> And on the surface, there's almost no sunlight and the windspeed is very low[...] Ignoring other issues with Venus (heat, pressure, acid...) "wind" turbines on the surface seem completely viable. The wind speed is low (reaching ~2.8 m/s on the surface) but the pressure is 90 atmospheres[1], or 67 kg/m^3, compared to ~1.225 kg/m^3 on Earth. If you plug that into a wind power calculator[2] you can see that with a conservative 1.4 m/s surface wind you need a 1 meter radius fan blade to get the same power as a 7-8 meter radius blade on Earth. So wind power on the surface seems completely viable, aside from the small engineering issue that your turbine would melt into a pool of metal in seconds with current technology. 1. https://en.wikipedia.org/wiki/Atmosphere_of_Venus https://en.wikipedia.org/wiki/Atmosphere_of_Venus 2. https://rechneronline.de/wind-power/ https://rechneronline.de/wind-power/
