Dave,
It would be nice to get Infinity Turbine to donate a few weeks of testing time on their ORC device which had been modified with a DC generator driving a bank of Ultracaps. The caps would be sized so that there is maybe 15 minutes of cushion in the energy storage – but no batteries. Cree makes a 3-phase inverter that is 95+% efficient from DC. With this kind of setup the penalty for both storage and DC/AC conversions would be low – less than 10%. With 6:1 gain and 21% OTC efficiency at 600C, there could be just enough to close the loop. Jones Here is the Cree demo of high efficiency DC/DC. As I understand it, DC/AC is at least this good or better http://www.youtube.com/watch?v=o8F4s86d7PY From: David Roberson It will take more than just a generator and an extension cord to close the loop. Some form of energy storage will be required to do the job. From: Jones Beene The reputed gain is so high – Rossi would be wise to forego calorimetry and go directly to conversion of heat to electricity. Here is the device that could do that – ORC in a small format. This device is perfect for the HotCat. http://www.infinityturbine.com/ORC/IT10_ORC_System.html At 6:1 gain, Rossi should be able to close the loop. From: [email protected] Even though I'm still wearing my skeptic's hat (that's the one with the propeller on top) isn't the argument about the need for calorimetry made irrelevant the amount of energy observed to have been generated? In other words, even with more precise measurements the exact energy output couldn't have been something more than an order of magnitude lower which would still validate the claim of significant over unity energy output.
