    "...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.
