I would be nice to know how this stuff compares to current RO material. Isn't there a basic amount of energy required to desalinate water, that you can't do it for less?

True, you have to overcome the osmotic pressure, which would be the same for current RO membranes or these new types. This is where the bulk of the energy is used. Reading the article I don't really get what improvement is made with these membranes. One the one hand the article claims a high flux for the new material, on the other hand fouling, stability and mechanical strength seems to be among the problems to solve.
