I can’t find that quote in the article—or anything that definitively indicates they’re talking about RF power rather than RFID signals (other than saying the transmitters “power up” all the switches, which could just be sloppy terminology.)
Sorry. Yeah, that's not a quote from the article. Just just something I went and grabbed elsewhere real quick to explain rf power.
The article says they are powering it using dedicated transmitters:
"each floor would have one or two RF (radio frequency) power transmitters to power up all switches inside the house."
It's confusing because earlier they talk about energy harvesting, which implies "free". But then they talk about how you will need to run these transmitters, which certainly isn't free.
That's probably an explanation from Wikipedia or sth
