What if our existing solar panels are optimized to detect these? Then will it improve the quality of solar panels to capture more energy from sunlight as well? Sorry, I'm no expert in this - asking more of a curiosity.
Neutrinos interact extremely weakly with ordinary matter, which is why the detectors are typically huge volumes of water. Even then, the neutrinos interact with the purpose-built detectors on the order of one in a trillion. A neutrino power generator is not a feasible thing to build.
Unless you're next to an exploding star, in which case you have other problems/opportunities.

There's nothing to optimize here, neutrinos just interact very very weakly with anything else because they don't carry charge (so no electrical interactions), don't carry color charge (so no nuclear interactions), don't carry weak charge (so no weak force interactions) and have tiny tiny masses, but they are still bosons (so don't act as field carriers like photons do, they're just regular matter). Their low chance o…
> don't carry weak charge (so no weak force interactions)
Left neutrino have weak hypercharge, so they are produce by weak interactions and are detected using the weak interaction. And also gravity.
Right neutrinos (if they exist) have no weak hypercharge so they only interact by gravity.

#95For context, 120 PeV is about 10% the kinetic energy of a ping pong ball during typical play.
120 PeV is 0.020 of a Joule, or 20 milliwatt-seconds.

1500 watts is about what an electric kettle uses.
American kettles. Kettles in hard core countries push 2300 to 2400 watts ;-)
American stove startups can do it in 40 seconds with ??? watts by precharging a battery.

#97Ars Technica has an article, as well, with some additional context/explanation. https://arstechnica.com/science/2025/02/most-energetic-neutr... And an interesting, somewhat related, video from PBS Space Time exploring how supernovas act as particle accelerators (but don't quite explain particles like this one or the 'Oh My God' particle): https://www.youtube.com/watch?v=2sSNWIJbV3Q
Neutrinos “interact with regular matter so rarely that it's estimated you'd need about a light-year of lead to completely block a bright source of them. Every one of us has tens of trillions of neutrinos passing through us every second, but fewer than five of them actually interact with the matter in our bodies in our entire lifetimes.” They have 1/500,000 the mass of electrons. They interact only through the super s…
These rare interactions with matter are also a cause of concern in voting machines, right? Or at least it was a concern at one point. A random bit being flipped or something.

Next time I trip over nothing I am blaming those "darn neutrinos messing up my knee!"
The funny thing is a km^3 scale detector like km3net or icecube has roughly the same mass as all humans combined

Equally hilarious, the Kalgoorlie Super Pit has a volume of 3.15 cubic kilometers.
That's a single, albeit large, gold mining pit and a fraction of the even greater volume excavated by humans looking for shiny stuff.

Other types of particles interact much more frequently. But yes: bits do get flipped (even with ECC memory).
