Great book! I've researched "free energy" for more than 22 years myself and this was the 1st book I could give to friends to explain the whole scene to them. It gives the history, like Tesla, Moray, Reich, Schauberger, and it shows you how big (and growing fast) the New Energy field is today. It also gives enough information for the researcher to direct his or her interests to the inventor that they wish to focus and further their attention on. This would save the researcher alot of time, as Jeane Manning has done all of the foot work for you in this book.
