From Walter Jon Williams' Blog:
The Bloom Box is an in-house power generator. If I read the article right, it uses fuel and oxygen to cerate emission-less power. I've been waiting for something like this since my father (who worked at a power utility) told me what a fuel cell was, some thirty years ago.
He also said (my father is very smart) was that "utilities are interested in more than just electrical power." And from watching PG&E's antics for close to a decade, he wasn't wrong. So keep an eye on the Bloom Box. This will be a massive decentralizing influence if it works half as well as advertised.
Although it's touted as an emission-less energy source, it's not a fuel-less energy source. We won't be able to replace the amount of petrolium fuel America consumes with biofuel. There simply isn't enough arible land. But I would like to see the efficiency numbers; how many coal-burning power plants will we be able to take off-line if these suckers work?
And how soon before they're small enough to stick in a car?
