Yes- I looked it up after I read your post! It is now on my "to purchase later" list on Amazon. I love stuff like that! Too bad the original divers who discovered it couldn't keep their mouths shut!

Re Tesla- I was introduced to him back in 1992 by a dear but eccentric friend in South America. The things he told me about are only now becoming part of mainstream knowledge about him. It's taken a long time for a bad smear campaign to give way to what he was actually up to! Brilliant, brilliant man.
