Is this new ? I know pot-holers in the UK who've been playing with this kind of stuff for years.

Given how long ago Tesla died, I'm guessing that it's not new :-) I do suspect it's relatively new as a commercial proposal, as opposed to homebrew.

Tesla was a smart guy, who made major contributions to electrical theory, but he was also wrong sometimes. Like he trusted Edison....

. Sounds vaguely like VLF and ULF communications - with much shorter antennae.

Hmmm... how much would this cost? Because instead, they could just get radio signals to work underground...

I guess you didn't bother to read the linked article. Too bad.
