Also, the inventor of Harmony Turbines covers one of the big drawbacks of conventional turbines. Conventional ones use brakes in strong storms to slow down, which can and will overheat and cause them to burn up and even explode.

Harmony Turbines however aren't meant to completely stop at all, I think you misunderstood how the furling mechanism is arranged. It's meant to keep a regular consistent RPM.

If the winds are low, it opens all the way up. If the RPM starts to exceed a certain limit, it starts to furl in until it reaches a stable RPM again.

Assuming they're built structurally sound enough, Harmony Turbines could indeed keep functioning right through a category 5+ hurricane, assuming a tree doesn't get blown into it or whatever, but basically everything is prone to storm debris anyways.

Regardless, like I said, consider the strength in numbers vs the absurdity of building planes as big as a football field...
