mattnyc99 writes "There was plenty of chatter last week about an MIT announcement that researcher Angela Belcher had developed a way to create virus-based nanoscale batteries to power mini gadgets of the future. In a fascinating followup at Popular Mechanics, Belcher now says that her unpublished work includes full-scale models of the batteries themselves, and that they could power everything from cars and laptops to medical devices and wearable armor. Quoting: 'We haven't ruled out cars. That's a lot of amplification. But right now the thing is trying to make the best material possible, and if we get a really great material, then we have to think about how do you scale it.'"
