DIY Kyoto
DIY Kyoto's "Wattson" is an ingenious device that lets you know when you're using little or too much energy in the home by glowing blue or red accordingly. This slick little gadget even displays how much you will be paying annually in pounds based on the way you are consuming energy at that very moment, driving home the message that environmentally friendly = cost effective. (£125 / Standard version)
