I wonder if they consulted structural engineers. Putting multiple 1000 lb loads on roofs that weren't designed for it doesn't seem like a good business plan.
I'm not go worried about the load bit Zhou about vibrations.
Wind turbines vibrate, especially of you install them on turbulent airflow such as just on top of a roof. I would be worried that it would cause some long term damage to the structure.
Everytime I look into the same thing, it's always that these dont have a great turndown to small single unit scale.
Where solar is quite modular, putting 1 or 2 of these turbines on a house, that are also not tall enough to get above all the wind blockers (other houses, trees), just won't make sense for a long time.
Looks like covering big box stores gets around several of those barriers, which is great.
Turns out I haven't looked in awhile, but they have personal wind turbines to power your phone. I think putting a bank on one side of some homes could be great. In Seattle, with all of the micro-climates, hills and wind tunnels, this surely is a thing.
