  1. Excellent, thank you. We can do so much with wind, I now realize. I always did being Dutch, but the picture is clearing up tremendously now. Wind looks really good for transportation actually.

Part 6 of 6. The aeromechanics of wind powered vehicles using rotors for energy conversion.


Theory and basic mechanisms that make wind turbine powered vehicles going directly upwind work are explained by Mac Gaunaa. Furthermore, it is shown that the same theory explain how and why DDFTTW (Directly downwind faster than the wind) work. This is part 6 of 6. The total length of the combined presentation (all six parts) is 55 minutes.
