A video from the ICCF20 conference in Sendai, Japan has been uploaded to YouTube of a presentation Michael Halem of LENR-Invest, LLC, reporting on his experience trying to validate the Brillouin Hydrogen Hot Tube (HHT)
in an experiment carried out at SRI headquarters in Berkeley, California.
Michael Halem has commented below, and has made this correction: “The experiments were carried out at two locations: 1) Brillouin’s HQ labs in Berkeley and 2) SRI’s lab in Menlo Park. The rigs were substantially the same, but environmentally, SRI’s lab was better temperature controlled.”
His goal was to find out if the HHT was indeed producing excess energy as claimed.
His presentation gives details about the design of the reactor, the calibration he carried out (using helium instead of hydrogen in the reactor core), and the results with a fueled reactor.
He says that he is “90 per cent sure” experiment was producing about three times as much energy as was being input into the system (12 to 20 Watts of excess power.)
Halem does disclose that he says that he invested in Brillouin Energy for his company, LENR-Invest.
UPDATE: (Oct 18, 2016) Michael Halem has provided some additional detail on the experiment:
The ICCF20 talk is a synoptic version of the paper which will be published around the end of December in JCMNS:
The heat produced by the experiment is calculated from a calibration fit of temperature vs. power output using a two coefficient model (k_c, the conduction+convection “Newtonian” coefficient, and k_r, the radiation “Stefan/Boltzmann” coefficient). The heat is supplied by either a resistor, or by a reaction, hypothesized to be LENR. The flow rates of the Ar cooling gas on the experiment are so low that almost all of the heat is dissipated before the gas gets to the heat exchanger. The calibration does not rely on a measured quantity of heat removed by the heat exchanger, but rather by the total heat removed by the experiment from conduction+convection, and from radiation at different temperatures.
A future experiment, to commence shortly, will work to remove the irregularities that I noted in the previously experiment.
