REPLAN IT brings to life the science of “appropriate technology” – using engineering techniques and physical structures, machinery and manpower, to meet the specific needs of diverse communities. The technology uses only the material at hand or readily available. It can be built at a low cost and operated and maintained by the local community with limited outside assistance. Jock will use his expertise to change lives in the developing world and right where you live. In each series, we'll show you “ground zero” of the appropriate technology movement – the classrooms of some of the most prestigious universities in America – to watch the incredible work of tomorrow's greatest minds. And for the viewer at home, we'll show inspiring projects that can be applied in the kitchens, basements and back yards of Main Street America.

"A Liter of Light"

January 30, 2013
This episode of REPLAN IT introduces the bottle light: a low-cost solution for darkness around the world. Developed at MIT, this invention is constructed with only a soda bottle, water and bleach. Bringing light into the darkest of places, the bottle light requires only sunlight and as a result, no electricity is required. Watch as this simple invention is taking the world by storm.
