Re: [Phys-L] Impossible vehicles revisited



Veritasium was called by a UCLA physics professor on his video claim concerning going directly downwind or upwind at faster than windspeed,including the amusing demonstration of a model land-yacht on a treadmill in a still air environment proceeding up wind so to speak, actually up tread mill track.Mark Drella (Aero Prof at MIT), the science guy and more were involved!
