Well, this guy seems to know what he's talking about. I recall however, that energy savings in cars have been spent mostly on increased power and increased size, and only marginally on increased MPG. I wonder if a world using his stuff would use less energy, or just do more. Not sure, but that's the kind of problem that I'm sure we'd all love to have.
Until next time, remember that the all-time score remains Technology: eleventy billion, Malthusians: 0 (i.e., "we're not dead yet.").
