Do you know there is another energy source called hydrovoltaics It generates electricity from simple water evaporation No fuel no sunlight no external power needed I built a device that uses this effect and what is surprising is it works not only at room temperature but even in extreme cold at minus twenty degrees Celsius This shows that even in snow electricity can still be generated This could provide energy in remote regions and may help support solutions to the global energy challenge
