Low-power tablet computers could run on ambient solar energy

We need tablets and phones that consume so little power that they can run on ambient solar energy. That's something I didn't think of when I was talking about orders of magnitude gains in power generation and consumption. If our devices are efficient enough and our ability to generate power grows far enough, then we won't need central power stations at all. Your whole house can run on a couple of solar panels on the roof, and your portable devices can run on ambient solar energy.
