We’re all looking for ways to cut costs these days, and using less energy is a great technique. The AIRE Mask would help you cut down on electricity costs by using your own breath to charge your iPhone. The mask was designed by Joao Paulo Lammoglia as a totally serious concept that won a Red Dot design award in 2011. And besides making you look a little like The Shredder, it’s a pretty good idea.

The device is basically a tiny wind generator that straps onto your face. Your breath turns interior turbines that produce electricity which goes straight to your phone. You can use it at any time – when you’re out exercising, at work, enjoying some quiet time with a good book or sleeping. Although to keep the suspicious looks to a minimum we would have to imagine that wearing the mask while sleeping is the best choice. According to the designer, the mask not only cuts down on energy usage but encourages users to be more active since more breathing = faster charging.
