Nice paper, how did you find it? Assume you posted in response to the recent YouTube video.
The paper shows the math for land and water versions. Says a vehicle was tested in Feb. 1969, got an estimated 15 MPH out of 10 MPH breeze, but they kept having trouble with the chain jumping the sprockets (just like the YouTube video).
One interesting point is that the propeller runs in "windmill" mode up to a certain point, with the prop driving the wheels. Then the blade pitch is adjusted, and the wheels start driving the prop.
