Essentially they're different brands, AquaOptima and the system we used in our financial feasibility study. We had to start somewhere, so we chose the system based on the recommendations of a design consultant we had. There are various types and brands. AquaOptima is one, and there's another company in B.C. that produces large-scale research systems and components. As to the differences in capital costs, though, I think they would be negligible.
