He patented this five years ago.[1]  Here&#x27;s the 2015 paper.[2]<p>Flow rates are very, very low. Note the reference to the fluid source being a &quot;Harvard Apparatus Syringe Pump&quot;.[3] That&#x27;s just a motorized device for very slowly pressing the plunger on a syringe, for very low flow rates. If they&#x27;re using that after five years of work, the process is still limited to very low flow rates.<p>This is not necessarily a killer limitation. Reverse osmosis started that way, but has been scaled up to industrial scale.  But the technology is not here yet.<p>[1] <a href="http:&#x2F;&#x2F;www.google.com&#x2F;patents&#x2F;US8801910" rel="nofollow">http:&#x2F;&#x2F;www.google.com&#x2F;patents&#x2F;US8801910</a>
