3M Ethernet-powered TV ditches conventional plug

The company claims that its polarizers can help reduce the power requirement of LCD screens and, as such, we've now reached a point in time where the traditional power socket is no longer needed to drive our screens around the home. It's not as simple as just plugging something into an Ethernet port and expecting it to draw power. It has to be a powered Ethernet port, which requires PoE or Power over Ethernet - a defined standard, but not a commonly found feature on home routers. But, the company also claims that Ethernet power ports are more affordable to install, and you don't need an electrician around to house to do it for you, so maybe it'll catch on. Plus, you'd have a wired network reaching every room of your house, and in a world where so many competing signals are playing havoc with many homes' wireless networks, that's of enormous benefit. The big real benefit we can see from this is that if this idea takes off, you'll only need a single cable for the TV of the future for both power and internet access, which might very well be the only two things TVs will be needing in due time.
