of AREA 51? The storage, examination, and reverse engineering of crashed alien spacecraft (including material supposedly recovered at Roswell), the study of their occupants (living and dead), and the manufacture of aircraft based on alien technology. Meetings or joint undertakings with extraterrestrials. The development of exotic energy weapons (for SDI applications or otherwise) or means of weather control. The development of time travel and teleportation technology. The development of unusual and exotic propulsion systems related to the Aurora Program. Activities related to a supposed shadowy one world government or the Majestic 12 organization.

Answer: that's the government for you, always hiding there special stuff from everyone else. if they keep it a secret other country's will believe its just a joke

Question: Is there more to electrical engineering than circuits? I'm in my intro circuits course now, and while the analysis of them doesn't bother me too much, building them with those tiny resistors is tedious to me. The same idea in my logic design/digital systems class. I would like the math of EE probably as it's applied calculus. I'm interested in green technology like clean energy systems and also RF technology with stuff like electromagnetics. Admittedly, I haven't take the engineering electromagnetics yet but I liked EM physics, and the primary technology I like is stuff that transmits waves. Either that or big electrical systems. My whole major won't be based on building tiny circuits like that, right?

Answer: yes, only a small subset of EEs actually build circuits, and that group is shrinking. For example, SMD (surface mount devices) are becoming more prevalent, but it requires special training to work with those, so usually it is special technicians who do that. Another trend is towards more and more integration, which means most circuits become just an IC or a group of ICs. Analog design is the remaining area where engineers will work with a soldering iron, and even there, that is perhaps 10% of the time, from my experience. The rest is compute simulation, software, and meetings. .

Question: Any feasibility research on self-replicating, space mining systems? How far off are we technologically speaking before we can send automated robotic miners to the asteroid belt to replicate themselves and harvest minerals therefrom, for the purpose of either 1) building space ports there or storage stations or 2) delivering harvested minerals to other parts of the solar system (Mars, Phobos, Deimos or Europa) to auto-assemble the beginnings of space stations in those places while we wait for our space travel technology to evolve? It seems that a self-replicating mining system would amass great resources in the time required for our safe space travel technology to evolve. By the time we're ready to take a quick little trip to Mars or Jupiter, we could already have vast human-friendly resources (e.g. a space station?) ready and waiting for our instructions for customization. We know the instructions are programmable and executable right now. But what kinds of engineers would be required to connect the harvesting of available energy (e.g. solar, nuclear) to self-replicating units (like nano-tech builders that build other nano-tech builders, using raw materials) so that robotic miners could carry out specific tasks of accumulation and replicate their design in deep space with minimal monitoring? I don't mean sending HUMANS to mine in space.. I mean sending satellites to plant automated miners that can also build more of themselves (self-replicating) So it wouldn't involve sending any human team. That's the whole point of the question.

Answer: The problem is that as this point, space travel for mining purposes is not profitable given that mining on earth is easier and cheaper. Doing research and launching a ship to space is very expensive, and the private sector isn't interested since, so far, there's nothing they really need from other planets that could give them any money. That's why most of the large space programs are usually ran by the governments.

Question: project title? am studying mechanica -energy engineering,am interested in HVAC system design particulaly cooling towers,can anyone suggest me a best title as my final year project?

Answer: "the cool cooling tower" <

Question: Calculate the maximum possible work produced per unit of high-tempeture heat? Ocean Thermal Energy Conversion (OTEC) is a method for producing energy from tempeture differences in the ocean. Calculate the maximum possible work produced per unit of high-tempeture heat, assuming heat is taken into the OTEC system at the water surface (300 K) and waste is rejected below the surface (290 K). This is from my Engineering book and it has no more useful information to give to solve this problem. Any help would greatly be appreciated.

