The nPower PEG we first tried in prototype form at CES 2009 finally goes on sale tomorrow (May 3, 2010). The PEG is a light-weight, titanium encased portable generator that can recharge a handheld device (phone, media player, camera, GPS etc.) when you are away from the grid, though it is unlike any other mobile power solutions in that you DON'T need any fuel, don't need to turn hand cranks and you don't need the sun. The US$150 PEG is 9 inches long, weighs 9 ounces and harvests kinetic energy as you move about in your daily life. Just put it in your backpack, bumbag, handbag, brief case or glovebox and it will collect and store energy from your movements. The first 1000 units will appropriately be engraved as “First Mover” Editions.
