The innovative mechanic has been using plastic water bottles filled with water and a splash of bleach to light up dark rooms since 2002, and now the idea has spread across the world. It is predicted that by the end of the year, over a million homes will be fitted with the invention and be lit up – without any electricity!
Moser’s method works using refraction of the sunlight. His secret is two capfuls of Bleach added to water in normal plastic bottles, which are commonly thrown away. While some may argue that Bleach is not the most environmentally friendly product, it stops the solution from turning green with algae when exposed to sunlight. From this simple combination, millions of homes may become illuminated.
By drilling a hole in a roof tile and then pushing the filled bottle in from below, the bottle can be kept in place with plastic resin and the new ‘window’ can be made waterproof.
