boxthrower has a valid point here. More efficient engines is a good thing, but calling electric cars, solar panels, and wind turbines "green" is a pretty big stretch. It's more reminiscent of offshoring where the nasty parts are out of sight, out of mind. If you really want green, let's get nuclear. There's a new kind of reactor that uses a solid heat sink instead of water, but obviously can't be implemented due to regs.
