What is sustainability – plastic bottle skylights

_69195942_moser_montageGreat article on the BBC wefbsite about a clever guy who has invented a great way of bringing light into the slums of the world without needing to burn oil lamps. “Alfredo Moser’s invention is lighting up the world. In 2002, the Brazilian mechanic had a light-bulb moment and came up with a way of illuminating his house during the day without electricity – using nothing more than plastic bottles filled with water and a tiny bit of bleach” the BBC reported.

If we could manage to get the gravity light distributed at a low enough cost or even free then there would be a much greater independence from energy companies or fuel supplies. I wrote about the gravity light a few months ago.

Don’t think about the energy side of sustainability with this one, think about the increased health of not breathing in the fumes from oil lamps, or the independence from energy companies. Or the cost savings that can be achieved and what could could be used with that money – education for the children, healthcare for the sick or food.

If you think about the definition of innovation that I love the most – innovation is cutting out the unnecessary – then this innovation is awesome. It removes the unnecessary need of using artificial light during the day,

Thanks to Cundallites Joanne Sim and Dave Clark for sending this one through. Love it.
