Actually, as far as I know, Hal Puthoff was not involved in the measurement. The Griggs test was done by well-grounded engineers. This was the same team responsible for development of the MOAC calorimeter. When I heard how they measured the actual mechanical power going into the pump, I was impressed by the sound basis of their measurement. Many other Griggs tests were based on motor electrical input power measurement with estimates for the motor electrical-to-mechanical conversion efficiency. I think it was a reasonable presumption that it was the hydrosonic pump itself that was potentially overunity, not the big electric motor. So, Earthtech measured the pump.
MOAC itself is well grounded in basics. One of the core difficulties in a flow calorimeter is accurately measuring the flow. Most researchers try to use volumetric flow measurement - which is a mistake. The heat capacity of a milliliter of water varies with temperature, dissolved air, and entrained bubbles. MOAC measures the mass of the water flowing because the heat capacity per gram is nearly constant. Mass flow measurement is hard to implement, but they went the extra mile to make that kind of measurement. That is also the way the calorimetry was done at SRI as I understand it. <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> Virus-free. www.avg.com <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=webmail> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Fri, Aug 6, 2021 at 9:50 AM Frank Grimer <88.fr...@gmail.com> wrote: > I wouldn't worry too much about Puthoff > > Puthoff took an interest in the Church of Scientology > <https://en.wikipedia.org/wiki/Church_of_Scientology> in the late 1960s > and reached what was then the top OT VII > <https://en.wikipedia.org/wiki/Operating_Thetan> level by 1971.[3] > <https://en.wikipedia.org/wiki/Harold_E._Puthoff#cite_note-Urban-3> Puthoff > wrote up his "wins" for a Scientology publication, claiming to have > achieved "remote viewing <https://en.wikipedia.org/wiki/Remote_viewing>" > abilities.[4] > <https://en.wikipedia.org/wiki/Harold_E._Puthoff#cite_note-4> In 1974, > Puthoff also wrote a piece for Scientology's *Celebrity* magazine, > stating that Scientology had given him "a feeling of absolute fearlessness". > [5] <https://en.wikipedia.org/wiki/Harold_E._Puthoff#cite_note-5> Puthoff > severed all connection with Scientology in the late 1970s.[6] > <https://en.wikipedia.org/wiki/Harold_E._Puthoff#cite_note-6> > > On Fri, 6 Aug 2021 at 16:30, Bob Higgins <rj.bob.higg...@gmail.com> wrote: > >> Hi Jones, >> >> I now have Earthtech's MOAC (calorimeter) in my lab and I am refurbishing >> and re-commissioning it.
