Regarding the content of the book, it is a well thought out expose of the possibilities and limits of sustainable energy and I highly recommend it. However in the preface, the author states, "This is a free book. I didn't write this book to make money. I wrote it because sustainable energy is important. If you would like to have the book for free for your own use, please help yourself: It's online at withouthotair com."



Naturally, I wasn't very happy about paying $30+ for the Kindle version.
