Urban wind turbine wins UK James Dyson award

No mention of expected power production, no demonstration of this turbine actually generating electricity, and it’s extremely small (”The O-Wind turbine is a 25cm spherical device”)

That makes me skeptical, having read https://www.solacity.com/small-wind-turbine-truth/ (and a few of the links to actual tests)

If this solves the “doesn’t work well in turbulent winds” part, that may change, but if fear that, if it does, that is at the price of efficiency.
