The inhabitants of these islands rely
on the water they get from their food – primarily coconuts. But
they have loads of sun shine.
We use this to drive solar pumps. So
during the day, they pump sea water up conical structures – as when
sea water is under a meter high, the water boils.
Losing all contaminants and salts. We
then have a chain of vacuum pumps, to transport the water into the
interior – where we erect water reservoirs.
When we vent the water vapour, we get
cold water. That will fill the tank. We then have pipe lines,
distributing the water to the villages. So for the cost of the
vacuum pumps and pipes lines, we get fresh water.
Charities like Water Aid should build
the infrastructure. This works all around the world – covering sea
or river water into fresh, drinkable water.
