So we’ve already shown you how to charge your iPhone over a campfire with a cooking pot, now let’s look at something a little less flammable (maybe). The Orange Sound Charge is a t-shirt that actually doubles as an iPhone charger.

The folks over at TiPb discovered this interesting Orange prototype that combines innovative technology in a wearable accessory. The Sound Charge actually uses ambient noise to give your iPhone battery life. Hit the jump for a video of it in action…

The intriguing device will be put through the paces at this year’s Glastonbury Festival, set to start today. The wearable charging pack will allow festival-goers to to keep their devices powered as they roam the grounds of the 5 day event.

The technology inside this thing is mind blowing. The Sound Charge uses a custom microphone made from Piezoelectric film that “absorbs” invisible sound waves. These sound waves are converted into an electrical charge via interlaced quartz crystals.

I’m anxious to see how this technology progresses. Although I’m not sure if I would want to wear the charging pack, I could see this being implemented in a wide range of products. Solar power is so last year.

What do you think of the Sound Charge? Does Orange have a winner?
