Our friends over at PlanetGreen.com have gotten their hands on some super cool Votaic Solar back packs.

PlanetGreen is giving away two solar backpacks per week. Use the bag to charge your laptop, iPod or virtually any other handheld electronic device. They come with batteries to collect solar energy collected in three solar panels and are made with fabric from recycled soda bottles.

The best part? You can enter each week for a new chance to win!
