The world needs a new source of energy, an unspillable source.

Part 3 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 3 of 6. The total length of the combined presentation (all six parts) is 55 minutes.
