This seems odd to me - Venus has high wind speeds in the upper atmosphere, but on the surface the winds are only one or two m/s. Is that enough to wind a spring?
- philipkglass 9y agoYes, because atmospheric density at the surface of Venus is 67 kg/m^3m, about 55 times as dense as sea level atmosphere on Earth: https://en.wikipedia.org/wiki/Atmosphere_of_Venus#Troposphere https://en.wikipedia.org/wiki/Atmosphere_of_Venus#Tropospher...
- milesokeefe 9y agoWith sufficient gear reduction any wind at all is enough to wind a spring, albeit slowly.
- bad_alloc 9y agoWikipedia says: > Savonius turbines are used whenever cost or reliability is much more important than efficiency. The German article is a bit more detailed and claims that Savonius tubines are effective at speeds as low as 2m/s and produce high torque even then. Maybe the high pressure on Venus increases this effect?