Answer: I'll take a hip shot at this one... Ok, so if you have an ideal engine, if you write out the energy/work equation, then start knocking out terms, you'll end up with Q = W, i.e. your ideal engine will convert 100% of the thermal energy into shaft work. It's been a while since college so I'm used to working in fahrenheit and BTU's, not KJ and Kelvin, but if I remember correctly, (pure) water has a heat capacity of 4.19 KJ/kg C. You're talking a 10degree kelvin change, which is the same as 10 degrees celsius. So, Q = mCp(Ti-To), (Ti-To) = 10 degrees, Cp = 4.19. m is your mass flow rate (Kg/min or hr). So, Q = 41.9 KJ/Kg x m. If you cycle 1000 L/min (1000 Kg/min), you'd generate 41900 KJ/min. The problem with these systems is that the transfer efficiency for thermal engines is typically very poor, plus you'd have to HEAVILY insulate the piping from the surface to the sub-level to prevent energy loss as you bring your "high energy" surface water down. Not to metion that a 10degree gradient a WEAK thermal driving force, and the pumping energy to drive the water deep enough to reach the 10degree gradient is usually more than the energy you would recover with your engine. (Not to mention the sierra club and EPA would jump all over you for thermal pollution of the ocean, aquatic sealife is dependent upon a certain temperature, these systems warm a region of the ocean that's spent millions of years aclimating to a specific water temp and oxygen level).

Question: If you can invent/create something, what will it be? Why am I asking this question? I have a homework assignment that requires a written proposal on either developing or creating a product or just a project to work on. It can be things like plans on developing sustainable energy preservation, longer battery life, enhance the human life quality etc. (technical problem related if possible). Why am I asking you instead of myself? An honest answer will be that most things that I think of are personal ideas that aren’t going to greatly benefit the people. An idea won’t last unless it will help the society and that is something I’d like to work on if possible. So, I want a product or a project that will help the community in the long term. When you are answering the question: 1: Do not worry about silly answers! A lot of things are unpredictable, especially science! A really good example that I really like is the one that my teacher gave in the seminar class. Instant transportation – how amazing it will be if you can be transported from one place to another? My teacher used to dream about that and it’d be really helpful if it was real! Anyways, he told us that scientists are working on cell transportation and they actually succeeded in doing so! We are made of cells… if they can do it to a single cell now… the possibility is unimaginable! 2: When you are thinking about this, I’d like you to think what is missing? What do you want? Credit: If I were to use your idea to write my proposal, I will give proper credit. It will be really cool if it is something that is practical so I can work on :D but even if it is not, it is still cool because like I said previously, don’t let anything stop the imagination! I am intrigued by my teacher’s idea, but it doesn’t make a great connection with my major (which is Computer Systems Engineering). I’d have to work on biology and such if I want to work on that project >< Anyways! Any suggestion will help greatly. Thanks a lot in advance :D

Answer: There are many things that come to mind. -A more practical/effective worldwide transportation system (to travel quickly, this will POSSIBLY bring more unity to the world) -Educational information network (Great variety of info on educational fields available for all for free along with resources need to learn) -Automated goods distribution system -Urban agriculture products -Some sort of program to teach practical skills to people such as mechanics, plumbing, construction. -More interactive media. i.e. feel,smell, taste games or movies.... The possibilities are infinite! Good luck with your assignment!

Question: How does someone break into a new technical field? I've been working in the Biopharma industry (background is Chem Eng.) for about 8 years. Some process development, but most quality control and computer systems administration. I've never particularly passionate about the Biopharma industry, so last year I took 4 Graduate level courses in Solar and Wind energy engineering. Unfortunately, I've had no luck getting any nibbles in what is supposed to be a growing field. Most companies seem to want someone with LEED, CEM or other certifications, but most of those require you to be working in the industry to become certified (bit of a chicken and the egg thing in my mind). Does anyone out there have any advice for how to switch TECHNICAL fields. Has anyone done this? I'm willing to take a bit of a pay hit at first if I have to before I gain some experience, but I prefer not to go back to an entry level salary. Any advice would be most appreciated.

