Everything is going solar these days, even hearing aids. With low-cost and energy efficiency in mind, the Brazilian-based company Solar Ear has created eco-friendly hearing aids powered by energy from the sun.
Solar Ear's affordable hearing devices use solar-powered batteries, which make them a greener alternative to traditional aids as they cut back on fuel-based power and battery waste. The batteries used in the Solar Ear device also have longer life spans than normal hearing aid batteriesâ€”two to three years versus one week.
