I think you should call the heater an ionizer instead of a cathode, because where there is a cathode there is normally an anode. > >The minimum cathode material that could generate hydrogen ions is tungsten. >Usually, thorium is alloyed with tungsten to increase electron emissions.

I think he said that on his blog. Of course, Rossi may be trying to hide the fact that he using a heater wire made of tungsten. who knows? Harry
