Powerpaste, a hydrogen technology for small vehicles
In '99, while working at a solar hydrogen startup as a recent grad, I was exposed to a fellow who proposed to transport H in the form of H2O, and his solution for cracking it was to make purple ping pong balls filled w/ Na. He'd deliver a hopper of Na ping pong balls, and a machine filled with water. Feed balls into the machine, which would then use a ram to split the balls underwater, and siphon off the resulting H2 gas to feed to your fuel cell.The racket it made, with a loud kerchunk splitting the balls, and the hissing immediately following, was just slightly terrifying.This paste seems a good deal saner in comparison.
