Well, it's nice to see that I'm not completely crazy ;). I'm happy to see, however, that the article pretty much sums up why this isn't actually a feasible solution.<p>In addition to the extreme bulkiness of both the emitter and detectors (See Super Kamiokande), neutrinos only really get generated in certain particle decays. This means you're pretty much stuck with needing a nuclear reactor (of varying sizes) to generate them. Although this alone isn't necessarily a problem, it's really not something governments are going to be overly happy with garage hackers doing. :(<p>Can the detectors be sized down? Maybe. Unfortunately, there's a good chunk of inherent randomness in neutrino particle detection. It may be that there's no good way to actually detect them short of brute force: Big detectors, lots of neutrinos, and just playing the odds.<p>We can dream though. And investigate.
Misleading headline. No one is thinking seriously about building a neutrino network. As the article mentions at the end, the detector has to be massive and the transmitter uses a great deal of power.<p>There would need to be an extraordinary breakthrough in our ability to detect neutrinos before something like this would be practical.<p>Neat trick and impressive that they could make it work at all, though.
This isn't the first time this has been thought of. A particle physicist had suggested nuclear submarines be laced with scintillators so the could receive messages sent by neutrinos a while back, which seems like a somewhat feasible, practical use of this technology.
"Instead of traveling 10,000 miles or more via cable, it’s only 8,000 miles in a direct line through the center of the Earth."<p>8k vs 10k -- is it such a big difference? I see it more as cost efficient -- "powering up" 10k miles long cable may be more expensive than shooting a "beam" through the Earth.
Maybe it would require a little less energy, if instead of generating our own neutrinos, we modulated the neutrinos that go throught the Earth from sun - no nuclear reactor required, "just" a huge fast moving lead block :)<p>EDIT: also - what happens, when neutrino passes event horizon? Because maybe we could modulate neutrinos stream using very small black holes :)
Do I have this right? Neutrinos are fermions, carriers of mass, and therefore have no wave characteristics in the two-slit experiment sense. Seems to me that "neutrino radio" is a misnomer?
here is a thought: center of the earth is 6,000c hot. There is a heat resistant aluminium to withhold this temp. Further, I am sure there are solutions to generate electricity from the heat. I wonder how hard would it be to dig a hole through the center of the Earth and put the cable in it, hahah :)
