Have you heard of Alfredo Moser? He is Brazilian, a mechanic, born in the Minas Gerais city of Uberaba and responsible for illuminating the lives of more than a million people who lived in different parts of the world without access to electricity. electricity.

It is that, without much pretension, Moser developed a way of producing light with PETs. The idea came about in 2002, during a period of constant blackouts in Brazil. To avoid being left without lighting at home, the miner invented a way to have light from plastic bottles and, because it was so good, the idea spread around the world – no royalties, nothing!

Of course! PET lamp The lamp created by Moser is very easy to make. All you need is a 2-liter plastic bottle, water and a little bit of chlorine. According to the Minas Gerais native, you need to fill the container with the chlorine, add two capfuls of chlorine (to prevent algae from growing) and close the bottle. Oh! And here's a tip: covering the lid with black tape helps the homemade lamp work better, says Moser.

Then, just drill a hole in the roof, fit the bottle with the mouth pointing towards the sky and secure it with resin glue to prevent leaks. That's it! The PET lamp is capable of producing 40 to 60 watts through the refraction of sunlight, and you'll save money on your electricity bill. How about trying it at home?

The invention has already benefited many people in Brazil and abroad. People from countries such as India, Bangladesh and Fiji, who live in poor regions without access to electricity, have already adopted Moser's method. Even the NGO MyShelter, which builds houses with recycled materials for people in extreme poverty, has embraced the Brazilian mechanic's technique. Hello, Moser! Literally, lighting up people’s lives…
