Superconductors might be macroscopic quantum gravitational antennas,
which can be used as efficient transducers for converting EM radiation into
G radiation ... and vice versa.

"In addition to its fundamental interest as an experimental testing ground at
the intersection of QM and GR, superconductors can be used as antennas and
transducers for an efficient and reciprocal coupling of electromagnetic and
gravitational radiation fields. A Hertz-like experiment is presently being
performed to test these ideas.
If this experiment is successful, superconductors can serve as the basis
for practical devices in gravity radio communications, especially
in light of the fact that all classical matter, including the Earth, is
essentially completely transparent to gravitational radiation.
An important follow-up astrophysical experiment would be to observe
the cosmic microwave background in gravitational radiation, as this would
tell us much about the very early Universe."
