This time it's the AIRE Mask which is a mask that converts wind energy into electricity. And by "wind energy" they mean your breath.
That electricity is just enough in order to charge small electronic devices, and the most popular one would be your iPhone (since we've all experienced the horrible batteries that pretty much all smartphones have today).
The way the AIRE Mask works is that there are small wind turbines in the mask that convert the wind from your breath into electricity which is then transferred to your device via a cable.
The AIRE can be used while you sleep (that sounds really comfortable :S), walk, run, or just lounge around reading a book. João Paulo Lammoglia, who designed the AIRE Mask, says that besides saving energy and contributing to preserving the environment, it also encourages people to exercise.
The AIRE recently won the prestigious RedDot design award but is still just a concept for now. No word yet on if/when it will go into actual production.
I'm not sure people would want to look like Hannibal Lecter when they're walking around, just in order to charge their iPhones, but I certainly have been in situations where I desperately needed more juice for my phone and would have been grateful to have one of these.
They could at least add a voice transformer to it so when you wear it and talk you sound like Darth Vader.
Now that would be cool...
