This book reads like an advertisement for several of Patrick Flanagan's inventions. The author keeps referring to him as a Doctor, but I am struggling to find evidence that he ever achieved a Doctorate. I believe his inventions are real but I'm dubious about the claims made about them. I was hoping this book would help me to verify any of the claims, but it does not. Instead it just touts the unverifiable anecdotal rhetoric. The author fails to cite references, studies, or anything of practical value about Flanagan's work. I bought the book thinking "Dr. Flanagan" was a real scientist but I finished the book questioning everything about the man.
