If you thought propellers were just for old planes and geeky hats, then you might want to think again. Take one MIT student, Damon Vander Lind, one three-wheeler made from chromemoly tubing and one bloody large propeller and strap them all together to make an eco-friendly fan-propelled and pedal-powered trike.
Make sure to check out the video after the cut!
Part of the DIY Rally 2007, the Propeller Trike uses a 7ft prop and salvaged bike parts. The propeller blades actually light up at night, thanks to embedded LEDs. I guess that’s one way to stop small children from trying to walk into them!
