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 5 of 6. The total length of the combined presentation (all six parts) is 55 minutes.
excellent demonstration! Thank you for taking the time to show and explain this phenom. Not new science, been proved in the past but now we see it with a little bit of work. It would have been nice to see display.
