content: A research paper from lirpa-tsrif university proposes using solar neutrinos instead of photons to collect energy from the sun. Just 19% of the suns energy is emitted as visible light, the remainder is distributed across the electromagnetic spectrum with the majority in the infrared band. Around 3% of suns energy is carried away by neutrinos and it is these which the paper proposes using.Normally neutrinos do not interact with matter, it would take many lightyears of lead to stop them. However, this is only true for ordinary matter made from up/down quarks and electrons. So called Gen2 matter, made from charmed and strange quarks along with the muon, could catch 80% of neutrinos in a few mm. These normally unstable particles would be stable within the confines of a Gen2 atom in exactly the same way that a neutron is stable when part of an atom. A free neutron has a half life of 14 minutes.Calculations indicate a solar neutrino hitting a Gen2 carbon atom would pump a muon to emit a near ultra-violet photon on the way down. These photons could be converted to usable power with a conventional solar panel. The paper proposes a deposition layer of Gen2 matter over Gen1 silicon panels, but stops short of indicating how this could be achieved in practice.Ref: Solar neutrino panelshttps://www.lirpatsrif.edu/dideye/getcha/solarneutrinopanels.pdf

content: I wonder if that material might unexpectedly end up very toxic. Asbestos was considered safe due to its chemical inertness until a lot of workers exposed to it started getting sick.

content: Quote from: woofy on October 20, 2024, 07:17:35 pmHe does point out that the technique only produces tiny amounts of power, and isn't going to deal with more than very specialist applications. There are a lot of remote monitoring applications that just need a tiny amount of reliable power, without using batteries that have lifetime issues. Whether this technique will produce enough to even meet those needs is open to question, but if you can focus things in some way, so the panel is only looking directly upwards, the temperature differential you have is between the cosmic background and the temperature of the panel.

content: Quote from: woofy on March 31, 2024, 11:05:10 pmSo the short version is that instead of trying to capture 19% of the sun's energy, we should be attempting to capture the 3% that can not be stopped by any currently known substance.Who comes up with this shitt?And what about the other 78% of the sun's output?

content: We already know the properties of strange and charm quarks bound together (strange D mesons): They have a half life of half a picosecond. All other strange quark containing particles have similarly short half lives, none above a few nanoseconds.
