23) With a series of papers on AIP proceedings Dott. Fontana has developed the fundamental concepts for building the gravitational counterpart of the LASER.

This unique effort is described in the paper High Temperature Superconductors as Quantum Sources of Gravitational Waves (HTSC GASER), that includes the most important references. Besides any possible criticism related to the real existence of Gravitational Waves and the fate of ongoing big science experiments, all interested scientists and funding sources and organizations should carefully read the paper.  

This is Leon Brillouin’s dream that is going to become real:

“Radio was at a standstill until amplification was invented by De Forest; optics progressed slowly until Townes invented masers and lasers were built by Kastler. Who will now build a GRASER, a powerful amplifying device for gravitational waves?”
