I understand that you need not my explanations.
As you on a threshold of great discovery.
But nevertheless I will explain you if I wish how I would swindle lop-eared amateurs.
• 750W electric input heats up an empty jacket.
• At the same time water with flow 2g/s begins enter into jacket.
• 450-500W is enough for heating up all entering water to 100 Celsius deg.
• Remaining 250-300W will evaporate only part of entering water.
• Remaining water will slowly fill the jacket.
• For avoiding the filling I would install at the bottom of jacket a simple and small drain valve with very small hose.
That’s all, finita la commedia, my little quantum tunneling friend.
Your tricks could certainly be used by someone trying to deceive, at least for a briefly witnessed demonstration. But, the steam output as a portion of the total water output (what percent is vaporized) introduces such a large difference in the true output, that manipulating this factor alone is enough to explain the claimed excess energy, without the need to use other deceits or unexplained physics.
ChrisMB's qualitative demo suggests that this may indeed be the the case.
ie, input heat, water flow rates and measured temperature may all be legitimate. It is the claim that (almost) all of the measured temperature is from dry steam, not a small portion of steam mixed with hot liquid water that can explain the discrepancy.
ChrisMB's demo certainly highlights this discrepency. Also, in the video, he pointed out that Rossi appeared to drain the tube before removing it from the sink drain fits with this picture of hot water draining through the tube with some relatively small quantity of steam bubbling/ percolating through the liquid.
If ChrisMB better quantitates his steam flow and heat input, the steam production claims of Rossi becomes increasingly indefensible.
As mentioned by others, actually quantifying the steam vapor flow by collecting it in a bottle (displacing liquid water) for a modest amount of time, and then demanding that Rossi do the same would fully expose the stupidity or fraud of the machine. It would remove the possibility of misleading steam production claims.
As has been pointed out repeatedly, this is a flawed setup an any case. There is no reason the water flow should not be increased till the delta T is some manageable number (such as 30 degrees C ) where phase transitions are irrelevant. Even course measurements would then suffice to prove or disprove the large heat gains claimed.
As you point out, other deceits still need to be eliminated if the device passes this basic and very easy test.
To error is human... and I'm very human.
