I remember seeing that the Gates foundation had come to the conclusion that the greatest good that could be done for the greatest number, was to find ways to provide plentiful and cheap fresh water and energy.
Pretty much the rest could work itself out, but these were the long poles in the tent of improving the human condition.
I guess that such filters could have a big role in waste water treatment as well.
well yes.
Its a pretty sound theory. The way you grow a food chain is to feed the bottom of the food chain. In the case of a civilization that means that you lower the cost of water and energy.
The cheap energy side is coming in byo 4th generation msr reactors.
Ya gotta love the dweeb foundation knowing the greatest good.
