145GW of power needed to raise water up 640m. Desalination not included, may be necessary. Would require 12k high-end wind turbines given local wind conditions. This is around 25% of current global wind capacity.

- learnfromstory 7y agoDoes 12000 windmills sound like a lot? Consider that we have 1.7 million oil wells in the USA alone.
- NeedMoreTea 7y agoWhen you consider that's 12,000 for the least energy intensive part, just pumping the water, yes. A hell of a lot. How many extra windmills for desalination and freezing to produce snow? How many acres or square miles of desalination plant? How to dispose of the few(!) tonnes of salt? How much of the world's shipping, construction and engineering requires commandeering, WW2 style to ensure it's a ten year not fifty year project?
