It is a long story. The Hydrodynamics gadget produces heat by generating ultrasound. Under some circumstances it appears to produce anomalous excess heat. Many years ago they invited me out to see the gadget because they knew I was involved in cold fusion and they suspected this might be some form of cold fusion. The heat was confirmed with various tests at their factory and also at customer sites. These tests included large-scale flow calorimetry with liquid water and also steam which was sparged into a 50 gallon steel drum, as I mentioned. The company spent a great deal of money constructing an industrial scale flow calorimeter, which was designed by the Dean of mechanical engineering at Georgia Tech. This calorimeter confirmed the excess. I think it is very likely the excess heat is real but I have no solid widespread replications or other rigorous proof of that. As I recall, the machine typically transferred around 90% of the input electric power to the steam or hot water. That is when nothing anomalous or unusual is happening. When it was producing anomalous heat, the steam had roughly 110% to 120% of the heat from the input power. That would be many kilowatts of excess heat but it was only a small fraction of the total output and it had no commercial significance. The company found that discussing this anomaly only confused the customers and made people suspect they were up to something, so they have stopped making the claims. - Jed
