The pressure of the hose is too small, in another thread I wrote this : Considering a stream of 10m/s, 1.5g/s out of the hose, with, 5cm2 of area, the pressure inside above 1atm the chamber is P=F/A=(1.5*10(-3)*10)/5*10(-4)=(1.5*10(-2)*10(4))/5=1.5*20=30N/m2 or and increase of 3*10(-4) atm. It

Just to be sure of my position. I am completely convinced that the data that has been provided is coherent with a power generation of 2.5KW. My doubt is from where the power is drawn. Rossi does have control over the current, using his computer, so he can surely change the power while cheating on

The appended response appears to be nonsensical. Perhaps it is due to a language barrier? The calculation provided appears to be meaningless. It appears to *assume* a priori a free flow of steam, i.e. no percolator effects, no pressure or flow variations. Also, it would be more

As for the Krivit's test, there is nearly no condensation inside the hose. That is visible in any of the video. The water output due vapor doesn't require a very fast flow, so it is certainly free, with no turbulence. The kinetic energy is just too small due vapor, 0.2W.

The output temperature and flow output, even visually, are convincing. They are visually equivalent to putting off a candles by blowing them, that is 0.2W - 0.4W. But to make it only by heating water and vaporizing requires more than 2000KW. I don't think the con comes from that. If that was so

But 2KW does give a very feeble buff, unless it is ousted in a very thin cavity and accelerated by propellers, like in a hand vaporizer.

It won't change much. I used 1.5g/s which gives 3.300W, so, 1.8g/s fits the bill. So, it is just a slightly stronger blow.
