GravityLight harnesses the power of gravity to provide a realistic alternative to kerosene lamps. The $5 light requires no fuel or batteries, and it takes only 3 seconds to lift the weight which powers GravityLight, creating 30 minutes of light on its descent.
There are currently over 1.5 billion people in the world who have no reliable access to mains electricity. Instead, these people rely on biomass fuels (mostly kerosene) for lighting once the sun goes down. Not only are the fumes dangerous, but they also come with a financial burden. The kerosene can eat away at 10% to 20% of a family’s entire household income.
