Solar Bottle Bulbs Provide Lighting Without Electricity [Video]


Bottles filled with water help brighten an underprivileged neighborhood in the Philippines.

In the mini-documentary below, we see how a simple idea that costs next to nothing can make a big difference. The Solar Bottle Bulb was designed by students at MIT and uses only a plastic bottle filled with water to provide natural lighting. The energy-efficient and environmentally friendly idea requires no electricity to power at all.

Currently, the Solar Bottle Bulbs are being installed in Sitios Maligaya in the Philippines to brighten up the community. Over 5,000 tiny houses were constructed on an deserted railroad in this underprivileged neighborhood. Each of the houses are closely spaced and lack natural lighting, making them a hazard and unpleasant to stay in during the day. Electricity is scarce and many of the residents can’t afford to have the light switched on all day.

The documentary was filmed by production group The Jungle Gym for the Isang Litrong Liwanag (A Liter of Light) foundation. The volunteer organization hopes to raise money and support to install more of these eco-friendly bulbs to less-than-fortunate communities in the Philippines.

Watch the short documentary below and be inspired by this simple solution.
