The device pictured below, when placed on flat ground in a medium breeze, will spin to face the wind, right itself, and roll at 90 degrees to wind direction. Next task is to prototype two more complex designs to go directly into the wind.

This project was one of several designed to demonstrate far fetched concepts. Others were boats that sail directly into the wind, a rain powered vehicle, flying spheres, the ProtoAndroid, and a flapping wing flying machine that runs on legs to take off.
This work was done in Austin, Texas by David Santos. First sailed on 12-14-95.
