I could see where a vertical axis “drum” wind turbine might serve as a fill in to a mature solar system. In times where it is overcast and bitter cold in our area is when we have some of the steadiest wind. I would hate to have to rely on one as a main source of power. It’s like the notion of farm hydro: the creek I would eye for that would tend to destroy paddles driving a generator during our spring floods, and would handily lock a pelton turbine with rocks and grit at that same time. There are so many sites in this part of the country that are ‘Suchandsuch Mill Road’ where the furious flooding we get every 5-10 years long since washed away every vestige of the antebellum mill that place name refers to.
