How about free perpetual energy?

Some thoughts about the subject.

My believe is that the Second law of thermodynamics is no more than a meme. However I never seen or heard of proof of a working machine that violates the Second law.
The Second law states that you never can put heat energy for 100% into a other form of energy, You will always have a increase of Entropy that means you never get the same temperature difference back where you started with. The implication of this that in the long run everything will have the same temperature,
Total Entropy wil than exist. But there is something untrue about this, I wil explain this to you.

Little Demon In reality on a very small scale, the molecules of a gas or a liquid wil never have the same energy, some wil go faster than others, why this is you can see here.
If you where able to sort them out, you end up with a temperature difference, then it would be possible to convert it into a other form of energy.
The nineteenth century scientist Maxwell imagined that a little demon could be able to do the trick.
Go to the Maxwell's demon page for more info.

Feynman ratchet On this very small scale there is the effect called Brownian motion, small particles moves randomly because they are hit by the molecules of the gas or liquid where they are suspended in.
It would be a violation of the Second law if the weren't moving at random, this is the subject of the Brownian motion page go there to learn more.

A other possibility is this, in a vacuum you have only exchange of heat by radiation, al objects send out en receive radiation, when al objects have the same temperature the send out the same amount as the receive, if you could chance this you might get temperature differences for free, check out the Heat radiation page over this.
