questions about energy?
i have some school homework for science and it’s really hard can anyone tell me….. how to build a candle operated steam turbine from simple materials Build a simple wind powered generator and build a working model for a solar water heating system using every day materials
does the energy from a power plant originally come from the sun?
At the T. B. Simon power plant, burning coal produces steam in a boiler, the steam flows through turbines, the rotating turbines drive electric generators, the generators deliver alternating current to the transformer station, and the transformers provide emf to the campus electric grid. Thus electric power is available throughout the MSU campus. Therefore the […]
physics problem witrh time rates and combustion!!! HELP!?
a heat engine consists of an oil-fired steam turbine driving an electric power generator with a power output of 120 megawatts. the thermal efficiency of the heat engine is 40 percent. a) determine the time rate at which heat is supplied to the engine. b) if the heat of combustion of oil is 4.4 x […]
Power & Energy Efficiency – Using heat (Kelvin)?
A power plant taps steam superheated by geothermal energy to 505 K (the temperature of the hot reservoir) and uses the steam to do the work in turning the turbine of an electric generator. The steam is then converted back into water in a condenser at 323 K (the temperature of the cold reservoir), after […]
I’m looking for someone to invest into my ideal?
I’m looking for someone,who wants to invest into my power plant, from burning corn stalks. I have a plan wrote up on how to power a steam turbine generator. I have all the power sold to midwest energy cooperative for .05 cents per kilowatt.I want to produce 2000 kilowatt per hour, so that’s $100.00 hour, […]
Steam Engine to Power Home in Emergencies?
I have decided I want to get a steam engine, so I can power my home in the case of long term power outages. Before I get lectured about gasoline generators, solar panels and wind mills… I have considered those options, and I have decided a steam engine is the best long term option for […]

The matter contained in living organisms, also called _____, contains chemical energy. (1 point) biomass fossil fuels kinetic energy energy transformation 3. A _____ transforms kinetic energy into electrical energy. (1 point) generator turbine […]
Why do many assume the rate at coal fired generation is proportional to usage?
I have seen many responses that people hate the idea of using electricity wastefully because they want to cut down on the use of coal. With a coal fired generation plant, they have to burn at a high rate 24/7 to keep the superheated steam moving to the generator unit turbines, whether people are actually […]
Is solar heat to electricity totally non-air-polluting?
Once a solar to electric power system of oil in pipes gathering reflected suns heat in a suitably arid local and then using this heat to turn steam turbines to power generators or alternators and the system maintained can such a system be considered as totally non-air-polluting? dennis mac
When electricity is generated, where do the electrons come from?
I know that in a generator powered by a steam, water, or wind turbine or whatever turns a magnet which is surrounded by a very long wire. The magnet pushes or accelerates the electrons in the wire to produce an electric current. I know that if these electrons aren’t being continuously replenished, then the wire […]
Can you help me with my alternative energy science questions which has energy transformations and generators?
1. What form of energy is released from a bowling ball, a car, and a computer? 2. What energy transformation occurs when a solar calculator operates? 3. What energy transformation occurs when burning a campfire? 4. What energy transformation occurs when you rub your hands together? 5. Why does a student feel hot when they […]
How difficult is it to be accepted into Nuclear Propulsion Officer Candidate (NUPOC)?
I will be a rising senior in at the University of North Carolina at Charlotte. I am double majoring in Electrical Engineering and Physics. My GPA is currently a 3.051. I am working an internship at the Electric Power Research Institute in their Nuclear Steam Turbine Generator Sector. I am currently in the application process […]
Spills and Chills
Spills and Chills On the rare occasions that political rhetoric seems to understate a problem, it’s big. BP has a big problem in the Gulf of Mexico , which they are now properly laying out. Blaming the company for the spill is possibly a bit overdone since it was after all an accident. Read more […]
Generator Circuit Breaker?
When is it essential to put generator circuit breaker before the step up transformer? usually for which type of power stations (Steam or gas turbine)?
How can I get prices of electrical power generators ?
Steam and gas type for more than 100 MW out put.
How much mirror would I need to boil enough water to generate electricity?
I’m wondering what it would take to generate electricity with solar power but rather than use panels, I want to use mirrors to boil water and turn a turbine. Say I wanted to turn a typical car alternator/generator with steam. I set up mirrors that shoot light into a collector, boil the water, spin turbine, […]
