Millions of people live in informal settlements worldwide, most of them have adequate lighting. The Liter of Light aims to provide indoor lighting from sunlight at night through the use of Plastic bottles. It is a zero carbon emitting alternative of electricity that uses cheap, durable and readily available materials that produce high quality natural lighting allowing the urban poor to have access to an affordable, environmental friendly alternative to electric light that can be used during the night.

Great movement, congrats!

Very cool - I was actually just reading about LuminAID, which is an inflatable solar light that packs flat. It was initially designed for emergency relief - something that could be shipped and used easily - but would work in numerous situations, like for camping/hiking. Liter of Light obviously seems like an even simpler solution for communities living without electricity.

Such an interesting idea, hope it would come into the implementation part !

Hi Monica, it has already been implemented in some countries.

Hi Kris - this is fantastic - thank you for the post. Are you personally involved in this project? If not, do you have access to the founders? We would appreciate connecting with them and learning more!

Hi, the name of the organisation is Liter of Light. I have already sent them an email through their website regarding about it. Here is their website. http://literoflight.org/index.php.
I hope you guys can connect with them and If there's anything that I can do, don't hesitate to contact me. I believe with my simple contribution, a lot of people can benefit from it. Thank you for the interest!

Bright idea and concept!

I love this idea because it is so simple. Who would have thought a discarded soft drink bottle would make such a great skylight! The video really demonstrates its effectiveness. I looked up the website and noticed that Liter of Lite have made instructional videos so people can make their own, if capable, and also a small solar panel can be attached to provide a night light. Awesome!

One's trash can be other one's treasure as they say. Thanks Lyn!

Its a good evidence based intervention and something that profit companies should support as part of their CSR program. I hope you can convey this idea to them too Kris, be that agent of change :)

Filipino ingenuity at its best. A practical idea that could contribute to lessen the problems of global warming, waste materials, and cost of electricity. Highly achievable project!

A lot of people can benefit from it.

I love this idea! It's so clever and sustainable that will be so useful for everyone not only for people who have no access to electricty but also to everyone who loves to save a bit of cash and the environmentally conscious

Thank you! That is so true!

This is an interesting project that initiated in The Philippines. In 2014, it helped around 28000 homes and 70000 people in Manila. They have integrated an electronic circuit with a lighting emission diode and a photocell to have lighting during night. Although this idea may not reduce the overall energy consumption, it is certainly a good example of sustainable development for the low income population of the world and a smart eco-friendly solution.

Thanks! This idea can really help a lot not only to improve their lives but help save the planet.
