Observers were allowed to weigh the hydrogen gas container before and after the experiment (weight: 18.6 kgs). Even considering possible errors in measurement (duct tape still attached), hydrogen usage was estimated at less than one gramme, not enough to make conventional hydrogen combustion plausible.

'''Inconsistencies:''' Not only was the duration of the experiment with 20 minutes shorter than the claimed duration, but there are also reasons to doubt the other claims of the inventor and operator of the experiment. The estimation of energy by evaporation of water was criticized in "www.physicsforums.com" in retrospect, as respective calculations were made based on dry vapour without fractions of condensed water which was not proven. The probe shown in the video can only measure the heat but not the dry condition of the steam. It was claimed that a combined probe of the type HP474AC (Delta Ohm) was used but in the video a different probe, which looks like a SPC C45 0500 BEX - probe, can be seen. The throughput of water claimed at 29 mls/min. (= 17.5 liter/min) was doubted, too, as the pump used had only half of this capacity according to specification. It is obvious that a pump of the type "LMI J5" was used. The manufacturer gives a maximal flow of 7.6 liter/h.<ref>http://www.lmipumps.com/Files/lmi/Global/US-en/site_files/seriesj5.pdf</ref>
