Okay so I had this thought. The winds that travel in between skyscrapers in big cities much reach colossal speeds, these winds could be used to generate energy. So why not install wind turbines in big cities? Here's a small render I made:
Simple enough? Well here are some problems:
; from what I've heard wind turbines can be quite noisy, something that big cities usually have enough of.Accidents
; Wind turbines a prone to break when the winds get to high. Turbines can break and scatter parts. This would of course be extremely dangerous in big cities if people live or travel near them.
But if they were installed in places where people don't travel, like in secluded alleys, with some kind of protection around them, it might be safe.
Random afterthought: 3 dimensional wind turbines? Hang them on an axis and the could turn with the wind, like a flag hanging on a flagpole. => More efficient turbines?
