I think that you would have more than a few problems collecting neutrinos for experimental purposes, Antonio. For one thing, neutrinos have zero electric charge, and while there is a claim by Japanese researchers that some evidence exists for their mass, the question of their mass is generally left dangling in the same dubious thought balloon as that belonging to the photon. Neutrinos participate only in weak and gravitational interactions and are therefore very difficult to detect (Gravitational interactions between fundamental particles are 1/(10^29) smaller than the weak interaction). Neutrino detectors have been built, but they cost billions of dollars and they only occasionally detect a neutrino but cannot capture it. The only way that I can see that they can be collected in the amounts required for experimentation purposes is through controlled thermonuclear reactions utilizing a type of acellerator that separates these particles from a fission or fusion reaction, if we could think of a way to actually do that. The critical mass required for a controlled reaction of the type that would make the collection of neutrinos possible makes this exercise really quite impractical. But that is not to say that it would be impossible, but better left to the realm of science fiction for the time being.

So the right answer to mkirkpatrick's question is really:

No, we would need a neutrino factory of sorts.
