Stansbury's idea is to convert the large Blazer into an electric vehicle and then outfit the beast with a few different technologies that will all "absorb the energy around us, namely the sun" and power the batteries. These technologies include small turbines in the front, photovoltaic panels on the sides and solar thermal collectors on the roof. What do the collectors do? They heat water to power a stirling engine that generates electricity. All this "free" energy will power electric motors in the front and the back of the Blazer. Oh, and one more thing: the Havasu team wants to place wings below the batteries and on the roof to exploit ground effect and provide lift.
All in all, this is a very interesting project. I'll update this post with some more info once I get to a scanner (UPDATE: you can read what the Lab thinks the technology will cost by reading this letter). For now, enjoy the interview with Stansbury and contemplate just what it would mean if a freakin' Chevy Blazer won the Auto X Prize.
