How does the Moser lamp work?

This water filled bottle invention, known also as the ‘Moser Lamp’, works by refracting (or bending) light through different materials. In this case, light moving from air through water and plastic. So when light hits the water filled bottle, it refracts and spreads light throughout the room beneath.

What is the Moser light?

Moser lamp 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.

How can a bottle of water light up a room?

A project called Liter of Light has a solution. Its creators discovered that plastic bottles filled with a mixture of water and bleach “refract the light from outdoors into the house, lighting up much like a light bulb.” When placed on the roof of a house the bottle becomes an adequate and inexpensive source of light.

How does the Liter of Light Work?

Liter of Light (Day) is an affordable DIY lighting system that allows the sun’s rays into homes, schools and public centres for US$2 per unit. Sunlight refracts through the bottle to light the space below with 55-watt of brightness.

How do solar bottle lights work?

So how does it work? Simple refraction of sunlight, explains Moser, as he fills an empty two-litre plastic bottle. “Add two capfuls of bleach to protect the water so it doesn’t turn green [with algae]. Then, from the bottom upwards, he pushes the bottle into the newly-made hole.

How do you make a Moser light?

In 2002, Brazilian engineer Alfredo Moser invented a simple way to bring the sun’s light indoors: fill a clear plastic 2-liter bottle with water and two capfuls of bleach, then make a hole in the roof and secure it with a waterproof sealant. The result: 40 to 60 watts of free, natural light.

How did liter of light start?

Liter of Light was started up in the Dominican Republic by the German volunteer Nicolai Rapp in 2015 who then distributed the project with other German and local volunteers in over 7 provinces. They achieved the installation of bottle and solar nightlights in more than 1000 houses with global fundraising.

Who started liter of light?

the My Shelter Foundation
Inspired by green innovations from across the globe, the My Shelter Foundation launched A Liter of Light in April 2011, bringing eco-friendly solar bottle bulbs to impoverished communities worldwide. Their goal is to light one million homes by 2015.

Do solar bottle lights work at night?

‘The Liter of Light is actually a day-and-night solution,’ Diaz says. The solar bottle bulb provides up to 55 watts of light during the day, while the solar power upgrade—comprised of one-watt or three-watt LEDs—operates in the evening.

How does a Moser lamp work?

In the case of the “Moser lamp”, the Sun ‘s light is bent by the water in the bottle, and spreads around the room. While Alfredo Moser is credited with pioneering the use of plastic bottle skylights in Brazil, charities and non-government organisations like A Liter of Light are spreading the light throughout the World.

Where did Alfredo Moser install the bottle lamps?

Alfredo Moser went on to install the bottle lamps in neighbour’s houses and the local supermarket, in Uberaba (Southern Brazil), the city where he lives.

How did Alfredo Moser light up the world?

Alfredo Moser’s invention is lighting up the world. In 2002, the Brazilian mechanic had a light-bulb moment and came up with a way of illuminating his house during the day without electricity – using nothing more than plastic bottles filled with water and a tiny bit of bleach. In the last two years his innovation has spread throughout the world.
