Recently retired and now consulting privately. After earning his Ph.D in chemistry from UC, Berkeley, and studying Electrochemistry as a post-doctoral at the University of Pennsylvania, Dr. Tanzella worked as a chemist at DuPont. Since 1986, he helped develop the low energy nuclear reactions (LENR) electrochemical and calorimetry program at SRI and hosted many other LENR researchers in attempts to reproduce and understand their processes and devices. Dr. Tanzella gives his account of the evaluation of the Brillouin HotTube, and how that relationship will continue despite the closing of SRI's LENR lab.
