Question is whether this could harvest enough energy to store it in a small battery to continuously provide power. But really sounds frightening if you change the setup of a few appliances and then suddenly half of your autonomously powered devices don't get enough power anymore because the noise is not high enough anymore.

On a more serious note, I'm sure that if you needed a reliable network, you would use purpose built emitters to power everything.

could be very useful in-doors where solar is not possible and wiring is not practical. A lot of sensors do not have to be on all the time - occasional reading is more than enough.

It's quite amusing what this comment attracts so many up and downvotes, yet no one comments why.
