Single circuits generate nuclear reactions

Actually it has to do with h2o and gas molecules I believe.

?This observation led to the discovery that the lubrication is due to the presence of fluids between the layers, such as air and water?

the layers can?t slide.
Moisture must be part of it?s lubricating quality.
I?m working on something a bit different than here though,
Very thin graphite on dielectric. Resistance,thermal noise, tunneling.

Do you mean vacuum? That's to be expected as in vacuum graphite crystallites should stick to each other making it a "rocky" substance that will actually block any movement.

Graphite powder should be the best thing to use. Simply pack it into a PVC tube, close with two metallic caps and fire discharge through it.

Only difficulty is finding something to contain the powder,

One could try concrete tube or something like that as well: you may create a concrete tube yourself by using two PVC tubes of different diameters. Just cook some concrete mix and pour it between the tubes, then let it dry. Probably use some lubricated paper in order to be able to remove PVC tubes later.

hmm, my brother has just got himself a kiln, thin clay tubes, i'll see him tonight.

interesting read about silicon carbide, when heated the silicon evaporates away and whats
left re-forms into graphite, maybe have better alignment within the graphite.

The layers of graphite slide past each other because the delocalized pi electrons above and below the planes of the graphene crystals exhibit electrostatic repulsion with those of neighboring crystals.  This electron configuration is also largely responsible for the conducting properties of graphite.

Graphene crystals are practically superconducting along their edges.  The effective mass of the charge carriers is essentially zero, owing to the overlap of the conduction bands of electrons and holes in reciprocal space.  An energy barrier must be overcome for current to flow between adjacent crystals.  Electron tunneling between crystals may be accompanied by electromagnetic radiation, as in the Josephson effect.

The laser analogy seems appropriate, since to get a net EM wave from an applied current, coherence must be established for the tunneling current across the band gap.  "Stimulated emission" seems like a good candidate for explaining a superradiant EM output from an applied current in graphite.

haven't built any circuits for about 20 years now, but spent a few quid on parts, assembled everything crammed 12 volts into it with me scope on the output to test it and voila !!!

nothing...............

i did expect it to go 'pop fizzle' the way i make things, but it didn't, just got a constant +12v with no pulses.

i probably used the wrong caps, has anybody got a 'foolproof' parts list so i know exactly what to get?

i know, sorry guys (i can hear you sighing from here  ). i'll take a piccie of my setup and post it in a minute, its worth the effort to get it up and running, i think so anyway.
