Graphene Battery Turns Ambient Heat Into Electric Current
- kolinko 15y agoThis sounds like a practical perpetuum mobile - right? I wonder whether their results will hold up.
- ajuc 15y agoExactly. If I understand correctly, this battery is supposed to decrease temperature of the solution AND produce energy in the process, without increasing temperature anywhere else? If so - this works in isolated system, and decreases entropy over time.. There goes 2nd law of thermodynamics. Am I missing something?
- biofox 15y agoI don't think any laws are being broken here. Energy will be lost in the transmission.
