Cities everywhere have bike share programs, but the people who use them often do not use helmets. The EcoHelmet, designed by Isis Shiffer, is a recyclable, inexpensive solution designed to fill that need. It is made with “waterproofed [biodegradable coating lasts three hours] recycled paper in a radial honeycomb pattern” and one size generally fits all. It has been crash tested at Imperial College, London and passed European standards (according to www.jamesdysonaward.org). When folded, it may be dispensed to users via a vending machine for as little as $5. The EcoHelmet is still in development, but you may see these soon at a bike share rack near you!
