This has been "going to happen" since, at least, the 1940s. At least once a decade someone reinvents the idea and creates a lot of interest. Then it dies again for a while.
The entire power grid is an RF choke. RF over the power lines works until it gets to a transformer. That's a good thing because it reduces impulse noise which can play havoc with electronic equipment. Fast rise time impulse noise on power lines is a problem in electronic equipment and instrumentation.
