With Glastonbury coming up next weekend everyone’s getting into the festival mood. Although they can be fantastic fun festivals, come with their own fair share of problems. Some of these are quite trivial, like where to stash the jammie dodgers so your friends don’t find them, but others are much grimmer, like how do you charge your mobile phone.

We’ve all been in situations where our battery has died on us, quite often leaving us in some awful predicament. But imagine how much worse it would be if it meant that you couldn’t film the Kings of Leon performance along with everyone else in the audience? You’d stick out like a sore thumb.

Luckily the best minds in the country (well some people at Orange) having been working hard on the problem. They traditionally release a green festival related project at around the same time as Glastonbury. Last year it was the mobile phone charging welly, this year it’s the mobile phone charging t-shirt.

Called the Sound Charge, this t-shirt uses piezoelectric film to absorb the kinetic energy of sound wave and convert it into a charge which then gets stored in a connected battery. You can then use this battery to charge your phone. With sound levels of around 80dB, fairly quiet by Glastonbury’s standards, it should generate up to 6 watt hrs of power over the weekend. Enough to charge two normal phones or one smart phone, normal being a relative term here obviously.

With the weather still unpredictable and a deluge of thunder and lighting a possible outcome an electrical t-shirt might not survive for long, but still hats off to Orange for innovation. Even if it does look like the kind of garment worn by a crash test dummy.
