[Valkonen’s] post seems to be utterly out of touch with reality, a total fantasy. It is shocking to read. I don’t know whether to respond or not.
The claims made for months that all the water was being converted to steam has been utterly crushed!
Krivit was clearly right on his seven points.
More importantly, the claim that all the water was being converted to steam, the repeated, defended, and heralded basis for thinking something practical has been created, the basis for the “calorimetry” of the public demos, is now shown to be without basis in fact. The hose was taken off. Water pulsed out of the outlet right at the exit of the E-cat in large quantity. It obviously did not condense there. The water trap was clearly undersized by more than two orders of magnitude! It was less than useless! That I assume was because it was never dreamed the flow of water would be so large. What an embarrassment that must be.
The fact that the steam that comes out with the water is dryer than the water that pulses out with it is irrelevant. It is a red herring issue, a distraction from the glaring truth, a distraction from attention on the months of wrong headed excuses for not doing calorimetry on the output, and failure to *do* anything useful, other than talk, to see if the claims being made were true. So is the issue of the definition of steam quality. The important fact, that all the water is clearly *not* being converted to steam, clearly demonstrates just how bad the prior “calorimetry” claims were.
Now the new E-cat never reaches equilibrium. This is a far more difficult regime in which to do accurate calorimetry, and a far better regime for self deception. Further, the E-cat mass has been greatly increased, and the max input power increased. The “heat after death” from mundane causes will now obviously be much longer. The thermal mass is larger, and the thermal resistance from the outside of the lead to the water is much larger. It will make for a dandy magic show, and much more discussion, but will make actual evaluation of the value of the device much more difficult.
None of this indicates for sure whether Rossi has anything of value or not. Maybe he does. The continued failure to obtain independent high quality input and output energy measurements prevents the public from knowing. Since the public is being kept in the dark, the months of fluffy bluster does, however, tip the scales more strongly toward a negative verdict. What a pity and waste of valuable time this is for Rossi if there really is something extraordinary going on in the E-cat. Hopefully the 1 MW unit test will provide economical steam for a very long period.

I watched Mats Lewan’s NYTeknik video of Rossi’s latest E-Cat demo — Heffner is right, this videotaped result (large amounts of liquid-phase water pouring out of the E-Cat’s output ‘port’) is a catastrophe for Rossi’s claims of huge excess heat production.
If Rossi’s claims were true, then there should have been little or no liquid water present in the E-Cat’s output stream.
What is actually observed in Lewan’s video clip are copious streams of liquid water with some admixed steam; if that’s the best device performance Rossi can demonstrate as of today, his little charade is over.
As far as supposedly demonstrating “heat-after-death” for 30 minutes, the device itself is hidden behind tinfoil and (presumably) underlying insulation. If the E-Cat’s reaction vessel has thick stainless steel walls, it could easily have substantial intrinsic thermal mass. An input power of 2.5 kW of heating for a while would transfer thermal energy into the steel vessel walls (i.e., heat them up). Depending on the E’Cat’s total intrinsic thermal mass, cool-down after the power is cut-off could easily take 30 minutes. Therefore, what was demonstrated in that video doesn’t prove anything with regard to there truly being any excess “heat-after-death.”
Sadly, this is yet another very poorly designed and instrumented, horrendously sloppy, experimental fiasco that proves nothing other than the technical incompetence of the people that designed and executed the so-called experimental ‘test.’

The stomach of the Fat-Cat can hold around 30 kg of water and at start-up it was empty. With a pump flow of 15.8 kg water per hour it takes about 1.4 hours to fill up the Fat-Cat and the warming starts after half an hour when 8 kg of water has been pumped into the cat.
After 2.5 hours a temperature of 100 C is reached and by then the cat has been full and overflowing for 1.1 hours. Now boiling starts, but the temperature is still increasing, up to 133 C. This may seem odd because it corresponds to a pressure of around 3 bar. But the explanation of this is evident when Mats removes the steam / water exit hose and you can hear the new sharp hissing of the Fat-Cat: there is a flow restriction in the exit. This restriction causes the pressure in the Fat-Cat to increase in relation to the steam / water flow.
When the electric heater is turned off there is around 30 kg of water with a temperature of 133 degrees Centigrade and 33 of these can be used for boiling water during the so called “self-sustained mode”. How much steam that actually was produced during the half hour that the Fat-Cat was running without heating is anybody’s guess because nobody had the good sense to perform CONDENSING CALORIMETRY.
The Fat-Cat show was ended by closing the input water valve and removing the feed water tube. When the valve was opened over a bucket, water with a temperature of 122 C and with a pressure of about 2 bar was leaving the Fat-Cat. The overheated water boiled momentarily thus lowering the temperature to 100 C and the produced steam gave the spray high speed and generated a very loud hissing noise.
It would appear that the only reason for the transformation of the the E-Cat into the Fat-Cat would be to pull the above described stunt off.
It should be pointed out that this supposed design of the Fat-Cat would be subject to safety regulations that apply to a pressure vessel that contains an overheated fluid. 30 kg of water with a temperature of 133 C at 3 bar poses a deadly threat to any bystander.
