> I imagine a single "blade" would be moved less by the same amount of wind, but there are probably plenty of factors I'm not considering. Modern wind turbines have a cut in wind speed of maybe 3.5m/s and my guess is that these wind masts don't have a cut-in speed. So in low wind resource regions they may be effective at capturing market share because they can produce electricity with only a slight breeze. > I imagine scaling these up you have some pretty crazy engineering problems to overcome, like how to deal with the repeated strain at the base. Modern turbines have plenty of vibrations that the tower and foundation have to deal with. I was in the nacelle of a wind turbine when a surprise small tornado came to town, we were full on rodeo mode with the tower swaying back and forth. That being said on a day to day basis most of the forces are countered with the rotating mass (someone else can explain this better than I) so the turbine doesn't transfer much horizontal load to the foundation. With the wind mast there would be most horizontal load on the foundation as there is not another blade or two to counteract the motion and thus it would require a larger foundation. If you want to buy a 4kw turbine you can find one used for under $7k which is much less than this new technology. As better 3 bladed tech comes online there will be a larger second market for used turbines and thus might be a better economic option then buying unproven new wind mast technology. Pairing used or new wind tech to batteries can really benefit the offtaker depending on the marketplace.
