Downwind faster than the wind - Part 4


The discussion about whether or not an unpowered vehicle can be made to go directly downwind faster than the wind (DWFTTW) is ongoing. I was reading the comments this morning, and came across a link to this intriguing video, titled "Under the ruler faster than the ruler." It's starting to make me think that a DWFTTW cart is feasible.

In the video, I was surprised to see which direction the big wheel turned when the ruler was run across the top. I'm also quite impressed that this fellow and others are making models to conduct experiment, instead of simply speculating. Hooray for amateur science!

As I've requested in previous posts on this subject, if you have something to contribute to the discussion boards, please refrain from insults and name-calling.
