— Terrence "Nick" Gildred

"I was sure HYDROGEN Hot Stuff Cool Science was going to be a stodgy and tedious read. I discovered, to my delight, Rex A. Ewing has concocted a formula that made it not only educational and informative, but downright entertaining. It's a winner!"
— Dennis Weaver, Actor, Ecolonomist, Founder / Board Member - Institute of Ecolonomics

"I have read nearly every book on hydrogen technologies, and can safely say that this is the most readable and entertaining book available. If you're looking for a comprehensive treatise on the technical aspects of the hydrogen future, I highly recommend this book."
—Doug Larson, Ph.D., owner of FuelCellStore.com

"This unusual book takes an innovative and engaging approach to teaching a general audience about hydrogen. HYDROGEN – Hot Stuff Cool Science is an ingenious achievement, making complex scientific concepts digestible for the motivated lay reader. PixyJack Press is clearly onto something good."
—reviewed Richard Engel of Schatz Energy Research Center for The Hydrogen & Fuel Cell Letter

"This book will be a real asset for teachers attempting to illuminate the multifaceted science of hydrogen energy. I give Ewing an A+ for originality!"
—Raymond Atwood, High School Science Teacher, 2003 Western North Dakota Teacher of the Year

"What a great book! If there's a way to make science interesting, this is it."
—Steve Iwanicki, Jr., High School Senior

"Using a wise wizard capable of bringing the hugely important new science of hydrogen energy to life is a clever approach, and every chapter is followed by technical details obtained from excellent web references. Readers are in for a lot of surprises—including many amazing, not-yet-well-known future approaches to hydrogen generation and use."
—Ronal Larson, Ph.D., Chair - American Solar Energy Society

"It will appeal to readers of any age who have not lost their imagination or spirit of adventure. I also recommend it to the journalists, economists and political leaders of our age in hopes that they will get the science correct when they speak of the most serious technical problem of our time."
—Richard S. Treptow, PhD, retired Professor of Chemistry - Chicago State University; textbook editor for numerous publishers

"Science teachers will love "technistoff," the technical notes and references following each chapter. Armed with these, teachers can enrich their own knowledge and understanding of some incredible new technologies of hydrogen generation, storage, and delivery, as well as visiting some very instructive web sites with their students. HYDROGEN - Hot Stuff, Cool Science is at once a very enjoyable read and super resource for teachers, as well as for the lay public, who are looking for ways to sort out the basics of hydrogen science."
—Dr. Charles Bottinelli, Disney American Teacher Awards Honoree, 1999; Colorado science educator for 39 years

"This book will take you from a hydrogen illiterate to a person with a great working knowledge of all that is hydrogen. Rex has an uncanny way of using a spoonful of sugar to make the medicine go down."
—Larry Cooper, Kyocera Solar
