if you're trying to build a transmitter for gravitational waves, say a spinning metal rod, remember: emitted power scales only with the square of the mass but sixth power of frequency

@rjukan
So you should take e.g. a neutron star, if you can get one?
@sten yeah, but the mass distribution of a neutron star is fairly invariant under rotation, so you'd need at least a binary system of neutron stars revolving around their gravitational center
@rjukan so, not a brilliant idea for e.g. telephony purposes then? :-(
@rjukan Dammit, and I thought I could trick my local phone company by making free calls to Proxima Cantauri.
