Unless those neutrinos are left over from the big bang, the neutrino flux is about 80 W / m^2. This is what we get from the Sun. The neutrino flux from Stars is proportionate to the light flux, and since the light from the Sun vastly outweighs the light from the stars, the neutrino flux from our Sun must also vastly outweigh the combined neutrino flux from the stars. Ergo, the neutrino flux is not "extremely large", in fact it's only about 8% of the energy we receive in the form of Sunlight, and we are better off using solar panels, the more so since we know how to do that, while trapping neutrino energy is a complete unknown at present. The only advantage to trapping neutrino energy would be that it is available 24/7. Even so it would need to be done cheaply with near 100% efficiency, and this seems extremely unlikely given the incredibly low cross section of neutrino interactions (given that they are only available 24/7 because they pass through the Earth almost unhindered).
