Brazilian engineer, Ricardo Azevedo, has developed a hydrogen-powered engine that has an external car battery and runs on water.
Dubbed the “T Power H20,” it works by splitting H2O into hydrogen and oxygen and using the hydrogen as fuel; the resulting combustion moves the vehicle.
In the following video, the inventor shows how even polluted water can make the bike move. Azevedo explains, “the advantage of this motorcycle, which works with the hydrogen that comes from the water, is that the result that comes out of the exhaust is water vapor. This is different from gasoline, which [produces] carbon monoxide.”
