A Liter of Light: how an invention can help the world change.

Access to modern clean energy should be granted to every person. Having a 24 hours supply of electricity in your home gives you more safety and higher quality of life. Additionally, it gives you more opportunities: would it studying or reading at night be possible, for example? This is the reason why access to non-stop energy is a discriminator in our world, where almost 20% of the global population lack of access to electricity. Practically, 1.3 billion people live in the darkness.

We have a energy poverty problem, period!

However, today we want to tell you a story about how a common item easily is helping worldwide to fight this tremendous energy scarcity.  A Brazilian inventor, Alfredo Moser, an enlightened person, developed a technology that uses plastic bottles to provide light. And the most beautiful thing is that is as simple as ABC.

Just fill up a plastic bottle with water, add some bleach, seal it and install it in hole in the roof. What you have is a clean and cheap light bulb. You may do not believe us, look at the video:

The light bottle can provide as much energy as a 40-60 watt light bulb and it can last up to 5 years. Moreover, it reuses plastic bottles that otherwise will go wasted.

A plastic bulb is good for two reason consequently: Affordable electicity for people and recycling of plastic material!


After Mr. Moser invention, a grassroots enterprise called My Shelter started to bring light to the darkest place in the world. Since 2011, the movement has expanded and has helped hundred thousand of people. By the end of 2015 over 200,000 bottle bulbs were installed in communities around the world.

The goal of a Liter of Light is both ambitious and inspiring, as they want to light up more than 1 million homes in the following years.

Take some times and have a look on their web site www.aliteroflight.org. There is also an easy-following tutorial to build your own light box. I am already building mine, so what are you waiting for?

Spread the voice and lets steamgreen and light up the world.
