*How is it possible that the black tube is laying quiet on the ground while the steam has a high velocity of about 300 km/hr. The high velocity of the steam would create a reaction force in the tube which would cause the tube to change position. The diameter of the hose, was underestimated so the velocity is closer to 80 km/hr which is not insignificant but consistent with results *Further the escape of the steam from the black tube would create a very hard noise, which would attract the attention from people. Same overestimate applies to lack of noise - not expected. *Why has nobody noticed the extreme velocity of the steam when the steam quality was measured with a probe ( deafening hissing sound)? Again, there was no extreme velocity *Also I would expect that the black tube ( which looks like a waterhose) would soften because of the high energy content of the steam. 101 C is easily within the range of most rubber and plastic. In the end - and even if all of the problems were there as claimed, the heat demonstrated by Rossi is still a factor of 10 times input (instead of 20-30 x). Extreme thermal gain seems to be a non-issue, except in the extent of gain. Jones
