If you use existing radio stations (preferably AM due to its relatively low and stable frequency) as the source, there will be no additional draw on the grid. You'll be recovering something that is currently being wasted. It won't be enough to be the only source of power, but it helps.

Allie Moore and I have a combined carbon footprint much smaller than that of one average American...
