The S1500 floating turbine’s operating altitude is 4,921 feet above ground level, where wind speed moves about three times faster than at the surface. The advantage of this altitude (also referred to as vertical slice) can result in a power output up to 27 times higher than a conventional ground-based wind turbine of similar capacity.
The capacity to generate one megawatt of electrical power (MW) with the S1500 system is comparable in size to what small wind power turbines normally generate (a conventional 328-foot-tall wind turbine), while the footprint of the S1500 system is significantly smaller. This amazing power density shows the efficiency benefits of being able to access high altitude wind power resources by new and innovative airborne platforms.
That’d be my guess as well. How big just that winch be to wind in 4000 feet, though?
Playing with https://telecom.samm.com/cable-reel-calculator, it seems like you could probably fit a reel or two on a trailer?
I seem to remember the current wind turbines need some specialized trucks for maintenance too, this doesn’t seem like it’s need much more - but I’m not an engineer!
