People wonder why Levi has not given out more information about the 18-hour flowing water test. I wish he would publish a detailed report listing the type of flowmeter and so on. It is annoying to me that he has not.
I expect Levi and the others consider that test irrefutable. So do I. If I had been there observing that test, I would have glanced at the outlet thermocouple reading, put my hand on the outlet hose for a moment, and then I would have been 100% absolutely certain there is massive excess heat. I would have had zero doubt, to 5 significant digits. No matter how far off the flow meter or input power meter may be, you could not get a temperature difference large enough to feel unless there is tremendous excess heat. A quick glance at the flow rate and the size of the inlet electric wire would have told me that the temperature difference from input power cannot be more than 0.1°C no matter what. I would have dismissed any questions about that result as amateur foolishness. I expect that is how Levi feels. It would be like this scenario: Guy drives car into repair shop. Tells mechanic: "Something is wrong with my car. It doesn't steer straight." MECHANIC: "That's 'cause you got a flat tire. Your right front's flat." GUY: "Are you sure that's the problem?" MECHANIC: "!@$%## Of course I'm friggin' sure!" To take another imaginary example, a guy gives me today's weather report in Japanese, which happens to be: 九州北部地方では、１４日の日中は気温が３５度以上となるところがあるでしょう。熱中症など健康管理に注意してください。 I tell him it is for northern Kyushu and it says beware of heat-stroke. GUY: "Are you sure this is a weather report and not a love letter or something about an insurance claim?" ME: "Of course I'm sure, you nitwit! I was translating stuff like this 20 years before you were born." Rossi's attitude towards Krivit is similar. In the video, Rossi did a rough approximation of the heat balance on a paper chart. I am sure that result is correct as far as it goes. I expect it is no more than 10% or 20% off. That has no effect on the overall conclusion. This is fundamental physics going back hundreds of years, long before they invented RH meters. The heat of vaporization of water at ~1 atm is fixed. That is definitely steam coming out the end of the pipe. The blabber that Krivit raised and that has been repeated here about RH meters is irrelevant even if it is is true -- which I doubt. Rossi may have over-reacted to the criticism. I could have told you he would. No one is perfect, and he tends to be thin-skinned. Krivit probably knows this, and may have provoked him. (Ya' think?) I sympathize with Rossi. It is irritating when an amateur lectures you about a subject you know far better than he does. You can be darn sure that Rossi knows more about heat than Krivit does. Or than I do. He may not know much about RH meters but he never claimed to. You don't need one to measure enthapy when you are only aiming to make a rough approximation. - Jed
