First of all, I didnt say it was cheating. Obviously, because the rules permit CO2 systems, its legal. I said that I think they are a bit of a cheat, and I think Ive sufficiently conveyed what I wanted to (CO2 systems enter the arena with immediately usable energy that needs no chemical conversion, and ICE and electric motors dont have that luxury). Its inconsistent. And nowhere did I say that non-CO2 bots *couldnt* create usable energy. Obviously, there are plenty of excellent non-CO2 bots.

I dont know where you were going with the 15 kg linkage stuff. I was just demonstrating that you dont need 100000rpm to have a useful flywheel.

As for the energy storage in a gas system, Id have to look into my thermodynamics texts and refresh my memory a bit...or alot.
