Against the wind
Against the wind
Jack Goodman from Florida seems to finally have found the proof for a controversial theses:
He built this cart to end an long argument on the Amateur Yacht Research Society website (ayrs.org) about whether DWFTTW (Down Wind Faster Than the Wind) is possible. In the end it led to more discussions, with some believing the video is a hoax. However, for me it looks reasonable. Check also Jack's writeup (PDF).

Thinking it through and having read Jack's writeup, I actually don't think anymore it's possible. I think rather that the propeller makes the wind indicator change. I wonder what would happen, if the indicator is positioned one meter higher...
