£25 fridge gadget that could slash greenhouse emissions David Adam, environment correspondent Saturday March 17, 2007 The Guardian It is made of wax, is barely three inches across and comes in any colour you like, as long as it's black. And it could save more greenhouse gas emissions than taxes on gas guzzling cars, low energy light bulbs and wind turbines on houses combined. It is the e-cube, and it is coming soon to a fridge near you. Invented by British engineers, the £25 gadget significantly reduces the amount of energy used by fridges and freezers, which are estimated to consume about a fifth of all domestic electricity in the UK. If one was fitted to each of the 87 million refrigeration units in Britain, carbon dioxide emissions would fall by more than 2 million tonnes a year. The patented cube mimics food and is designed to fit around a fridge's temperature sensor, which usually measures the temperature of the circulating air. <more>
