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.
Have horizontal ones not been more efficient?
(ringblade and wind my roof for example)
