That is quite true; to date the ECAT only produces heat. But what of that? That’s what oil, natural gas, coal and nuclear power plants do to generate electricity. They produce heat, and the heat is used to generate electricity. So it’s a no-brainer that the ECAT can produce electricity if it produces heat. It’s just a bit of engineering to do so efficiently and in useful packages (such as in vehicles or home residential, as well as in big commercial applications.)
There is heat then there is heat. I think the demonstrations have produced wet steam, perfectly fine for making hot water or heating a house be almost useless for generating electricity. If this gizmo is for real, there is still a ways to go before it is ready to spin a generator.
