I have another question . . . How does it know which way the wind is coming from? It would need some kinda mechanism to adjust the machine for wind direction. That is even more power needed to operate the machine. W o o f -={(

The blades will be pushed from one side when they should be deployed, the other when they should be edge-on to the wind.  If their center of effort is a tad off axis that will provide all the power you need to flip them. [ Parent ]

i like the idea of a horizontally hinged vane(on the upwind side ) as long as the wind could push the vanes back at an angle it would allow  air to pass through,   increasing efficientcy. the problem would be on the downwind side as all the vanes clatter back to their energy gathering  position this is were modern materials might help.   [ Parent ]

You have to combine HAWT tail mechanism with this machine and you get a very simple - 5 parts - blade tilting solution (there is no need for additional motors or whatsoever). And again, if the tilting is happening while blades are  paralell with the wind direction it should be effortless to turn them. [ Parent ]
