A clever new method has been shown for cheaper desalination of water. It basically uses solar heating to convert seawater into concentrated brine, and then uses the ionic gradient between the concentrated brine and two seawater streams to pull salt ions from from a 3rd seawater stream, thereby desalinating it.
Given that the spineless Kaangress govt will see Indian rivers dry up after China dams them from their side, we'd better invest more effort into desalination technologies to mitigate the looming water crisis.

outstanding! this is the kind of radical stuff that needs to be done to make a serious difference. i hope this becomes truly commercially viable. instantly a city like chennai will become far more viable. in fact most of coastal tamil nadu, now parched, will become far more productive. and so will coastal gujarat.
