I believe this wooden windmill is very innovative and challenging in its principles. I might try it some day, but I think there might be far easier ways to make electricity, especially in our new century! Good job, though! We'll see who can challenge the Bloom Energy method?!

Wood is certainly adequate for moderate size blades. It is still used for aircraft propellers, laminated as unidirectional plywood to avoid warps. Carving a first-class shape is not really hard. You can print out the station templates with an angle of attack line, and just set them up on your workbench with the blade on a hub to swing in for checks.

Having carved perhaps a thousand windmill blades in the 1980's I wonder why more people do not just go to a two bladed prop. My blades really flew, in about 10kts of wind, they filled the circle, ie in theory every molecule of air got to impart it's energy to the blade. fewer blades = less drag, although multi blades may produce more power in light winds.
But most people do not live in places windy enough to pay for a windmill. |
