Here, sane proportions, size, strength, and costs of it all will be discussed. How much torque do we have to handle? How do we secure the device to the ground? Out of which materials can we choose, what properties and costs do they have?
Keywords: strong, safe, inexpensive, less friction, long lifespan. This is the art of taking a high speed, high torque ax, rotating the rotor close to the stator, and balancing cost with strength and durability. Build things out of steel, or foam?
We are still searching for a good free stress simulator, that will predict fatigue and breaking points in structures when forces are applied to them in windy conditions.
Also, try to find a way to divert lightning, or to minimize damage when a bolt strikes, at least. Make as less translations of power as possible. But if the generate power guys demand more rpm, and are willing to compromise torque for it, and lose some energy in translating, take a deep sigh, and do it. But complain about every time you have to translate energy. Best, only translate once: from blades to ax.
