The hydrogen-powered generator that was almost a home-shopping hit

Nice product. I'm curious to know how the cost of their catalyst compares with other major energy sources in price /joules. The website crucially excludes how long the fuel pucks last at peak power output. They may not have worked that out yet; they do say (in the pdf) they are planing on shipping packs of different energy densities.

Products like this are what fascinates me about innovation and entrepreneurship. If the economics of the product are right, or could improve through iteration - this could be more disruptive than the automobile. Cool beans.
