battery boost

it's about time.
a new battery is in engineering.

Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory.

you got my hopes up until i read this in the rebutal

I didn't do the sums for a 25 watt tritium-powered battery; someone on Slashdot did (hi, /,!) and came up with the figure that you'd need 800 grams of tritium for a 50 watt battery.
Doesn't sound much, but tritium is an isotope of hydrogen - the least dense gas in the universe.

Assuming that tritium has a density roughly equivalent to hydrogen - around 0.08 grams per litre - that means you'd need 100,000 litres of gas. Per battery.
