Greener Gadgets Design Competition 2009

Core77 has launched the Greener Gadgets Design Competition 2009 in collaboration with CEA to generate outstanding design innovations for greener electronics. The Greener Gadgets Conference’s event was introduced in January 2008 and was a tremendous success, drawing over 1000 entries from all around the world. The Winner who took away $3000 was Tweet-a-Watt, a twittering power meter. The eco gadget is a Kill-a-Watt with a capacitor and transmitter added that would Tweet your current power usage using a nearby computer or wireless Arduino mini PC. A large capacitor that charges, transmits, and then discharges over time is then used to power the transmitter, after which an XBee module come into action to transmit the information read by the Kill-a-Watt, giving you an up-to-the-minute reading of your energy usage.
