The MCS approved list of small wind turbines includes 31 models, but none of them are vertical axis any more.
Quiet Revolution QR5, the darling of the architects, is no longer listed there. Instead the company have quietly shifted to marketing a chinese machine, the Hy5
A news story about the quiet revolution turbine “£48k wind turbine creates £5 of power a month”. Bad siting of poorly chosen technology has proved another huge embarrassment for the wind industry once again. Mick Sagrillo’s comment: “So, what’s your problem? It’s a VAWT. They don’t need tall towers or exposed sites, remember?”
But there is still a lot of vertical axis hype around on the web, and people still seem to love it.
