I had an idea, my parents complain about the high energy usage if my computer, could it be powered by solar? Also, what do you think of my idea for a heat engine(makes electricity out of heat)?

_________ l -------- l Turbine Turbine l l l l l l-------l l ----------- Hot plate

As the water is heated, it will rise, powering the turbine, when it cools off, is sinks and powers the other one. In order to keep the flow of water moving in one direction, the hot plate could be slightly off center. I was thinking that if you used a black surface instead of the hot plate, the you could have it heated by the sun, and be able to make a small scale solar generator, perfect to power at the very least a light bulb, hopefully a computer.

That's one helluva gap. Can you be more specific?

you need a lot! of power to run one, plus you can't power a computer directly, you need a battery pool of some sort.

Think of it this way, if it was that easy, don't you think we would all be doing it?

I thought of something like that awhile ago, except it'd need initial power to the comp. After it gets started, you'd heat the water using the CPU and it'd basically be the same from there. It wouldn't be enough though, but it's a good plan (in my mind).

Well there are a few concerns that I have, such as voltage and efficiency

Well I dont tthink you could get enough heat to evaporate enough water fast enough. Also you would have to supply water to the unit in the right doses raising your water bill, unless you have a well, but if you do have a well you still are using power to pump the water to your setup.

That's called perpetual motion. Unfortunately, it defies the laws of physics. ;)

For what you want, you'd need an array of professional solar panels (think $1k+), and even then you'd only be able to power a SFF machine at best. (Perhaps an ITX rig.) Plus, it would only work during the day, unless you have an array of aux batteries. :p

mm sorry the but no. the Heat used in a hot plate will take longer IE more energy to heat up the water in the reservoir and then in to steam by that time the air around the reservoir would be cooling down the steam back in to a liquid state from a gas and the energy in would = a very low fraction of the energy put in would come out.

I think you guys are confused, I don't plan to turn the water into steam, but hot water rises, that is my idea.

but surely not with enough force to turn a turbineat such a rate which would generate enough electricity to power a comp (unlike superheated steam which theorectically could). Not true Rookie_42 i once made a perpetual mption machine once. Simply take a cat (which lands on its feet) and strap a piece of toast to it and butter the side facing up...then drop the cat and the two opposing forces will cause it to spin in the air :D :P
