A light-bulb idea that makes a real difference, free-of-charge...

Just when manufacturers were focused on LED light competition, and power suppliers were adjusting for lower consumption, Alfredo Moser, a Brazilian mechanic had a light-bulb moment and came up with a way of illuminating his house during the day without electricity - using nothing more than plastic bottles filled with water and a tiny bit of bleach to refract 40-60 watts of light into the room below, free….

First he makes a hole in a roof tile with a drill. Then, from the bottom upwards, he pushes a water-filled bottle into the newly-made hole. "You fix the bottle in with polyester resin. Even when it rains, the roof never leaks - not one drop."

In the Philippines, where a quarter of the population lives below the poverty line, and electricity is unusually expensive, the idea has really taken off, with Moser lamps now fitted in 140,000 homes. The idea has also caught on in about 15 other countries, from India and Bangladesh, to Tanzania, Argentina and Fiji.

Another case of consumers, strapped for cash, 'making  do' with cheaper alternatives...
