uh ... the cross section has nothing to do with the de Broglie wavelength! the cross section measures the probability of absorption precisely (roughly the probability is the product of the cross section, times the density of absorbent particles, times the length crossed).
It's wrong :
"
De Broglie wavelength is an estimate of the wavelength associated with particles as a function of the energy of the system. If the characteristic dimensions of the system (crystal lattice, average volume, average travel distance, etc.) are greater than the De Broglie wavelength, the wave interference effects can be neglected and the behavior of the particles can reasonably be studied at using the laws of classical mechanics. Otherwise, the interference effects between the particle waves make it necessary to use quantum mechanics to study the physics of the system.."
that's what I'm saying, the cross section has little to do with the de Broglie wavelength ... your extract does not say the opposite (for example in the extreme case "hard sphere" and if lambda << R the cross section is constant (Pi R ^ 2) and INDEPENDENT of lambda).
This means that a particular mesh (which perhaps graphene could provide), depending on the type and energy level of the neutrino to be intercepted, can promote coupling with it, in particular via a plasmon whose electronic oscillations would resonate with the neutrino's "matter wave".
but no, a structure like graphene is a structure based on electromagnetism, like all chemistry. And the neutrino not being charged does not "see" this structure.
Moreover, resonance phenomena are by nature narrow in frequency, so if an amplification existed, it could only concern particular energies, and the higher the resonance, the narrower it is, and the fewer particles involved. As much as they are important for transmitting information on selected frequencies (which is the case for radio where precisely one transmits at precise frequencies and one tunes the receiver on these frequencies), they have no impact on a continuum where most of the energies are out of resonance.
This is also the principle of interference filters which are used for example to "visualize" the Halpha frequency in the sun, precisely because the continuum is off (pretty images there for example;
http://www.astrosurf.com/luxorion/image ... -ha-fr.htm )
But natural neutrinos have no energy peak ... so a possible resonance would have no effect.
Your assertions are far too simplified and categorical for them to be claimed to demonstrate impossibilities.
I repeat that
a) if an electrical power could be extracted, it would first manifest itself by a perfectly measurable heating - and that would be known
b) if a phenomenon like that existed, there would be plenty of scientific publications that would already talk about it. And there is not one.
Me, that's enough for me to bet how much you want this thing to be whole custard, at any rate. For example, I'm ready to bet you € 10 that no publication will come out on it within a year, that I will pay you if there is one that comes out, against € 000 that you pay me if they don't come out.
100 €, that's always what you win
