overhead power lines aren’t intentional transmitters but some form of “could i power a device from the RF leakage?” gets asked on EE stack exchange at least once a year since its inception. it’s hard to point at anything in the press release and confidently say “that’s new”. i think what’s happening is that IoT/sensing is a big enough market that companies can finally invest in engineering and commercializing some of the things that have been researched over the last several decades. which imo is great to see.
