Water isn't really the fuel.
Another "water-powered" device has hit the market. The latest version from an outfit called Bedol What's Next is attractive and maybe worth the $16 as a conversation piece.
But like other clocks and calculators that came before, it's hardly a breakthrough in new "green" power. As is explained on a site where physicists gather, the power comes from slowly dissolving metal that's immersed in the water—not from the water itself. Not much different from the potato batteries that kids play with.
