Great tech, great product and I'm glad this tech is becoming a reality.

But (and it's a big BUT)...you have to be careful where, and how this tech is used. If my understanding is correct, the melting of the polar ice-caps is having a desalinating effect on the oceans already - and one which could have major impacts on our planet.

It was a while ago, but I read research where they were projecting that the desalination of the ocean could halt, or disrupt the Gulf Stream - which is like a conveyor belt, bringing warm warters from South America up to Western Europe. If this were to happen, much of Northern Europe could be thrown into freezing temperatures, and there'd be wider effects for the rest of the planet too.

So, yes this is good tech, but maybe it should be used very caredully and only if we're 100% sure it won't have a negative impact in one region, whilst massively helping another. I'm all for helping people get much needed clean water in the Middle East, or Australia, but not if it plunges much of Europe into a mini-Ice-Age!
