Of course, but I also have to work within the laws of physics. Toyota will not get more than 500 W/m^2 even if they spend money for another fifty years. They will not get a practical car down to 400 pounds with a drag coefficient under 0.1 either. Sell me an efficient car, yes. Environmentally sound, good. Personally I'd love to commute to work using the energy that falls on me every day (very evident in the desert!) but I'm saying that the energy has to be collected by large areas.
