Aeromine Technologies just closed a $9 million funding round, and it's ready to scale up production of its bladeless rooftop wind turbines.

      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.

    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.

        Should be, but my comment is more along the lines of I doubt many buildings can take additional multiple 1000 lb loads.

      Walls are made to support loads and TFA does say they are mounted on the edge so roof loads will be minimal

      Not to be confused with edge lords

        Commercial building like this have curtain walls. Curtain walls don’t support loads, the columns are the ones taking the load.

      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.

      Horizontal turbines are better if you have space. Verticals are better if you don’t. Verticals are popular in the hobby space because they take up so little space and require less of an engineering degree to maintain (… generally). I can see why they would put verticals on their roof over horizontals if they want to extract wind in a low-profile low-maintenance kind of way.
