Bottle Light : Alfredo Moser's invention is lighting up the world. In 2002, the Brazilian mechanic had a light-bulb moment and came up with using the Sun's power without electricity - using nothing more than plastic bottles filled with water and a tiny bit of bleach.

Simple Idea : So how does it work? Simple refraction of sunlight, explains Moser, as he fills an empty two-litre plastic bottle. "Add two capfuls of bleach to protect the water so it doesn't turn green [with algae]. The cleaner the bottle, the better," he adds. Wrapping his face in a cloth he makes a hole in a roof tile with a drill. Then, from the bottom upwards, he pushes the 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. The inventor is proud to be poor... in developing nations where electricity may be intermittent, this is a sustainable alternative, though it only works in the day!.
