AIRE is a mask that converts wind energy (provided by the wearer's breath) into electricity for the recharging of small electronic devices. AIRE can be used in any situation, indoors or outdoors. It can be used while you sleep, walk, run, or read a book, for example. Besides saving energy (and contributing to environmental preservation), it also encourages the practice of physical exercise. Its energy is available twenty-four hours a day, seven days a week.
