With so many young people these days listening to their iPods at very loud levels, it won’t come as a surprise that many years from now, these same once-young people will have a diminished sense of hearing, which is why the market for hearing aids has plenty of room to grow. How about being more eco-friendly in the future as well by starting today with the Solar Ear? This is the first solar-powered hearing aid rechargeable charger in the world, featuring a couple of rechargeable Ni-Mh AA batteries that take up to 8 hours of direct sunlight to charge. When fully juiced up, just place the hearing aid batteries inside and you’re good to go. The unit’s batteries are touted to have a lifespan of 2 to 3 years, which is the equivalent of 300 charges.
