I will use a GE-222 wing profile. The good thing with XPS foam is that itis easilly shaped with a saw and sandpaper. When the wing is done it will
have a number of layers off fiberglass on it to make it ridgid.
A blog about my vertial axis wind turbine. I am designing and building a vetical axis wind turbine that I will connect to a grid tie inverter. I will try to reduce my carbon emission footprint, and perhaps save some money.
