i read an article not too long ago about a new graphene based battery (think chicken wire, but made up of carbon atoms) that could power an LED for 5 minutes and took 5 seconds to charge. this from a graphene sheet just a few atoms thick. the technology is still embryonic, but that's the future of portable power right there.
