  High energy neutrinos are produced by the annihilation of dark matter
particles in our galaxy. These are presently searched for with large area, deep
underground neutrino telescopes. Cold dark matter particles, trapped inside the
sun, are an abundant source of such neutrinos. Back-of-the-envelope
calculations are sufficient to demonstrate how neutrino telescopes are
competitive with existing and future particle colliders such as the LHC in the
search for weakly interacting massive cold dark matter particles. We will
emphasize that a $1\,\rm km^2$ area is the natural scale for a future
instrument capable of probing the full GeV--TeV mass range of cold dark matter
particle candidates by searching for high energy neutrinos produced by their
annihilation in the sun. We speculate on what such a detector may look like.
