I was just reading that Dr. G Miley has produced considerable over unity heat after 4 hours, but his nanopowder deteriorates in short order due to sintering.
http://www.lenr-coldfusion.com/2012/09/21/george-miley-working-3kw-30kw-lenr-designs/ “Results were shown where the energy gain (LENR/chemical) started at about 7 after a few minutes, but increased another order of magnitude over four hours. Longer runs had problems due to deterioration of the nanoparticles, attributed to sintering.” This deterioration of nanopowder can always be expected whenever a static nanopowder is used in the LENR process. I wonder if Piantelli has the same problems with his nanopowder. Rossi avoids this problem by continually rebuilding his nanopowder after each input power pulse. This is the function of the “secret sauce”. I call this nanopowder renewal process “dynamic nuclear active environment” (NAE) formation. The “secret sauce” is an alkali metal like lithium or potassium: an element with a low vaporization point that first vaporizes and then re-condenses into Rydberg matter after each input heat pulse. These nanoparticles will eventually sinter but will always be renewed to provide a constant resupply of fresh nanopowder in a dynamic process. The function of the micro-sized nickel micropowder is to generate a Bose Einstein condensate which produces a superfluid condition that also protects nanostructures from sintering. >
