USB Battery for the nerdy environmentalist

Just came across this site through a Facebook contact. Look as though you can buy them in Canada and the US already, so I may be behind the times... Little device that fits a AA battery size device, is rechargeable, and flips to expose a USB connector to charge anywhere you've got a computer. If you ask me, this is an amazing confluence of design, engineering and heart. Why aren't there more devices that reduce waste, add convenience and look cool? I recommend checking it out. Click HERE
