Everyone knows that their game consoles, appliances and HDTVs are energy vampires, and while Energy Star-certified products tell us which gadgets are more green-friendly than others, we still don't know just how much juice they're actually sucking down in a given day. Enter Sassor, a start-up from Japan that's created a system to monitor the electrical consumption of anything plugged into a wall outlet -- from PCs to refrigerators. It tracks power consumption using current sensors clamped onto power cords, which communicate wirelessly via ZigBee with a module (based on an Arduino design) that uploads the info to the cloud.

Through the web portal, users can track energy consumption on a per-device basis in real-time, letting them figure out which gadgets are most responsible for their sky-high utility bill -- and take appropriate steps to correct the problem. Currently, it's aimed solely at businesses, but once Sassor's on its feet, funding-wise, the plan is to also put them in people's homes. The company told us it'll ditch ZigBee in favor of a WiFi solution in such future iterations, and it'll make an SDK and the system APIs available to all so that people can program for the platform and improve it in ways currently not contemplated. Alas, there's neither a timetable nor a price for the consumer version just yet, but you can see some pictures of the hardware's innards below.
