There are a couple of (small, obviously academic/experimental) vertical axis wind turbines near me which both have helical blades. I wonder what the tradeoffs for that design are?
Here's a picture (not mine) one of them: https://www.flickr.com/photos/nicephotog/25044930672/ https://www.flickr.com/photos/nicephotog/25044930672/

- hasmanean 6y agoFor very tall VAWTs in a grid, could you dampen the resonances by tying the tops of the masts together with guy wires?
- jacquesm 6y agoThat will make it worse, not better. You want to decouple as much as you can so you don't end up creating a giant resonant structure.
