Solar powered light bulb lights up homes of poor communities

SHARE

It’s a sad reality that there’s still a lot of poor communities around our country who are literally living in the dark. Places like Sitio Maligaya Dos in San Pedro, Laguna. Informal settlers have built their houses so close together that almost no sunlight reach into their homes. And because these are extremely poor communities, they can’t afford to electrify their homes – which subsequently leaves them struggling in the dark, even if the sun is shining outside. Enter the solar light bulb, an ingenious bit of tech created by students from MIT. Constructed out of discarded PET bottles, bleach and distilled water, these bulbs give poor communities a way to see in the dark. The constructed bulb delivers light that’s equivalent to a 55-watt electric lamp and can last up to 5 years, and only cost Php 100 to 200 to make. Armed with the know-how of the solar light bulb, people like Mang Demi Solar helps communities like the one in Sitio Maligaya to see the light by installing them in the homes of the poor.
