but if they make wi-fi hotspots more efficient... / billing?

Funny how this comes out at the same time that an industry group has recognized how much power wi-fi hotspots (among other telecom infrastructure) waste, and is trying to reduce that energy waste: ... »

So if there's all this excess energy in the air, should it simply be curtailed, or harnessed? If it's harnessed for wireless battery charging, the next logical question is who pays? Do we need a billing standard? Could you choose to charge your phone just by sitting in a Starbucks, and have the electricity cost billed to your Starbucks card? (Or AT&T bill?)
