<div>The big problem is Lombok is stripping trees from other islands, they need so much energy.

Yes I see now, sea water is around 35 gram per litre and boiling water<br>
saturates at over 400 grams but I couldn't see where the extra salt<br>
was coming from so assumed they were evaporating from sea water rather<br>
than a more concentrated brine.<br>
<br>
So if they were starting with a concentration of 20% salt then they<br>
would only have to evaporate 320 litres of water instead of the 2000<br>
litres I first worked out ( I also misread a decimal point one place<br>
in the saturation point of brine).<br>
