Eric, Yes it is. Something interesting is taking place here.
I watched the video again. There was a subtitle that might resolve some of the issues: "Measurements showed heating 7 liters of circulating water for 180 seconds. In the air by 2 degrees. Under a hydrogen atmosphere (1 bar) by 3 degrees." I calculate an average of 326W output in the air condition and 488W in the hydrogen condition. Input powers were reported as 129Vx3.5A=452W (air) and 129Vx3.4A=439W (hydrogen). It does appear there was greater output than input in the hydrogen condition (at least during that 3 minute period).
