Wonder if one could make the membrane out of something like stainless steel to support higher pressures now that we know how this process works

- bmelton 3y agoIgnoring the "how impossible is it to drill 0.2nm holes in anything" conversation above for a moment, what do you get out of stainless steel? My gut tells me you're looking for something with more permanence, but even stainless steel seems like a bad choice for something whose job requires constant contact with salt water (ergo, rust)

- fwlr 3y agoSupporting higher pressures or higher flow rates through the same area is one way to scale up reverse osmosis, but it requires some serious engineering to do (from the discussion above, very nearly at the “controlling placement at the individual atom” level). Meanwhile another way to scale it up is just make more of these membranes that we know how to easily make, and have bigger areas of membrane.
