Wired has a nice article of the High Energy Laser Mobile Demonstrator (HEL MD) by Boeing being developed for the Army. The system will eventually run a 50-60kW energy weapon, rather than the 10kW here. And controlled with an XBox controller…soon your fat game kid might be able to join the military and shoot stuff from your basement.

Kaner Lab researcher Maher El-Kady painted sheets of graphene an atom thick on a plastic surface and bombarded it with controlled laser light (he used a DVD burner.) The result: a stunningly thin supercapacitor which could store up a large amount of electricity in minuscule time frames. A battery made of this material could charge your cell phone for a full day’s use in two seconds, and is much lighter than current metallic batteries.
