Mr Teslas vision seems to have surfaced again, in a smaller form maybe. See
Any thoughts on this? Based on work I've done on underground communications using near field equipment, it doesn't look totally kosher to me. Unlike a microwave path, near fields can't be focussed to any degree AFAIAA, If there's 60 watts available at 2 metres, then there could be significant RF energy available around the source in many directions. Lower frequency than mobile phones, but tens of watts rather than milliwatts involved. And if the geometry is over a couple of metres, there would be a significant amount of RF radiation as well, the regulatory people may not be too impressed with one in every second home.
