\"\"<\/a><\/p>\n

An ingenious solar lighting<\/a> idea is spreading across the slums of the Philippines. This solar light design requires neither a solar panel<\/a> nor a light bulb, however. In fact, all it requires is the sun and a two liter water bottle.<\/p>\n

Light bulbs are only for the very fortunate in the Philippines, as they are not as easily or readily accessible. You can imagine the difference a little bit of light would make in a place where it is hard to find or expensive to purchase a light bulb. Amazingly, this two liter solar light<\/a> requires nothing more than a water bottle filled with water:<\/p>\n

The bottles function as 60-watt lights powered by 100% solar energy. Refraction is an amazing thing, if you drilled a hole in your ceiling light would drop directly through the opening in a straight line casting a shadow on the ground in the shape of the hole. By placing a bottle filled with water into the hole, the light is refracted by the water and emitted at 360 degrees like a light bulb.<\/p><\/blockquote>\n

This is truly a simple, beautiful piece of ingenuity. What makes it even more appealing is that it gives folks an opportunity to use something that would ordinarily go straight to the trash.<\/p>\n

Do you want cheap solar lighting for your home? Then look no further than a bottle of water!<\/p>\n
