Here’s another historical video provided to me by Craig Cassarino, former partner in AmpEnergo, an early licensee of Leonardo Corporation.
This one is from 2010, in the days when the E-Cat was a heater, and shows Andrea Rossi demonstrating an E-Cat system to various visitors. I am not sure who all of them are, but I was told that one of them is Dave Nagel who has been a long-time champion of LENR/cold fusion research.
In this video Rossi answers questions about the test protocols from his guests and shows data collected on an oscilloscope.
