The scramjet is actually powered by hydrogen (from a fuel tank) oxydized by atmospheric oxygen.

*laugh* I didn't read that far in the article, but that's pretty funny. Maybe the author got the scramjet confused with a Bussard Ramjet, which is a theoretical rocket design that scoops interstellar hydrogen as fuel for a fusion reactor, thus negating the need to carry any fuel.
(obviously, I'm kidding - the author was definitely science-illiterate... the day somebody invents a jet that doesn't require any fuel, just let me in on the IPO).
