Stanford’s Yi Cui, assistant professor of materials science and engineering, has led the development of battery research resulting in a “silicon nanowire battery” that “produces 10 times the amount of electricity of existing lithium-ion, known as Li-ion, batteries. A laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers.”
This can’t be commercialized soon enough! Couple this kind of battery with this kind of processor technology (also claiming a 10x improvement) – and battery life should be a worry no more!