Answer: Networking. Make friends and meet people in the field you want to join. You may have to go back to entry level salary if your skills and knowledge have no real world benefit in the field you want to be in.

Question: Should the Blue Smoke Theory be taught in schools? The Blue Smoke Theory states that electronic components work, not by the motion of charged particles across energy barriers, but by magic blue smoke which is contained in them. While nobody has ever seen an electron, and it is preposterous even to suggest that a hole could ever move anywhere, there have been many observed instances where blue smoke has escaped from an electronic device -- which then ceased to work. Many people in the field of electronics, including the majority of Microsoft-certified systems engineers, are abandoning traditional ideas concerning charged particles in favour of the Blue Smoke theory. Shouldn't both theories be given equal time in the classroom, in order for students to make up their own minds as to which one is better?

Answer: I wondered if this could be related to the old Phlogiston theory.

Answer: First of all, I do not understand about your taking two years off. Many colleges and university do admit exceptional students such as yourself at your age. About some of the freshman and sophomore college courses being too easy for you; you can ask the college that you'll be going to to give your tests on some of those subjects. If you pass them with high grades, you'll be given credits for them and not having to take them in class. That way, you may graduate from college sooner and go on to post graduate education for your master's or doctoral degrees or both. Remember that courses during the first two years of college are very similar for all science students, whether they major in general science or a specific science field such as physics, chemistry or astronomy. So why not just leave it at science and not declaring a more specific field until your junior year? For you, try MIT ( Massachussetts Institute of Technology) or Caltech (California Institute of Technology). They are among the best in science and engineering education.

Question: Shouldn't "clean energy now" be the only serious spiritual question of our age? If religion is about visions .. shouldn't we collectively be visualising this and politically and spiritually demanding it .. We have the engineering minds ... We have MIT graduates every year .. but they go to work for lockheed to build a new unmanned vehicle(predator drone) to deliver destructive weapons systems .. "tactical to practical" has become the mantra of the trickle down of research to the public sector's eventual benefits .. But why not "practical" first .. Oil moguls have much at stake .. so much for them to gain by the petroleum tap slowly going dry .. and the profitable shortages and wars ... The technology is discovered! .. No dirty greenhouse byproducts in burning pure hydrogen from hydrogencell technology .. but terrestially gleaning it from natural gas is a big greenhouse emitter (sorry you who misassume it can be derived from ocean water-you are mistaken).. So where is abundant pure hydrogen to be had? .. In space all around us ... Just need a strong space to start tanking in down .. Shouldn't the priority of Christians, Muslims, Jews, Hindus , Bhuddhists and all others be .. to stop our politicians catering to the oil and arms magnates .. and get us clean energy now! Why can't stepping into space peacefully to harness resources become tghe priorities of our industries rather than weapons production .. and dirty petrochemical burning for an energy consumption we simply will not wean from? re: arewethereyet.. okay .. I wouldn't want to interrupt the happy appocalypse you want to vindicate you .. Upallnite- so I suppose you never heard of Physicists creating a sanctified environs for a particle collision.. well it happens .. they want to help fellow humans .. their unorthodox conceptions of deity I suppose do not live up to the destruction and vindication you want from a god .. very good alnitaka.. and truly on trak .. but pure hydrogen is in space my friend .. and all around us .. Religious folks .. so sorry to upset you .. Isee something that could heal earth's environment .. and prioritizes us out of weapons and war- and towards being custodial to earth just seems so offensive to many of you .. keep "religion" out of clean energy- anbsurd! Thanks JediBaptist and SmoothFlo.. some thoughtful answers are appreciated! Thanks miraclewhip- you rock! can more be said?..yes..????? So far alnitaka has a smooth lead though.. reading im a few times- I feel he may even be affirming that the hydrogen is attainable there in space .. but still- this isn't a chemistry oriented question .. doesn't anyone see the "spirituality" that could be so inherent to this question?.. what is more sacred than the continuation of our planet and life? ... anyone? re phyllis n: admirable honesty .. well for me "the 100th monkey" is a good example about spreading innovative ideas .. Personally I believe engineering minds like "alnitaka" above need to see the potentialities .. secondly because we are what we are "socioeconomically" .. financiers will simply need to see the "capital" potentials of such a transformation, to the point of overwhelming the vested interests that would like to keep it as is to our collective ruin .. Ideas are "contageous" tho, and there is always hope.. however fashionable ansgt and nihilism become(they are a few centuries old now)... hope exists nonetheless ...

