woodworker everybody was expecting it to be a test but Rossi did a demo of how he plans to connect his future reactos to future control box.
During the demo, the device connected to the power outlet produced measurable heat using unspecified amount of electricity.
There was also a handsome swedish speaking physics to give a show a bit of credibility and sweeting the pill for those who paid money from the trip.
I think it is fair to call it a demo.
