That's what I was thinking. They have sent neutrinos from one lab to another with a man-made source and a detector smaller than 1km^3. The idea is to put a strong source in orbit and aim it at an orbiting detector. Over time this configuration would be used to scan the entire planet. Still a huge challenge.

That's essentially the main idea most people come to. Using a source so you can concentrate on specific ones and not get distracted by solar, cosmic, or terrestrial neutrinos. Or you could just use terrestrial ones. But still, that detector is the hardest part to figure out.
