Ann: EdenCrete Field Trial in GDOT New Highway Project, page-41

If I'm using production cost of hydrogen then all of that that is accounted for already. Except for water, surfactants and the mixing process to create the final additive. Its still a very comfortable margin at USD25/gal and USD75/kg CNT, and I would think in line with quite a lot of industries which see markups of over 400% between cost of production and retail sales price.

Personally I think over 50% of the revenues will be profit, and it could be as high as 80%. The 20-30% figures that have been suggested are probably very conservative. I think mine would be more consistent with the funding proposed for plant expansion.
