Unfortunately, it is virtually impossible to separate fact from fiction when reading this book. It is an excellent example of pseudoscientific writing - very entertaining if not taken too seriously.

Unlike active Tesla Coil hobbyists, Mr. Vassilatos has apparently never built or experimented with any of the wondrous devices he describes. Much of his writing about Tesla appears to spring from his imagination, not from Tesla's technical writing, patents, or lab notes. Mr. Vassilatos readily "reinterprets" what Tesla actually wrote to make it fit with his unique understanding about how Tesla Coils supposedly REALLY work. Unfortunately, he doesn't bother to differentiate between actual references and his poetic reinterpretations, so the reader is left to try to sort out fact and speculation on his own. Vassilatos' descriptions of Tesla's experiments, and in particular the operation of Tesla Coils and spark gaps, does not agree with the historical record (directly from Tesla), nor with experimental observation. His "theory of operation" for Tesla Coils is simply wrong. The "cold electricity" phenomena he describes does not agree with the experimental observations made (and chronicled) by Tesla himself, nor with experimental observations of countless Tesla Coil builders and experimenters over the past century.

There are many other, less expensive, alternative books about Tesla (such as those by T. C. Martin, John O'Neill, and Marc Siefer) that provide a more balanced, historically, and technically accurate description of Tesla and his works. And, they don't pack the conspiratorial sensationalism seen within this book.
