Alfredo Moser (Uberaba) is a Brazilian mechanic and inventor.


Born in Uberaba, Minas Gerais in Brazil. He married Carmelinda in 1978. He invented what is known as the Moser lamp.[1]

Moser lamp[edit]

Moser invented a lamp in 2002, using a plastic bottle filled with water fitted through a roof, which works by refraction of sunlight. It produces similar brightness to a 40- to 60-watt incandescent bulb during the hours of daylight, and uses no electricity or power other than natural light.[2] It is easily fitted through a simple roof.[3]

It was created as a response to constant electrical power cuts in Brazil. It lights, at no cost, many homes in many countries, including Philippines, India, Bangladesh, Tanzania, Argentina and Fiji.[4] The movement became known as the Liter of Light.

Moser says "It's a divine light. God gave the sun to everyone, and light is for everyone. Whoever wants it saves money. You can't get an electric shock from it, and it doesn't cost a penny."[5]
