I forget the details but vertical axis wind turbines are always less efficient than horizontal axis turbines. Off the top of my head I can't recall if the reason is that vertical axis turbines always have half of the rotor turning against the wind, but there is a basic reason I believe can be found on wikipedia.
- willvarfar 7y agohttps://en.wikipedia.org/wiki/Vertical_axis_wind_turbine https://en.wikipedia.org/wiki/Vertical_axis_wind_turbine says > research at Caltech has also shown that a carefully designed wind farm using VAWTs can have an output power ten times that of a HAWT wind farm of the same size etc The cups on the normal wind speed sensor have less drag into the wind. It would be easy to imagine a VAWT where a computer knew the wind direction and feathered the blades on the back sweep etc?
- TaylorAlexander 7y agoInteresting. I think I was wrong that the disadvantages I had seen before were easily found on Wikipedia. But I do see this quora post with bad things to say about VAWTs: https://www.quora.com/What-are-the-pros-and-cons-of-vertical-axis-wind-turbines https://www.quora.com/What-are-the-pros-and-cons-of-vertical...
