In effect, nature does this already. The sun heats up a patch of ocean, water evaporates and rises into the atmosphere. The vapour then condenses on airborne aerosols to form clouds which are then moved by winds and given the correct atmospheric conditions, rain falls. To produce significant amounts of water from a solar still would require either an ...

I think this is one of the "gaping holes" you are looking for: The amount of Total Dissolved Solids (TDS) in sea water is about 40,000ppm. Thus for every 1,000L of sea water distilled, you would have 40L of solids left behind after distillation. The amount of room left for water (i.e. the capacity of the 'hole') would thus decrease by 4% each time it was ...

A solar still CAN convert sea water to potable water. They are commonly included in lifeboat kits. Check the Watercone or this survival guide.

Here are a couple of papers published between 2011 and 2016: Ranjan, K. R., and S. C. Kaushik. 2013. ‘Energy, Exergy and Thermo-Economic Analysis of Solar Distillation Systems: A Review’. Renewable and Sustainable Energy Reviews 27 (November): 709–23. doi:10.1016/j.rser.2013.07.025. Velmurugan, V., and K. Srithar. 2011. ‘Performance Analysis of Solar Stills ...

What do we use water for in every-day life? And can we use untreated seawater instead? Because: untreated seawater is what the PO's is supposed to use instead of fresh water. :) Bathing. Maybe Either in the sea or in the bathtub. Yes, if you want to cool down and don't mind the salt. No, not if you want to get really clean. Or should we update our ...

I'm afraid the answer is no. Greenland alone has enough ice to raise sea-level by 7m. That is, 7m of water spread over the oceans which cover 71% of the Earth's surface. The flow of Alpine glaciers could be dammed, but this is not going to make a significant difference. Greenland is slowly melting now, and it is unclear whether this can be stopped. There is ...

It sounds like what you're talking about is geoengineering: the deliberate and large-scale intervention in the Earth's climate system. An interesting paper was published just last month that addresses this very question -- geoengineering strategies to limit sea level rise, specifically by reducing glacial flow: "Glacier geoengineering to address sea-...
