Bests & Worsts Reviews from Amazon

As an engineer who both uses hydrogen and can work the math, I'm astonished that no one has corrected Peavey. He mixes units, get equations wrong and just plain can't spell. A decelerating engine is "braking" not "breaking", for example. His thermodynamic computations are often wrong once you work them out, his "borrowing" of other sources is painful where "propane" was not changed to "hydrogen" is all cases in a paragraph. Incredible. This text is very nearly the "Anarchist's Cookbook" of renewable energy -- there's a lot of words, some of it correct, but someone's going to get badly hurt if they actually follow this guide. All that, and a decade out of date to boot. If Amazon would take the book back, I'd gladly send them the ashes from the woodstove.
