The Brazilian Light Bulb Hack – Lots of Light, No Electricity?

YouTube player

The rising cost of living has left many people looking for ways to cut expenses, especially when it comes to energy consumption. Men everywhere are having to leave their torrent boxes on less to save money for more important things, such as alcohol; perhaps these sacrifices are unnecessary, though.  This video shows a very simple creation that generates as much light as a 50 watt light-bulb, and uses absolutely no electricity. How did Brazilian engineer Alfredo Moser do it? By drilling holes in his roof and installing clear plastic 2 liter bottles filled with a mixture of bleach and water.

The science behind this is somewhat of a mystery to me. Some people suggest that the shape of the bottle is responsible for the fixtures ability to generate so much light, while others say that the bleach acts in such a fashion as to diffuse the incoming light and project it out much like a standard light-bulb would. Whatever the mechanics behind this feat, I can see this being an excellent alternative to traditional light-bulbs – at least during the day.

If any of you could shed some light on the science behind this technology, I would love to hear from you.

  1. According to me the government of the Brazil has to make strong security on that things . So any other person not suffer for this types of the situation .

  2. The bleach does not participate in the lighting itself. It is there simply to kill germs and mould that would otherwise grow in the bottle and reduce the clarity of the water.

  3. Alfredo Moser is a genius! A standard of living raiser for the third world as well as a first world toy. There is a group called My Shelter in the Philippines who build homes with this type of lighting.
