Gravity and thermodynamics-driven generator idea

[aleks]

By the way, I will be more than happy to hear any ideas AGAINST this system. I do not mean just Carnot's efficiency speculations - it's an obvious limitation. Let's assume we have a 100% COP thermoelectric generator which can collect all energy we have put to heat the gas. Can this condition prove free energy taken from gravity pull exists? In any case I see this idea as a good mind-bender to check one's physics knowledge.

The main concept that supports this idea is that gas (when heated) DOES NOT spend energy to push the heavy piston up. The heated gas is used as a temporary reservoir for energy, and the energy is used to change the state of the gas so that its pressure is increased. What is interesting is that the change of state of matter (gas) performs work without actually using any energy (the heat energy transferred to gas is contained within this gas and is not lost when the gas expands).

Also note that heating of gas (using electricity) should be assumed to be 100% COP process (electricity can't be "lost" when heating - any theoretical losses are converted into heat after all).
