Continuing the theme of self-improvement, here's another chance to do your bit for the planet.

Our Newsdesk alerted you to this cool little gizmo back in July, but having only recently hit the shops we thought we'd remind you all about it.

It's called Wattson and it tells you how much electricity you're burning using all the lovely gadgets you keep buying. And don't worry - it doesn't do it in amps, volts, watts, yargs, nano-whotsits or anything else too technical. It tells you in cold hard cash.

We love this product and if every house had one, those polar bears and penguins wouldn't look quite so anxious now would they?
