This invention uses plastic bottle instead of glass bulb, and can help people solve lighting problem in day.

This simple invention of “solar energy bulb bottle” is very easy to make. You just need to put purified water into lucid bottle, then add a little bleacher to prevent breed of germ. Then you can install the bottle to roof, half is outside the roof and half is inside the roof. Sunshine will refract into house through purified water and light every corner of house. It is a good way to save electric energy with low cost and high effect.

According to express of inventors, they plan to utilize this solar energy bulb bottle to solve the lighting problem of 1 million poor people’s slum-dwellers. According to comprehend, every solar energy bulb plastic can use for 5 years, and the light released by it is similar to a bulb of 55 watt. Compared with normal household bulb, a solar energy bulb bottle can reduce 17 kilogram discharge of carbon dioxide, not only for saving electric energy.

It is reported that many residents of India, Columbia and Pacific island country are beginning to use this solar energy bulb bottle which is energy saving, electric saving and environment protecting.

When we are enjoying the convenience of electric lights, bathing in sunshine, do not forget, a ray of light coming through the tin roof, the light is not just light limited space, but also light unlimited dreams.
