Wind-Harnessing Bike (US 6932368)

Finally, a mode of transportation for the avid bicyclist who is also a die-hard sailing fiend: This wind-harnessing bike relies on the massive sail attached to its back wheel to move forward instead of conventional peddling. According to the summary of this 2004 patent, "no one prior to applicant has succeeded to devising apparatus including a sail attachment connectable to a bicycle for harnessing wind to drive a bicycle forward in a controlled manner." Go figure.
