Is this any good?
What appears to be their main point - constructive interference between the turbines - is just flat-out wrong. A flock of geese flies in formation because there is less energy lost to drag (ie, the wind). A turbine is generating from the wind, so the concept is reversed: putting tubines in formation results in less energy being gained from the wind.
Other than that, it doesn't really say anything at all about the fundamental selling point of any wind turbine: cost per kW.
With shafting like that, the rotor dynamics of that thing could be a nightmare. I doubt this thing will ever get built.
