Fuel cells that react liquid sodium metal with air could be the power source required to give electric airplanes much longer ranges, a new paper has proposed. The idea has yet to leave the laboratory ...

Fuel cells powered with the metal could provide a new source of electric power that's far more energy-dense than lithium-ion batteries. A new type of fuel cell that runs on sodium metal could one day ...

In lieu of high-explosives, an exploding wire circuit can make for an interesting substitute. As [Hyperspace Pirate] demonstrates in a recent video, the act of pumping a lot of current very fast ...
