Oh boy, now he's talking about rocket fuel. My only thought is that he must have gotten an A in advertising (bovine scat) class. Hydrogen is hydrogen. The element is pure. There is no way for the molecules to combine, and have an attachment point for an impurity. Basic, high school chemistry stuff. And rocket fuel? The shuttle still uses Hydrogen and LOX, no changes. NASA also uses other hydrocarbon based fuels in other spacecraft as appropriate, but not because of "the fire incident", which was, BTW, a defect in the solid booster.
Add me and WC Fields to list of sceptics. "If you can't dazzle them with brilliance...."
