One curious detail which sounds crazy but is worth a passing mention is the physical similarity of the experiment to the design of Stanley Meyer's device. Has this ever been mentioned before?
This experiment uses two closely spaced brass tubes, one of which is plated with iron. The results are said to be due to anomalous ionization. Galvanic corrosion is not emphasized as the operative effect. The surface effect of confined gases could also be a factor also not emphasized. There is little proof of anything nuclear. Consider the Tesla turbine disk, with its spacing of 0.5 mm which reportedly provides the highest efficiency in another device where surface effects are seen. That is, there is an optimal disc spacing distance in the turbine device which could be related to this whole picture of a non-chemical energy anomaly. Of course, this spacing is much larger than the Casimir geometry but that effect could somehow be involved in a derivative way, With Meyer's device, if - IF - there is also anomalous ionization due to geometry alone - that is - of closely spaced electrodes, and ... if this net electrical charge somehow makes it to the combustion chamber to aid in the hydrogen burning then the answer could be in some dependence on the actual spacing within the physical structure itself. Who knows? Maybe Grimer's beta atmosphere is involved ... Jones Jed Rothwell wrote: See: Di Stefano, A.
