"...the filter described in this paper also allowed them to recover valuable resources by selectively separating carbon dioxide from nitrogen...."

That could be very useful!

If they found a really cheap way to separate H from O in H2O, that would be super useful.

Not going to happen with a filter since energy has to be used to split the H from the O, but there may be lesser energy tactics using these kinds of filters.

First you have to separate the H2 from the O.
Then split the H2 into H and 2.
Finally ending up with an H, a 2, and an O.

Better still, split the 2 into 8 quarters, so there's more for everyone.
