Wow this sounds too hard to believe, but it looks she's talking about Tom Bearden as the unnamed engineer. http://gemspheres.com/faq/
I'm going to have to look into this more.
Also the link you provided for the "Battery Output Lab Test Data - pdf" seems to be bad. The link says it's at CZ, but goes to the Rense site and can't be found. They probably moved it? This one is working right now I know. http://rense.com/general96/Battery%20Research.pdf
