The key lies in interacting with many, many neutrinos - again, as produced
by the sun, for example.  Though I suppose the energy you'd have to put in
for this example probably well exceeds the energy you'd get out - and for
sailing applications, you could just sail the non-neutrino parts of the solar
wind, as has already been demonstrated.
