Essentially a giant propeller you strap to your back when you ride, the Thrustpac can get you moving at 25 to 35 MPH. It runs on regular gas, and gets a very efficient 150 miles per gallon. In theory you don't need to be on a bike for this to work. A skateboard, roller skates, or anything with wheels should work just fine. There's no pricing available at the moment, but on the half-completed Pacific Wind website there's contact info, so feel free to get in touch and find out how much it'll cost to have a hilarious propeller-related death.
