Interesting article.

Call me when it works on an industrial scale.

Almost went to work for a guy a few years ago. He had a few patents and he managed to talk some venture capitalists out of $18M for a beta site project. I was going to run his industrial lab(s) and his QC program in return for peanuts and shares of preferred stock.
He was going to take materials from waste water plants and use it to make biodiesel. The material, such as skim from the aeration ponds is very high in fat content, but because of trace metals, etc., is hauled off to a hazardous waste landfill and costs the plants to do so. My guy thought he could get the material for free.
So, I talked his business plan over with my BIL (who is a very good ChemE), who said this idea would work great in a lab, but wasn't going to scale up. Simply too many variables. Also talked to some guys I knew on the technical side of DEQ and the EPA. I turned the guy's offer down.
My BIL was right.
