MirageDrive ~ Pedal-Powering a Hobie Kayak!

Just got sent a cool link by MIT alumna Mimi Slaughter for the ingenious Hobie MirageDrive -- a pedal-powered paddle add-on for a kayak! Powerful stuff as you can see in the tug-of-war between the inventor pedaling and an Olympian paddling... While this particular mechanism was invented over a decade ago, the general field of pedal-powering things is still blossoming!
