I may be incorrect, but I suspect that Rossi has never conducted a long term experiment in public because he does not have a controller that functions well. Everything that has been observed during the public demonstrations has been manually controlled. The self sustaining mode is merely a way to eliminate the need for a controller. The driven mode would require feedback operation where the duty cycle of the power input waveform was controlled and/or the water input flow rate would need to be under electronic valve control. To use feedback effectively, several sensors would need to be accessed.

And if they really had success with own experiments in sustained eactions, then it is not understandable why they need Piantelli & Rossi. Do they possibly play a secret service type fudge-obscure-confuse-spread rumours" game to protect their currently ngoing actual research? Im happy to support them ;-) Am 10.11.2011 20:41, schrieb Mary Yugo: http://blog.newenergytimes.com/2011/11/10/nasa-engineer-explains-why-rossi-demos-failed/ "According to a slide presentation given by NASA engineer Michael A. Nelson, which New Energy Times obtained under a FOIA request, “Energy Catalyzer” inventor Andrea Rossi failed to conclusively show that his device produced excess heat from a nuclear energy source. According to Nelson, a NASA engineer who investigates low-energy nuclear reactions and space applications, Rossi did not run his demonstration long enough to prove his extraordinary claim. At the Sept. 22, 2011 LENR Workshop at NASA Glenn Research Center, Nelson explained that Rossi “would need to run [his experiment] for eight hours or more with a small E-Cat and much longer for an Ottoman [Fat-Cat] to rule out a chemical reaction.” According to Nelson, it would take “three or more days for a small E-Cat, two or more weeks for an Ottoman [Fat-Cat] E-Cat and several months for a 1 MW plant.” The slide and more at the link.
