He compares his hose to a radiator, but a steam radiator at 100C emits heat at about 240 BTU/(hr*ft^2); see e.g. http://www.colonialsupply.com/resources/radiator.htm, or many other sites that talk about steam radiators. That converts to about 750 W/m^2 or .075 W/cm^2, about 14 times lower than he claims for rubber at 80 or 90C. (And what is it with Wh/h instead of the simpler synonym W?) 2. A 3-m hose, 2.5 cm in diameter, has a surface area of 3*pi*.025 m^2 = 0.235 m^2 = 2350 cm^2. His value is twice this. This seems unlikely, but not completely implausible, if the hose is really 4.5 m long, and really 3.5 cm (almost 1.5") in diameter. 3. Has he ever been near a 5 kW heater, used in heating machine shops and the like? The claim that hose emits 5 kW is too implausible for words. 4. In the video, Rossi says to Krivit, there is some condensation, but not much. Here he says there is complete condensation. 5. The pressure in the ecat cannot be room pressure, or the fluid would not flow out of the ecat into the room. (I wrote this a week ago, but did not realize it was off-list.)
