I dunno. But given the excess heat findings in these types of experiments, the energy generated is orders of magnitude more than what is available through chemical processes. So, extracting the Deuterium becomes much less of a concern.
Well, if you believe this BS that is your business, but I will only believe it when I actually see a car driving around on a gallon of water. Even a small working model would convince me, but they will never have one because they are full of sh**.
