Active Solar Collectors and Their Applications Book

Extremely well studied and well written, the grand history of generations of hydrogen research and hydrogen mass implementation struggle. so many failures, setbacks, fading to oblivion, getting nowhere, etc. but still going on.Not like many other kind of books with the author having a biased and cheerleading mindset and using examples which just supports his /her idea, without mentioning or intentionally eliminating the final dead end of the quoted examples in its final shapes, Mr. Peter Hoffmann's quite objective, but also effective, not by misleading or say luring you into a believer, but by show you the whole picture, including the failed struggles and setbacks, thus give you a much clear and down to earth view about Hydrogen. I strongly recommend this book for anyone who interested in hydrogen or general sustainability and energy issues.
