This is literally a brilliant idea =)
The invention is relatively simple. It involves filling up a 1.5L PET bottle with purified water and bleach and installing it onto the roof of a house. The water inside the bottle refracts the sunlight during the daytime and creates the same intensity as a 55 watt light bulb. With the correct installation and materials a solar bottle can last up to 5 years. As the light relies on the sun it cannot be used at night and is only meant to provide light to buildings and homes during daylight hours.
Liter of Light is a global open source movement with the aim to provide an ecologically and economically sustainable source of light to underprivileged households that do not have access to electricity or are unable to afford it.
