Graphene sieve turns seawater into drinking water

Agelbert NOTE: PLEASE, spare me the, "but, but, you need fossil fuels to make graphene" argument. What you NEED is ENERGY. And there are MILLIONS of places on planet earth that you can HARVEST that (RENEWABLE) energy for an on location graphene factory that does not use ANY fossil fuels, EVER!

You also need Energy to make the water cross the membrane, because you are reversing Entropy, (there is more Entropy in seawater, a mixture of water and chemicals, than there is in pure water here and a bunch of chemicals there).  In the desalination efforts currently up and running, that Energy is input by applying pressure to the seawater with electricity-power pistons.  The cost of the Energy to do this makes desalination plants in Australia (Brisbane and Sydney) too expensive, white elephants - used only during extreme long-term droughts.

So the third world is never going to get fresh water this way.

The Palloy reading comprehension difficulties, AGAIN. This new desalination filter will NOT require PRESSURE, either osmotic or otherwise. THAT MEANS that there will be ZERO energy REQUIRED for the separation of the major part of the ions from the H2O.

If you had a grasp of biosphere math, enzymatic catalysts in nature and all the various shortcuts the biosphere uses to avoid the STUPID and inefficient HEAT, BEAT and TREAT method humans prefer due to a preference for brute force approaches (as if THAT ruinously energy intensive approach is "IT" in thermodynamics - it's actually the WORST approach!), I would discuss this issue with you.

But since you are routinely deliberately obtuse and selective in the way you measure the COST of energy invested to run processes in civilization and energy returned from those investments (UNETHICALLY DENYING the Social cost of Carbon CONTINUOUSLY), I have nothing but pity for your inflated self confidence in these matters.

You do not have the remotest idea of what you are talking about. Have a nice deluded, ARROGANT, CLOSED MINDED, DAY.
Rob not the poor, because he is poor: neither oppress the afflicted in the gate:
For the Lord will plead their cause, and spoil the soul of those that spoiled them. Pr. 22:22-23
