They are cost effective because they are two small.
Sigh..People have tried to make these work. It always fails for the same reasons. To get good capacity factors you need height and good swept area – and you can get better height and swept area with the ‘conventional’ design.
Plus: The axis of rotation is always under sideways load which leads to high maintenance cost (whereas the ‘conventional’ design only has axial load)
So yes: VAWT do work, but they aren’t the best in terms of $/kWh produced (and that’s what counts)
That 6kW unit looks way bigger, uglier and more expensive than my 6kW rooftop solar install. No thanks.
Lmao what year is this? People kept saying these were the up and coming think when I was finishing my degree…
I graduated in ‘08…
who makes these vawt?
I used to build those in the City Skylines (first edition). Release date was 2015.
Sigh. This conversation again? VAWT are not revolutionizing renewable energy. For the reasons others have articulated below (swept area, torque), VAWT is a bad design.
Counterpoint: No, they’re not.
6KW seems pointless, when you could have one normal wind turbine in less space than those, delivering up to 4MW, which would be roughly 667 times better.
Or you know, like many countries, caring about green energy, place them offshore, then one wind turbine can do up to 15MW, which would be 2500 better than one of those 6KW vertical ones, and out of sight for most people.
(Vestas 15MW offshore, Siemens Gamesa even has 7MW onshore options).

What if we tried a 45° angle of rotation turbine?
