If energy can only be transformed is it possible to change heat into electrcity?Also, how do solar panels work

Question

what are the principles of energy?
How do we control how we want it to transform? What steps do we need to follow? What do we need to know?
Can electromagnetic waves create propulsion? If so, how?
Can sound be used to push something forward? If so, how?

Answer 1

All common generating plants work by converting heat energy to electricity. The heat comes from a nuclear reaction or a fire that burns coal, oil, natural gas, peat moss, or anything that will burn.

For much more information, including pictures, diagrams, and animations, do an internet search on "power generating plant."

Hydroelectric dams harness the heat of the sun by using water that the sun previously evaporated and that later condensed into rain to fill the river that powers the turbines.

For much more information, including pictures, diagrams, and animations, do an internet search on "hydroelectric power."

Geothermal power plants harness volcanic (magmatic) heat in the form of steam from underground water.

For much more information, including pictures, diagrams, and animations, do an internet search on "geothermal power."

Solar panels use semiconductors that trap photons from the sun in electronic form and take the energy off in the form of electric current.

For much more information, including pictures, diagrams, and animations, do an internet search on "solar power."

The "principles of energy" make up the content of several college courses and many shelves of books. A vast subject that will not fit in this little box, no matter how fast I type. Start with a high school or college course in physical science. Also, go to the library and ask for help finding information on energy principles and systems.

The rest of your questions are in the same category. You need to study these things on the level they exist on.

Lab experiments can be performed with electromagnetic propulsion and with using sound to push small, light objects. These are not practical on an engineering scale.

Good luck, and have fun learning!

Answer 2

If you mean car roof the answer is no. It can't produce that much energy. At least not with the solar cells we have today. They do have experimental cars that have ran almost across Australia that relied on solar panels and an elect motor, but the panels were big and the car was small. It didn't produce much HP thou. If you ment a house roof solar panel, then the answer is yes. You could use the panels to charge batteries for the car. However, you could charge them with house currents just as well and probably cheaper considering the cost of installing solar panels and the risk of a hale storm destroying it.

Answer 4

Yes, heat is routinely changed into electricity.

As for the rest.......... You really, --really-- need to take a few Physics classes ☺

Answer 5

Are you asking somebody to do your homework for you? It sounds like you are.
