well if these papers are legit (and that seems to be a big if) then you should be able to build a "box" with one open end that blocks enough neutrinos to be able to distinguish the ones coming in from the open end of the box. (I think.)

(I think.)Where are you getting that from?Well, IF these results are to be believed, 32Si has an absolutely astonishing neutrino interaction cross section. So just use 32Si to make the walls of the box (you may also want to add a layer of lead to keep the stuff from decay 32Si away, but that does nothing to neutrinos). Then have another unshielded (by 32Si, you can encase it in lead if you want) clump of 32Si as your detector.
In relative terms, maybe. But we're talking about a fractional increase in decay rate, in the face of a truly enormous solar neutrino flux (something like 10^10/cm^2). And even then, the neutrinos are unlikely to be absorbed or scattered through large angles, because then the energy transferred to the decay products would be far more diagnostic - that's why we can detect them with Cherenkov light. The idea that this process is "blocking" neutrinos is way out there.
http://phys.org/news/2016-11-solar-physicists-easier-peculiar-particles.htmlif this is real then (eventually) why not a high resolution neutrino "camera?" one that would have applications for studying the interiors of planets and stars or used for nuclear treaty verification or targeting a nuke in flight even? i know the neutrino environment is the one with the most noise possible but there could be processing techniques that could filter out all the noise. what if the advancement of technology eventually yields a micro or nano scale detector?
