Well, generally speaking, in the world of elementary particles there may be other kinds of interactions (and decay paths) as well as the good old mechanical energy - all waiting to be converted into the electromotive force.

Are there new types of interactions underway that may make neutrinos interaction feasible?

A hypothetical idea is to direct a neutrino beam at the core of a pulsating star, which modulates its frequency and allows for efficient interstellar communication.

Thing is, neutrinos hardly interact with anything at all, we need huge sensors just to detect a few signals once in a while so they would be na horribly inefficient way to capture energy.
