I`m a researcher and author on topics ranging from the history of North Korea`s nuclear program to the history of U.S. intelligence. So I often come across patents for uranium, plutonium, nuclear reactors, heavy water, etc. I`ve been published in DCBureau.org, the KPA Journal, NKnews.org, and the American Intelligence Journal four times. My current project is a book on Dr. Fritz J. Hansgirg (who died in 1949). He holds more than 30 patents from hydrogen production to magnesium production. My co-author is Dr. Kenneth N. Ricci, a nuclear physicist from Stanford. The title of the book is Dr. Fritz J. Hansgirg: Heavy Water and the Secret History of the Atomic Bomb. Half the book is history and the other half is filled with discussions of Dr. Hansgirg`s various patents. Profile ©
