New Device Harvests Energy in Darkness

Just like change of voltage is what matters, change of energy is what matters. I find it fascinating that all of energy politiking rests on fundamentals of funding these huge differences between potential energy wells so you can add something vampiric and capture the difference as electricity or some other type of kinetic energy that we like...

The million dollar question is whether the vacuum has some potential difference that can be exploited for energy generation..
