You’ve heard of steam power—now, there’s evaporation power.
A team of scientists at Columbia University have figured out a way to generate electricity from harnessing the forces generated by water evaporation, not heated water, but water at room temperature.
In a steam engine, the mechanical energy from the rise of the heated water is transformed into electricity by a electromagnetic generator. An evaporation engine also harnesses electricity from mechanical energy, but it’s not from the upward pressure of the vapors, but the contractions of bacteria.
