Check out this video – some village ingenuity goes a long way when you’re faced with power outages! Alfredo Moser, the inventor, lives in Brazil and dealt with trying to work in the blackouts in 2002. He took a 2-liter bottle, two capfuls of bleach, and a 35mm film canister and made a light source that puts out light metered at around the intensity of a 50W light bulb! Alfredo’s invention has been allowing his neighbors to light their homes during the day with the sun and no electricity.
Thanks, WiseBread!
