comment Reproductibility of the effects described in US patent 8,419,919
I concur on current claims of cold fusion as a practical way to produce non-trivial amounts of energy. However the exposition in the patent I refer to does not describe any production of energy (much to the contrary: a lot is absorbed).

Clarify by removing "public", which was interpreted as "in front of an audience"

@CuriousOne: By publicly I meant: that can been reported; by opposition to classified. I'll fix the question.

Measurement of diameters with a caliper; report top speeds, clarify Q1.

comment What makes a wrist-energized gyroscope rotate faster?
I have added the diameters of shaft where it is rolling (2.5 mm) and washer (60 mm), now measured with a caliper. Yes, the spinning rate of the rotor is about consistent with the hypothesis (which I take as fact) that the shaft is rolling on the casing. After some practice, I am now convinced that the "right" movement of the casing to spin-up the rotor is one that presses the casing on the rotor, in a way such that friction tends to increase the spin rate, rather than slow it down (which occurs when the casing is left idle).

comment What makes a wrist-energized gyroscope rotate faster?
@user3058846: when something gains speed by friction (in some Galilean referential), in all examples I know, this is thanks to something with a faster speed (in that referential). As tentatively explained in the updated question, I do not see that this is the case here, at least if I consider rotation along the rotor's axis (which, admittedly, is not speed gain in a proper Galilean referential; perhaps what I perceive as a paradox comes from that).
