(PhysOrg.com) -- By applying the NetFlix model of movie swapping to batteries, a team of researchers and students from MIT and Harvard is hoping to provide electricity to thousands of homes in Tanzania. Their start-up company, called EGG-energy, offers a battery subscription service where individuals can return a used battery and pick up a fully charged one when needed, about every three days. The strategy not only provides a safe, clean source of energy for basic needs such as lighting, radios, and cell phone charging, but it should also save customers up to 30% on annual energy costs.
