Light liters: free lighting for the poor
A plastic bottle, water and a couple of spoonsbleach - this simple idea has become a successful solution to the problem of lighting slums and shacks in the Philippines. The simple technology allows you to light up always dark rooms without normal windows, but only when the sun is shining outside. Light is available to poor residents absolutely free of charge. This idea can be perfectly implemented anywhere in the world.
In this way, it is possible to illuminate the villages of Ukrainesheds, outbuildings, toilets outside and other buildings "without windows and doors". Fortunately, on average there are about 270 sunny days in Ukraine. And in the slums of Manila, Philippines, the innovative project became a real gift and illuminated the gloomy and dreary hovels of the local population.
The technology is very simple and absolutely accessibleeach. Pour water into a regular plastic bottle and dissolve two or three spoons of bleach (chlorinated lime). Insert the filled bottle into a cut hole in the roof, secure and seal. This way, the homemade lamp sticks out halfway above the roof, and the lower part works as a light bulb in the room. The water refracts and scatters the sun's rays throughout the room, and the bleach prevents the water from stagnating and blooming.The initiator of the project is ecologist and entrepreneur IllacDiaz. The original idea belongs to students of the Massachusetts Institute of Technology. “The idea is that light, passing through a bottle of water, enters the room as if through a window in the roof,” explains Illac. “In the case of a simple hole or window, the light will go in a straight line. And water refracts the rays and directs them in all directions. The result is 55-60 watts of sunlight during sunny days.” The project is known as “Liter of Light” and is aimed at providing poor areas around the world with cheap energy.
