Here is a further comment about the Mizuno heater and its possible non-obvious functionality.
Think of the heater as a IR light source. The heat is actually not the purpose so much as the photons, which may be close to coherency at the best setting. IOW the “heater” may server the same purpose as a filament on an incandescent lightbulb and the “light” in question is in the IR range and semi-coherent. There ha been a lot of speculation over the years that plasmon/polaritons play a role in LENR. Brillion was promoting this plasmon/polariton at one time but they have not been able to show anything near as exciting as the Mizuno. This may also be the reason for the very low pressure fill – maintaining the coherence ! From: Jed Rothwell I asked Mizuno what sort of sheath heater he uses. He uses a 500 W model, such as the Flexible heater "M2 type micro heater"
