Well - yes - the theory is falsifiable in exactly this way, but of course - you only do mass spectrometry on the hydrogen fill not the entire device.
And yes - at least I have heard that SRI has an instrument sensitive enough to do this kind of measurement on hydrogen - but for whatever reason, it is not in use as of this date. It would indeed take a very sophisticated piece of equipment - as the proton mass on average will not go down by more than a fractional percent following a long gainful run, like the 50 hours of Celani. From: [email protected] Energy comes from proton mass depletion So... the way to test this theory is to weigh the thing before & after the experiment? Does any LENR researcher have equipment sensitive enough to detect the difference in proton mass depletion?
