Hallo, I stumbled upon in the internet a very simple method for doing extremely accurate (up to two or three significant digits, depending on insulation) calorimetric analysis for any water boiler. Method is simple and all measurements are accurate:
– Just weight 5 kg water into bucket. – Measure the temperature of water. (preferred temperature is the same as inlet water temperature) – Put hot water/steam outlet hose into bucket for 5 minutes. – After the experiment, weight the water in the bucket and measure the temperature change. – To refine accuracy, after the experiment, observe for 5 min how fast 70°C water is cooling. This gives accurately the amount of heat outlet hose is carrying with steam and hot water. It is sad that Mats Lewan did not realize this simple to do calorimetric method. If he had realized this, he would have observed ΔT to be around 30-40°C and this would have spared us all from lots of excess heat generated in discussion forums. This is also strong argument that sloppy science in E-Cat demonstrations was not Rossi's fault, but those independent observers, such as Galantini, Levi, Lewan, Kullander & Essén, could have just pointed out this simple and accurate calorimetric method, if they had been smart enough. But instead Galantini, Kullander, etc. performed irrelevant measurements when they tried to measure wetness of steam, although it is well known fact that all water boilers on Earth produce ca. 98% quality steam (±0.015), in normal pressure. –Jouni
