For the Origin of Free Energy (Paperback)
Review of your book is simple. On your theory (considering your mathematics formulas) I say nothing, I am not mathematician. On the free energy ideas, I prefer to discuss engineering aspects of real devices, experimenting and testing. So, the book is useful if it include some value ideas and schemes for experimenting. Your book is useful. Good book - Alexander V. Frolov "Free Energy & Antigravity Technology" Russia.
