Yes, but from my limited knowledge on the subject, I am pretty sure it is mostly used near or on geysers (for obvious reasons) because it would take a lot of drilling to get to the really hot spots of the earth... But what if someone built a power plant running on volcano power think of some building just sitting atop a volcano harnessing its power...

I saw a video of someone with a simple water wheel and alternator to produce electricity to light their remote cabin. If someone is in a valley, any water flowing down hill could be a good resource.

I like this idea. We just need a big balloon...or how about a blimp. Attach some wind turbines to it somehow. Have a certain percentage of the power go to heating elements inside the blimp to keep the air inside hot enough to keep it afloat. Any energy beyond that would flow down wires to the ground (it would have to be tethered of course).

Now I just need a blimp. Anyone got a blimp they want to give away?

I have to admit, I did steal the idea from a show a while back that focused on "saving the planet". They actually built one. The either thing (even the turbine) was the balloon. So one balloon spun in the middle, and on each side was other balloons (I'm guessing tethering it and holding the generators.) It was COLOSSAL! I loved the idea though.

That's the problem with a lot of people when they think about "green" energy. People who want to make money off of it try to build HUGE things that'll power a small town. When in reality, if people mass-marketed things the everyday person would use (easily) to power their own home, they'd probably be much more successful.

Yeh I also have an interest but you'll just sign us all up for an early grave, heating up water will cool the world. not in the next 50 years but it would cool it down eventually.

I think permanent magnets to run generators is the way forward. Yes the magnetism reduces after about 200 yrs but by then we will have found a larger magnetic source to harvest. Imagine a hoover running on a permanent magnet motor. Hoover anywhere you want!!???

Drive non stop without putting fuel in your car.

Depending on power produced, maybe used to power jet engines to make space travel easy. No requirement for heavy fuel loads makes lighter rocket travelling faster to new parts of the solar system and beyond..... I really need to stop thinking up all these ideas without putting them into practice.

You heard it first here.

Don't DC motors (essentially generators) already have permanent magnets inside of them?

I think d13rce is talking about energy from magnets... like some kind of over-unity, perpetual motion device... doesn't work that way.

Yea, the over-unity stuff is bogus. There are videos all over youTube about it. I even saw one that was a pump that squirted what on a paddle wheel that turned a generator to power the pump. Yea, the demo looked like it worked, but it was inherently flawed.

There is also a guy that makes magnetic reactors and daisy chains them togther. The more he added, the more he thought he was producing energy, but for some reason he couldn't remove the battery he had powering the motor to drive the thing. I found it hilarious to watch because I think he really believed he discovered something new.

That brings up an off topic thing I love about youTube. People are always posting outlandish claims like the biggest, the only, or the best ever. They don't seem to realize they would have to be omnipresent to know that their claims are true.

These things are very interesting, although i have seen very little discussion about them, basically you can heat your water and house constantly for the equivalent electrical cost of running your refrigerator, combine that with a small turbine or some decent solar panels and you could feasibly live off grid permanently and be self-sufficient

I don't want to discourage anyone by saying something won't work so forgive me if I was a little too blunt with over-unity. I have always heard that the people saying something can't be done need to get out of the way of people doing it. I am just pretty certain with the over-unity stuff and don't want to see someone waste their time with it.

That being said, there are very good things magnets can be used for. They are used in motors, but there are other applications. Reducing friction comes to mind such at trains riding on them. I believe that the mono-rail at Disney does this, although I don't think they use permanent magnets.
