I got what I expected right on the first page-- King refers to his belief that our planet has been and is regularly visited by alien spaceships. Anyone else who does should should read Carl Sagan's "The Demon Haunted World" or any of his work. That aside, there is a growing body of scientists who have serious doubts that the Quantum and Relativity theories will ever yield the most complete explaination of physical reality. Some of these other physical theories are based upon the behavior of what is known as the zero point field, more or less as put forth by King in this book. Unfortunately, this book is a collection of essays taken from his lectures over the years, outlining his quest to convince inventors to build free-energy machines. At no time does King discuss past successes, or presumable failures, of the experiments described in his earlier lectures, so his particular theories seem to be fundamentally incorrect.
