Doesn't change a thing on how stresses damage the turbine. Vertical still only makes sense in limited space.

- Clewza313 5y agoInterestingly, vertical designs have been proposed for Mars, because space for shipping them is at a serious premium, and the much lower atmospheric density reduces the stress considerably. (Hollywood depictions of destructive Martian sandstorms are quite exaggerated for effect.)
- p_l 5y agoMars is a good example of differing constraints leading to choice of different technologies, indeed.
- juststeve 5y agowhat are the stressors? mechanical failure, too much kinetic energy in the waves?
- opwieurposiu 5y agoThe pole in the center of the VAT generates a turbulent wake that the blades pass through once every rotation. This wake shakes the blade and causes extra stress. The blades themselves make a wake also, though not as much as the pole. The horizontal turbines put the pole behind the blades. The pole does make a bow wave, but it is not as bad as the VAT wake. The pole/blade interaction is not as severe.
