[RFI] turnabout is fair play??

[Dave Bernstein]

The power being distributed is DC, so the 60hz DXers can rest easy.
Disturbances near the graves of both Edison and Tesla have been noted...

Which brings to mind an entirely different solution to BPL: wireless
transmission of power. If we could get that working, we could eliminate all
those unsightly power lines -- and with them BPL.

David,

This is Power Over Ethernet (PoE) and the IEEE has already formalized 
the specification as IEEE 802.3af. There are many community wireless 
and hot spot providers who use this to place their APs near outdoor 
antennas so as to minimize loss. You can also find lots of 802.11[abc] 
devices that have PoE support built in, and custom adaptors for 
retrofitting devices that do not have this support.

The IEEE specification can be found at 
http://www.ieee802.org/3/af/index.html .

Although I did find your ironic comment about power over broadband 
lines pretty funny, I thought others might find the official specs 
interesting.
