Ultra-Dense Deuterium - Fusion Fuel Found?

Omomyid (415252) writes "Scientists at the University of Gothenberg have successfully produced very small amounts of Ultra-dense Deuterium. It's so dense that a 10 cm3 cube would weigh 130 tons. UDD is 1 million times more dense than deuterium ice, a common fuel in laser-ignited fusion projects and would vastly improve the chances of starting a fusion reaction as the atoms are much closer together."

"Hydrogen... Fuel... Fusion... Sustainable... Non-Hazardous..." "BINGO!" Never mind the near-complete absence of content; this will run everywhere.

Here's a link to one of the papers (may require subscription outside a research institution; I can't check from here): http://dx.doi.org/10.1016/j.ijms.2009.02.014 [doi.org]

It looks like this phase exists in a few atoms for a few femtoseconds. They're saying it's a sort of "inverted metal", with deuterons moving in the electric field of the electrons. (In normal metals, the conduction electrons move around in the field of the more-or-less static atoms.) Interesting if true, but very, very fleeting.
