Is this what petro dollar cabal don't want is to develop?
Peltier is a solid state electronic device when current is introduced one side gets hot and other cold.
We can reverse that and we can create current by exposing one side to warmer temp and other cold. Everything on earth has difference in temp. Ground and Air for example. By attaching peltier to the ground and other side to atmospher current (electricity) is produced. Free Energy with tech already in mass production. However it is not cost effective today. Efficiency must improve. It's around 1W per sq inch at delta T of 500F. No where near plausible replacement of traditional energy production.
