John Donnal '07 and his fellow team members have developed a smart meter that analyzes how much electricity a base uses. Dubbed Wattsworth, the system uses noncontact sensors to measure the electromagnetic field around wires and takes a reading 8000 times per second, compared with the once a minute of traditional sensors. The hub connects to local Wi-Fi networks to communicate with the sensors and mobile devices.  The team won a $3,000 Director's Prize at the Annual Soldier Design Competition in Cambridge, Massachusetts.  More details can be found here.
