I love to hear of someone making a big difference with a simple idea, and today’s post tells such a story.
In 2002, Alfredo Moser, a Brazilian mechanic, wanted a way to light his workshop during a power outage. The solution he devised was to lower a plastic soda bottle filled with water and a bit of bleach down through a small hole he cut in the roof. Sunshine hitting the part of the bottle above the roof refracts in the bottle inside the house, and provides as much light as a 50 or 60 watt bulb.
The benefit that comes from Alfredo Moser’s innovation is out of all proportion with its cost to manufacture. And the Moser light is the core of projects in many different countries that literally light up the lives of hundreds of thousands of people.
In the Philippines, Illac Dias is using the Moser light as the centerpiece of a project called Liter of Light. Here’s an example of the need and how people are using the technology in one community:
And here’s an adaptation that addresses after-dark needs:

If you’re inspired by the idea and can’t wait to build your own, Illac Dias has a how-to video to help you out.
“Light it up” is also the closing lyric from a favorite music video I’ve featured in the past. Because great ideas deserve a happy dance, and because I just love it, I’m bringing the video around again, in case you haven’t seen it before. If you have, you’ll most likely want to see it again.* Switch now to the biggest screen or format you have access to, and enjoy!
