I have a drunken plan involving sending neutrinos through the earth as a form of communication. Friends inform me that it has only three problems: producing the neutrinos; modulating the signal; and detecting it at the other end. I shall continue pottering.

Atomic bombs produce large bursts of neutrinos, which should be sufficient for the Super-Kamiokande detector in Japan. Amplitude modulation is possible through Dial-a-Yield and MIRV warheads can convey multiple bytes. Environmental impact may rival Bitcoin though..

That’s surprisingly similar to my build-a-laser-to-traverse-the-core-and-then-beam-financial-data-through-it. Current state of research: my remote cousins in New Zealand and I have made a “planet sandwich” by laying bread on the floor of our antipodal dwellings.

Nuclear reactors produce neutrinos and they can be detected [1]. For modulation, maybe vary the reactor power output (low bit rate, to be sure). People have explored neutrinos for communication with submerged submarines [2].
