Good point, I didn't even pick up on that slight bit of nonsense. Anything
above 374 deg C and your out of luck. The fourth power law did cross my
mind, however that's why I think the 30% number, like most other hydrogen
crap we hear is pure fantasy. It's interesting too that  these hydrogen
articles keep poping up in the popular press while the scientific and
technical press is much more reasoned.
