There's probably $1.5 billion in the ground already in neutrino
detectors; the total combined detector bit rate is pretty poor.  One
experiment looking at neutrinos coming off the Fermilab accelerator
had 473 million accelerator pulses with under 1.1 million detected
neutrinos.

Note that each pulse was probably millions or even billions of neutrinos, so
the detection rate was even worse than you'd think.  I saw a statistic that
every second, 50 trillion neutrinos pass through your body.  And the number
that will interact is well into the single digits.
