This is another reason why the output flow should be collected. > I think this refers to the Jan. 14 test. What Rossi is saying here is that they left the reservoir on a weight scale (as you see in the photos), and they measured the total reduction in weight over the course of the run. This method is as good as collecting the output flow. You could not easily collect the flow in this test because it was steam. Probably a mixture of steam and hot water by the time it reached the sink. The only way to collect is would be to sparge it into a tank of cold water, which you weigh before and after. You also measure the temperature of the tank before and after to determine total enthalpy. As I said at the time, I wish they had done that. But it takes a lot of effort and heavy containers of water. It is easier to do in a factory using a steel drum and fork lift, which is what they do at Hydrodynamics. After the test, they drive the steel drum full of ~80°C water out into the parking lot and dump it. It is kind of dangerous. - Jed
