Two more Mylar bag variants, designed to eliminate the risk you mentioned of damage to equipment in case of Mylar breakage:
1/ Seal, as a second barrier against leaks, using an O ring, a gasket, or glue, of inconsequential composition, the CR-39 watertightly to an open cell wall, e.g. to the bottom of an open tube as I suggested below, and line the entire inside of the cell with a Mylar film. 2/ Use a normal cell with unopened walls and bottom, put the CR-39 chip inside it, on its floor or against its wall, and then line the inside of the cell with Mylar. What's new with the bag designs we just discussed compared to Earthtech's is that the Mylar bag contains the electrolyte, rather than the CR-39 chip, so that the back of the CR-39 is free for whatever detector/instrument one cares to stick against it, except variant 2 above. But the latter still has the advantage of an optically clear path to the CR-39, without intervening electrolyte. ----------------- Now something which has nothing to do with implementation details. If neutron tracks are consistently found in these experiments (which we don't know yet do we?), I for one would be interested to find whether they persist if we leave some water space between the cathode and the plastic rather than putting them in contact. If they don't persist, in spite of the thin water space being essentially transparent to neutrons, it will mean the contact of the cathode with the plastic promotes the LENRs won't it?
