In this question I've mentioned an account of the recently reported 2nd observation of gravitational waves, LIGO and Virgo Collaborations, Phys. Rev. Lett. 116, 241103, 15 June 2016, where 1 of the 22 solar masses is said to have been converted into pure energy - gravitational waves.
My question here is in two parts:
- Is there any standard theoretical framework where this energy could - in any way - transfer back to more "familiar" forms of energy, where "familiar" means mechanical, electrical, thermal... things less exotic than the energy being stored in the vibration of space itself.
- Is there any discussion of one way this might actually come about. Sometimes a theory that says something is possible doesn't by itself make it very obvious how it would be possible.
I'm looking for something carefully worked out and published, and not interested in any discussion of practicality.
