This is an aerodynamic oddity so I'll drop it here.

I've mentioned a few time that R. B. Fuller advocated for indoor windmills. I've always liked the idea. Here's someone who gets it.

It's not clear about their hubless rotor design but the converging duct is the key. This needs to be embedded at the zenith of a sizable hemisphere. Then the guide vanes can be extended to increase that 40% factor. Putting it on top of the hemisphere increases the nominal wind speed even more.

It appears to be a 1kW device. There is a Kickstarter page, but it doesn't like Raspian's system clock.
