Not for that particular neutrino, it's gone. But yes, my home (and yours) is being heated by neutrino power as we speak. It's not a significant enough amount of energy to make a dent in the utility bill however.
Most inefficient thermal power plant possible: utilize the difference in neutrino flux between the hemisphere that's open to space vs. the hemisphere where Earth is in the way.
But now I'm wondering what percentage of the useful thermal power in a nuclear power plant is produced by the neutrinos created in the reactions (the infinitesimally small fraction that happen to interact with the matter within the reactor, that is).
On the contrary, it would have to be efficient indeed to do anything useful underneath all of the shielding that we'd need to keep those baser forms of radiation at bay. Gamma rays: yuck.
