So many levels of wrong, fractally wrong, or as Pauli would say: "not even wrong".This is complete utter nonsense because it totally ignores the elephant in the room of the effects of ejecting matter in the form of rocks through the Earth’s atmosphere amounting to around 3 x 10²¹ kg to account for the total mass of asteroids and the mass of the impactors causing craters in the solar system.
Heat is produced by:
(1) Atmospheric friction on projected matter from ground level where heating is pronounced as the atmosphere is at its thickest.
(2) Friction caused by deformation of ground where water is ejected.
(3) Inelastic collisions between matter creating heat.
(4) Air being compressed by the motion of flying matter.
(5) Re-entry of matter into atmosphere causing friction heating.
O look, another level of wrong. Walt (what is it with "Walt"s?) would have been better off on this point picking an ancient quartz crystal oscillator and going full New-Agey. (Both the far-out Christians and the political right, and especially where they over lap, sometimes sound like they all escaped from a Californian ashram in 1983, a bit "crunchy".)Quartz (SiO₂), is a common mineral in granite and piezoelectric because it has a particular crystal structure which is asymmetrical and allows mechanical stress to generate an electric dipole moment.
Granite is a polycrystalline aggregate of multiple minerals (quartz, feldspar, mica) with random orientations which cancels any piezoelectric effects.
And the nonsense continues. Free neutrons only have a half-life of 10-15 minutes.
Half-life 10 minutes (base 2) mean lifetime (base e) 15 minutes (rounded to nearest minute).
For the heaviest (and therefore most neutron-rich and generally less stable) elements, the issue is about how quickly the nucleus beta decays *after* absorbing the neutron and before capturing another. If the the typical neutron capture rate results in only a single capture before the nucleus decays again, then only isotopes close to stable isotopes can form (the slow neutron capture process in stars). To get to the really heavy nuclei many neutrons must be rapidly captured *before* any decay happens (the rapid neutron capture process). This takes a hundred or more on neutron captures on a single nucleus in roughly one second.The reason why neutron capture occurs to produce heavier nuclei is that an enormous number of free neutrons are required from neutron star mergers and supernovae to make it statistically possible for heavier elements to form within the short time frame of a free neutron’s existence.
Wasn't it neutrons emitted from the neutron star that became our Sun? (jk)This also includes statistical outliers for neutrons with anomalously long half-lives.
Where is the source of free neutrons on Earth to react with hydrogen to produce deuterium and radioisotopes; the irony is if such a source were available the Earth would have been obliterated in the process.
OK, let me try again. Let see we could capture protons on carbon c12(p,g)n13, beta decay to c13, then alpha capture on the c13 to get a free neutron c13(a,n)o16. Oh, no, wait, that's how AGB stars do the s-process.
Water does make a good moderator. The neutrons can bounce around until they are slow enough to stick, or if they don't make a neutron-sludge at the bottom of our under ground caverns. Oh, wait, how do the neutrons make it through the layers of granite without capturing on Si, O, Mg, Fe, Ca, Ti, etc. in the rock?Then there is something called the reaction cross section which is the probability that a neutron and the hydrogen nucleus (proton) will form deuterium. The reaction cross section for deuterium is extremely low for one of the reasons given the binding energy is only 2.2 MeV. To put this in the simplest language the binding energy is not high enough for the proton and neutron to have a high probability of ‘sticking together’.
I think Walt might be trying to break the record for wrongness. Let's check with Guinness. (... nope, got a bit to go yet)The deuterium found in the universe is overwhelming primeval in origin as the conditions immediately after the Big Bang of high density and temperature favoured its production.
The idea of deuterium formed in subterranean chambers is so ridiculously wrong.
