interesting take on the hydrogen storage problem. and on goverment involvement w/ tech. the us doe has filed a patent (governmental divisions like doe *can* file patents? thats got some interesting implications...) on a novel way of storing hydrogen in doped glass spheres that would work w/ normal pumps and tanks for delivery. pretty cool - i'd be interested in what the productions costs of the inert materials used are though, and what to do w/ the leftovers it when it's used.
