We use vacuum desalination. We use a small solar powered vacuum pump toi apply just 1m of vacuum to sea water. The water boils – losing all salts.
The town of village them uses a string of solar pumps to carry the water vapour to a holding tank or reservoir.
As the water vents, it condenses as pure water. Absolutely tastless – but safe to drink.
For for the price of the vacuum pumps, ot a wind turbnie, we have endless fresh water. We can use this idea all ove rthe world, to purify sea or river water.
