It might be just what we need to power an Alcubierre drive. I'd probably want them to research this kind of energy source for at least 200 years before trying something like that, though. We wouldn't want to wipe out the solar system by accident.
I'm totally with you there. If we are going to do it we should be doing it on purpose.
Potentially useful even if Alcubierre drives turn out to be impossible after all.
