The previous results related to excess energy seem to been explained by completely fraudulent demonstrations. Electricity and heat were made from hidden connections to conventional sources.
On January 31, 2019, Rossi's released a new product called E-Cat SK via live video stream. The product is reported as currently available to be leased by factories as a source of heat. Tom Casten and Australian physicist and aerospace engineer Ian Bryce said that the inputs, outputs, and measurement points are not defined. Ian says the results are meaningless.
The latest claim is a new product called E-Cat SKL. This is an E-Cat SK that has electricity generation and the output electricity used as input for a continuous reaction. The new claim is that the system can have energy used to start it and then it will run continuously far beyond any chemical processes.
