    Maybe i left out too much context.

    Im not talking about the research itself, but about how it could be utilized.

    Their idea (having small devices that can be powered by nothing but stray radiowaves) apparently works and is great by itself.

    However its usefullness is limited if you cant somehow connect those devices with the rest of the world. Thats the issue im complaining about.

      There are tons of small devices that don’t have to be connected to be useful. Lots of personal items or small sensors.

        Anything that can be powered by this research, can also be powered by a button sized battery for weeks if not not longer. I thinks its more intended for very off grid stuff but maybe im just too uncreative.
