Paul and I tried one of these on the you-know-what. It even puts out three phases and can be wired for others: http://www.thebackshed.com/windmill/FPRewire.asp > We never measured the efficiency; but, it was far less than the CSIRO motor at 98%. Other modified Halbach arrays claim as much as 99% generator efficiency. If money was not an impediment, I would purchase a CSIRO motor (99% eff) and Halbach array generator and mount them on a common drive shaft so as to serve for a test bed for certain claimed OU devices. The most efficient of these Halbach arrays seems to be in the 1-2 kW range - but needs to be in a narrow rpm range, but this could be accommodated. Thus - a device for testing, like the Manelas device which required electrical power from a battery and returned electrical power to recharge the battery - which is crux of many claims - could be tested with low losses, even if a transformer and inverter needed to be added. Cree has a nice 98+% eff inverter, and specialty transformers are in that range. With that kind of test bed, it should be possible to close the loop with anything over COP 1.2 electric-to-electric, like the Bedini, Newman and other claims. Even if all four losses were considered (motor, generator, transformer, inverter) this should close the loop. As for electric to thermal and then back to electric, that has always been the problem. Mills hopes to solve this with photovoltaics. The wild card would be the Qu-tube, which is said by the inventor (Dr. Qu - of course) to be a thermoelectric diode and capable of moving current with heat flow. http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20080009660.pdf I had the suspicion last week that the 3 of the 6 alumina tubes of Rossi could be operating as Qu-tubes (left side which is cooler) despite the claim for AC - and that the end cap on that side was acting as an electrical diode, but would have been detected.
