Charging Mobile Devices With Your Own Physical Movements

January 5, 2011

The nPower PEG, developed by Tremont Electric, harvests electrical energy that would otherwise be lost.

The device generates electricity and refills its battery from your daily movements.

Plug your mobile electronic devices into the PEG (Personal Energy Generator) and it will recharge.

“It’s for any outdoors enthusiast who is deep in the woods and doesn’t have access to a power outlet or for a commuter who constantly needs backup battery power,” Jessica Davis, Director of PR and Sustainability for Tremont Electric, is quoted as saying by the AFP news agency.

PEG batons measure nine inches (23 centimeters) and weigh 11 ounces (312 grams). Electricity is generated when floating magnets slide through coils, according to Davis. The batons can be put in a backpack, brief case, or runner’s pouch where they synch to up-and-down motion to generate power.

“It tunes to optimize the amount of power being produced,” Davis said.

PEG works with more than 3,000 handheld devices that are USB 2.0 compatible.

The Ohio-based company began selling the 160-dollar “kinetic” chargers in September and has been scrambling to catch up to demand.
Inventor and entrepreneur, Aaron LeMieux (a.k.a. “Doppler”), came up with the idea for the nPower PEG while backpacking 1,500 miles on the Appalachian Trail. As a mechanical and biomedical engineer, Aaron recognized the kinetic energy that was being wasted as his backpack rubbed against his shoulders and hips with every step. He also had to stop at towns along the way to buy disposable batteries to keep his devices running.  It was during this trip in 1996 when Aaron began thinking of ways to capture this energy and create usable electricity to charge hand-held electronic devices.
