In one of the last appendices (#35) to our recent Report #3 on Andrea Rossi and his energy claim, we wrote about a videotaped demonstration of Rossi’s device by Mats Lewan of Swedish magazine Ny Teknik.
Lewan approaches the bucket and the hose. No steam is visible or audible. Two seconds later, it is. Lewan goes back to the main room, and his camera shows Rossi with his hand near the power controls. The power was supposed to be constant during the test.