Answer: Unfortunately, hydrogen does not exist on this planet, or not at least like oil does. Most of the hydrogen that the Earth ever had escaped because Earth's gravity can't hold it. Almost all the hydrogen on the Earth is in the oceans as part of H2O. It is going to be hard to set up a system of using hydrogen, but it probably can be done. Solar-powered electrolysis plants take the hydrogen out of water. Then the hydrogen can be used as fuel. A problem with this is that hydrogen's molecule is so small that it is hard to find a container to hold it. We may have to weight it down with a bigger molecule, such as carbon atoms, each of which can hold onto 4 hydrogens. But guess what? This is natural gas. We do have a dwindling supply of that, but I suppose electrolysis combined with carbon could produce synthetic natural gas, which is then used as a fuel. We need to do this as we are running out of oil and other fossil fuels. But it is not going to be easy.

Question: Doesn't this beat the aimless tweeting we hear about? Could you think of any more good uses that twitter could be put to? London, September 9 (ANI): A cottage on an English island may have become the most envied house after its owner converted it into one of the most hi-tech homes in the world by connecting it to popular internet messaging service Twitter. IBM head of invention Andy Stanford-Clark installed his home with hundreds of sensors that inform him when his dinner is ready, if someone is at the door or when a mouse has been caught in a trap. The Tudor cottage on the Isle of Wight automatically sends a Tweet or message to the 43-year-old engineer if energy usage level is higher than normal or if he has left a light on or a tap running. The house also alerts about things ranging from the burglar alarm to be relayed by the blogging website. "Monitoring things such as how much power our house is using can give us valuable insights into the cost of various appliances in the home," the Telegraph quoted him as saying at the British Science Festival. "Recently I was out and got a tweet saying water usage was higher than normal. I phoned home and my wife looked out of the window to see the garden hose had been left on. "This can help us take steps to reduce our carbon footprint and reduce energy bills. Mine has dropped by a third in the last year. These systems are also relatively inexpensive to set up - a basic set-up would cost around 150 pounds," he added. Stanford-Clark also said: "It is impossible to know if traps have been triggered without constantly checking. So I developed a Twitter mousetrap which sends me a message when it is triggered." (ANI) http://in.news.yahoo.com/139/20090909/959/tod-the-hi-tech-tudor-cottage-that-twitt.html

Answer: That's sad. Instead of using his brain and turning the water hose off himself he had to have a computer tell him to. Everyone knows leaving water on and things plugged in uses resources. I don't need a computer to tell me that. Just another step down the path to humans dependency on computers.

Question: What is a good thing to do to burn energy while watching TV? I have an extremely busy schedule right now and changed my eating habits to include more vegetables and fruits. I did this for two purposes. 1. I want to lose twenty pounds over the course of a year 2. I wanted to build a strong immune system since I go to a school that does not protect students with doctor excuses to miss school. So basically everyone is going to school sick and in the engineering school alone there have been like 3 cases of Swine flue. I'm not really afraid of H1N1 but I really can't afford to get sick. Teachers don't care if you have an excuse. I have problems sleeping in general but I take medication for it and I had been able to sleep. Now though I have too much energy to sleep of nights. I have a calm down period that I watch TV (usually something like forensic files) to slow down my mind but lately I can't slow down my body. So I just need a way to burn off energy while watching TV at nights. I don't have time to go the gym during the day and its not really safe were I live to go there at night.

Answer: Try lying on the floor on your back and bicycling your legs in the air or do sit ups.
