As a follow-up to our post yesterday about the guy who set a new human powered boating world record of 107 miles by pedalling straight for 24 hours, I decided to show you this invention, the Hobie Mirage Adventure Island, a 16' Trimaran "Sail/yak". What in the world is a "sail/yak? Good question. If you can't tell by the big picture above, what you are looking at is a kayak with two outboard floats (making the vessel a trimaran) which has pedals and a sail. Therefore, you could pedal, row or sail using the wind. A tribrid, and all options use no fossil fuels, obviously.
The inventiveness does not stop there, though. The pedal drive operates flippers, generating thrust in the same way that a dolphin swims. The machine is not cheap, though. If you've got a spare three grand or so and want to give it a try, let us know how it goes. The rest of us will just make do with our goggles and flippers. Sheesh.
