Whirling Twirling Propeller Trike

hankmt writes "A student at MIT has built a tricycle that applies force to a giant rear fan, instead of directly to the wheels. The effect...well, it's best to look for yourself, but it would be pretty useful on the post-apocalyptic roads of the Australian Outback. The blades of the trike even have built in LED lights which display colored patterns...and also warn pedestrians of their impending deaths."

It helps keep the pants leg from getting caught in the chain. Don't let that get in the way of your "gangsta" knowledge, however.
