I have been following the fusion dream for over half a century. Ecat is a scam. All they have to do to prove it works is put a water jacket around the ecat unit and drive a toy steam engine with the heat it generates. No ecat expert has even proposed such a simple test. Same with this fusion device. Either show us some data/test results or keep quiet until you have some results to share with the world. Sorry for the negativity, but I have seen too many fusion breakthroughs in my time that never went anywhere.
Well, you have to give them credit for reducing the fusion reactor wait time from 20 years to 10.
For 32 days that single gram of fuel reportedly kept the reaction vessel 800 Celsius degrees hotter than the same vessel under the same conditions without the fuel, an energy equivalent of something like 45 gallons of gasoline from a single gram of fuel.
Unfortunately, the experiment is more complex than running a steam engine, though that would be a trivial extension. The problem is that the current E-Cat still requires electrical input for control purposes, so some energy is radiated without the E-Cat in operation. But the evidence shows that E-Cat radiates far more energy than its electrical input. The electrical input would provide enough input by itself to power a steam engine. The experiment shows that the energy produced by E-Cat would power several similar steam engines.
