Wind turbines are cool. The might not be able to replace all the coal power plants in the world, but they’re a great example of how old concepts and new technology can be put together like peanut butter and jelly to become a delicious source of power.

They’re also a great example of the sort of positive environmentalism that sees efficiency and economic growth as two sides of the same coin. I would go so far as to say that most of the various groups opposing wind farms around the country are really lame.

But what if I wanted to join in on the blade-spinning fun, instead of just blathering on and on about it on the Internet? There’s a cool-looking rooftop vertical-axis wind turbine (VAWT) from a company called Mag-Wind that looked really promising when I first saw it late last year. It’s compact, doesn’t require a tall mast, and it’s designed specifically for roofs.

Unfortunately, it might not be on the up-and-up.

I’m a big fan of wind power. No, it’s not a magical solution to all energy problems. Wind turbines are a worthwhile component of a cleaner, more efficient energy grid.

As large-scale wind turbines become more popular, cost is going down and efficiency is going up. As far as I can tell, the main argument against the big windmills is that they despoil the landscape. It turns out they don’t really kill that many birds.

After seeing a few in action in Mackinaw, Michigan and on a trip to New York, I’m not sure what all the fuss is about. They’re actually pretty graceful – the new ones are so large that they don’t need to spin like a propeller to generate a lot of power.
