Amazing invention uses, otherwise wasted, plastic bottles to cleverly harvest the sun light to illuminate WINDOWLESS ROOMS in poor countries.

Amy Smith was at our offices in Haiti this past spring with her student Kofi Taha. They built a quick mockup of this invention on our roof with a cardboard box, lamina, tape, a water bottle and silicone caulk.

Aside: I have to say, one of the biggest lessons I’ve learned from Amy Smith is that when you have an idea, get out there an prototype-test, prototype-test, prototype-test. A lot of new engineers and designers these days spend way too much time using CAD and not making their ideas real in the material world.
