A Hercules ePlug is shown at a home in Marborough, Mass., Tuesday, Sept. 1, 2009. The ePlug uses a standard network port to connect to a computer, then uses the electric circuit of a home to receive Internet signals from a companion ePlug in an electric outlet and cabled to the Internet in another room.

Pretty old news. I did a presentation about this 5 years back.

Was it marketed then? I think this technology was in news long ago as a source of high speed internet but I didn't see any product. Maybe I didn't pay much attention. Sorry if this is old or obsolete.

It was great when it came out, but never bought it though. I think there is Chinese variation available in the market.
