Infinite energy!? That would be quite a feat
I had an idea that bridges far out of my knowledge. but I've considered what would happen if you brought mass into a heterogenous, lower energy vacum state, forced it to undergo complete matter annihilation, took the electromagnetic radiation that came out of the lower vacum state, make it into mass again, and recycle.
I would need someone with a PHD in theoretical physics to even analyze whether or not it would work (and if mass and energy change as they cross a heterogenous vacum state, it won't) but from the little things I've heard about vacum state (its not reliable info, simplification etc.) thats the best option for infinite energy.
put simply, change the value of "c" in E= m c^2
Schem, how is it exactly that heat can be transformed directly into electromagnetic radition
well heat releases infared light, which is electromagnetic. but the problem is thats a slow process, there probably is a way to do it quicker. but I can't think of one, yet.
