Chemist Don Gervasio and colleague Sonja Tasic, both at Arizona State University in the US, set out to develop a fuel cell that would generate more electricity for its weight than the best batteries, and would also work at room temperature.

Gervasio's solution was to use the alkaline compound borohydride. A 30% solution of borohydride in water actually contains one-third more hydrogen than the same volume of liquid hydrogen. "The difference is that the borohydride is at room temperature, and it's stable, non-toxic and cost-effective," Gervasio says. The borohydride solution releases its hydrogen as it flows over a catalyst made of ruthenium. The hydrogen passes through a membrane and combines with oxygen in the fuel cell, generating electricity and waste water.

Theoretically, this could achieve an energy density up to about 2200 watt-hours per litre Gervasio says, compared to 200 watt-hours per litre for a lithium polymer battery.


2000 Wh/kg! Now that's some serious improvement in energy density. The catalyst packs are going to be expensive as hell, but aside from that this sounds amazing.

While definitely not dinner companions after hours, the two respect each other on the job. "I wouldn't spend five minutes with Adam outside work if I didn't have to," says Jamie Hyneman. "But yet I feel somewhat displaced without him in the workplace ... destroying my tools and leaving messes everywhere he goes."

Hail Eris! - The planet(?) formely known as Xena will now be officially renamed "Eris" - Greek goddess of chaos. Fitting, given how much infighting it has sown in the astronomical community. ;]

Bionic arms on the march - I have noted before that I, for one, welcome our new bio-Strogg humanity liquidators.

The Nintendo Revolution will be region-free! - Alright! Nintendo GETS it! Region coding = locking out potential customers. And yes, Nintendo's newest console will always be the "Revolution" to me, not that skin-crawlingly pink girly name they've given it. (Not that there's anything WRONG with that...)

Diebold voting machine utterly pwNzd - Oh sure, like nobody saw THAT one coming. Bruce Schneier said it best: electronic voting machines need to have paper trails verifiable by the individual voter, or they're untrustable crap.
