TECH: Scared of Wi-Fi but want internet around the house?

I'm a little paranoid about Wi-Fi. In fact, not just Wi-Fi. I'm also concerned that mobile telephones/Wi-fi combined will be the real 'boiling frog'* event of our generation (as opposed to global warming).
I therefore wanted to cut down on the amount of radio waves buzzing about my home but struggled against the convenience of being able to use a laptop in any room.
Thankfully there is a solution: Powerline plugs.

Powerline adapters have been around for a few years but are now really affordable. I picked mine up for £40 for two. They are plugs with a network plug built in. They use the electrical circuit of your home to carry network traffic. Pretty good, eh?

Here's the simplest illustration. Attach a network cable from your router to Powerline plug 1. Plug this plug into the wall. Now, plug Powerline plug2 in somewhere else in the house, and attach a network cable from it, to the device you want an internet connection on. That simple. No drivers. No configuration in Windows, Mac or Linux. Just plug them in any they work. Best of it is, when you want the connection in another room, just move plug2 to that room and plug in there. Oh, any no nasty Wi-Fi signals (apart from the 20 other people living nearby) requiring the use of a foil hat...

*The boiling frog story states that a frog can be boiled alive if the water is heated slowly enough ? it is said that if a frog is placed in boiling water, it will jump out, but if it is placed in cold water that is slowly heated, it will never jump out.

The story is generally told in a figurative context, with the upshot being that people should make themselves aware of gradual change lest they suffer a catastrophic loss. [from Wikipedia]
