An anonymous reader writes "Researchers at UC Berkeley have released their open-source system for monitoring AC power through the Green Soda project.
The AC meters, called ACme, plug into wall outlets and power strips, and form an ad-hoc IPv6 subnet accessible from the Internet.
There are over 50 different switches, desktops, and kitchen appliances (and an Xbox!) being monitored by the system.
The data is available in real-time on the project web page.
Their goal is to significantly reduce the 500kW draw of the computer science department."
