The present video shows an excerpt of the testing of the commercial SunCell® design having refractory cell components and injection and ignition systems comprising molten electrodes engineered to last indefinitely.
First, the cell was operated with electromagnetic (EM) pump injection only…

Moreover, as designed, when the cell is operated as a silver boiler, the EM pump power may be terminated as well such that the parasitic load is zero except for the power consumed in electrolysis of water to provide the hydrogen fuel.
In fact, the power did persist at the same level for long duration after the ignition power was terminated…
