Jay Rogers' Local Motors has produced 60 off-road rally cars. The really interesting part is how they were built--with a crowdsourced design and many suggestions from the Internet, which changed everything from the engine (goodbye BMW, hello Corvette) to the door fit.

The Danforth Plant Science Center in Missouri is a cutting-edge lab for developing tomorrow's biofuels.
