I'd imagine it's scant on details because it's still a theory. The next phase of the competition is funds to build a proof of concept.

For sure, though I question the theory. Directional wireless power I think is feasible, but this sounds like blanketing (1-2 transmitters in a house with no regard for obstacles/direction, per the article). That sounds hugely wasteful, especially given how much more energy power takes vs. signal. I do think a zigbee type solution is the ultimate answer, because even if it goes back to batteries for wall stations, data transmission like that is so much less energy than power that the battery problem becomes null-ish.
