It's also possible to transmute Hydrogen into Helium.
The big glass tube on the right is a vacuum capacitor. The black coil around the sealed electrode-less H tube is the output winding.
I discussed this with him in the past, on a private list. Change in the color indicates presence of He. He said he could get an output voltage from the properly tuned black coil even without any input, as if the fusion was spontaneous. But he never would divulge the frequency he uses.
