The casing enclosing the reactor was opened after completion of the test, and the invited guests was thus able to see what was inside – basically a heat exchanger with metal flanges; within it, according to Rossi, was a shielded flat reactor unit with three reactor chambers, only one of which was operating during the test.
Highlight so the Mats Lewan Nyteknik report
The E-cat model used in this test was enclosed in a casing measuring about 50 x 60 x 35 centimeters. As in previous tests heat was supposedly generated inside a reactor by a reaction between nickel powder and pressurized hydrogen in presence of unknown catalysts.
Water was fed into the E-cat from a peristaltic pump and heated to boiling temperature. The steam at the output from the E-cat was fed through an insulated hose to a heat exchanger where it was cooled down and condensed while heating a secondary circuit of water. The cool water from condensed steam was led through a hose down the drain.
Water from a tap was fed to the secondary loop of the heat exchanger. The heated output water was led through a long hose to a well outside the building.
Water temperature at the input and the output of the secondary loop was measured with thermocouples attached on the metal connections at the heat exchanger where the hoses were attached (see video) and the difference in temperature was used together with the value of the water flow to calculate the output power.
To start up the reaction and reach equilibrium, electric power was fed to a resistance inside the E-cat for about four hours, interrupted only by short intervals of self sustained mode.
The E-cat was then put in self sustained mode for almost four hours, showing no measurable signs of weakening.
The E-cat casing opened, showing the heat exchanger supposedly containing a shielded flat reactor body consisting of three reactor chambers.
After three hours and a half, output temperature inside the E-cat was stable about 114 degrees centigrade, and water could be felt boiling putting a hand on top of it. The external temperature was between 60 and 85 degrees centigrade.
At the end of the test, the heat production was slowed down by eliminating hydrogen pressure and increasing the water flow from the peristaltic pump through the E-cat.
After cooling down the E-cat, the insulation was eliminated and the casing was opened. Inside the casing metal flanges of a heat exchanger could be seen, an object measuring about 30 x 30 x 30 centimeters. The rest of the volume was empty space where water could be heated, entering through a valve at the bottom, and with a valve at the top where steam could come out.
Inside the heat exchanger there supposedly was a layer of about 5 centimeters of shielding, and inside the shielding the reactor body, supposedly measuring 20 x 20 x 1 centimeters and containing three reactor chambers.
According to Andrea Rossi, only one of the reactors was in operation during the test.
Weight of E-cat before test: 98 kg after test: 99 kg Weight of heat exchanger before test: 10.208 kg after test: 10.265 kg
Hydrogen was filled after having checked that there was no pressure inside the E-cat. The bottle was attached, opened, closed, and detached.
Weight hydrogen bottle: – before filling: 13606.4 grams – after filling: 13604.9 grams Total loaded: 1.5 grams
Pressure H2 Bottle: 55 bar Reduced: 15 bar
The accuracy of the measurements during this test must be considered fairly low.
Still, the measurements should lead to the conclusion that this model of the E-cat produced heat at a power of at least 2 to 3 kilowatts in self sustained mode, in this case supposedly with only one of three reactors inside the casing in operation.
As a heat exchanger was used in this set up, steam quality had no importance for the calculation.
The self sustained mode that went on for over three hours, also seemed extremely stable and showed no measurable sign of weakening.
It can also be noted that after three and a half hours of self sustained operation water could still be felt boiling inside, putting a hand on top of the insulated casing. The surface temperature of the insulation was then between 60 and 85 degrees centigrade, meaning that a significant heat loss must have decreased the power output through the steam and the heat exchanger.
