"There will be a whole forest of domestic turbines throughout the country - it will be so normal to have one on your home"
Donnachadh McCarthy
---------------------------------------
This Horizontal & Vertical axis wind turbine is the best solution using by wind Power.
Mechanical engineers can easily distinguish a great difference between Third Member Wind Turbine and Horizontal-axis wind turbine or Vertical axis wind turbine. Because Third Member Wind Turbine has combined the effectiveness of both Horizontal-axis wind turbine and Vertical axis wind turbine to create a high torque with high rotation speed to the generator (Third Member Wind Turbine's benefits can be easily tested with time and has a low cost). Thus it can operate a higher-capacity generator with simple structure and low cost (or it can operate even wind at low speed, for small Wind Turbine satisfied demand for every household)
Note:
Third Member includes all of Bevel-Gear style and Planetary Gear style
---------------------------------------
During periods of sustained high winds the system may produce more power than is consumed, a financial return can be realized by selling the excess power to the utility company and through net energy savings.

I meant darrieus not savonius sorry...
By kreuzundquer [Affiliate User] 1263374981Why combine a vawt with a hawt?
U use a simple differential gear to add both rotation movements, i think the windmill wich generates more force will slow down the rotation of the other, wich is fatal for the savonius roter cause he has low torque and generates low power at slow rotation speeds. U will have to make sure that both windmills have excactly the same torque, in every wind situation, wich i think is impossible.
Correct me if I'm wrong!
Keep it simple stupid.

By foxwood1944 [Affiliate User] 1259021590You are right in one sense; Good engineering uses the least number of moving parts possible for lower friction / increased efficiency.
However, to convert rotary motion at right angles, planetary gears such as these deliver vastly improved rigidity and load-bearing, with only minimal increase in friction. The benefits of double or even triple gearing in high torque applications far outweighs a slight reduction in efficiency.
