In 2002, Brazilian engineer Alfredo Moser invented a simple way to bring the sun’s light indoors: fill a clear plastic 2 liter bottle with water and two capfuls of bleach, then make a hole in the roof and secure it with a waterproof sealant.
The result: 40 to 60 watts of free, natural light.
How does it work? The bleach keeps the water from turning green, and the water refracts sunlight. To see this innovative but simple invention in action, watch the the ecoideasnet video above (with captions on). Chilean Miguel Marchand helps to install the bottle lights, or Moser Lamps, in the home of a family that lives in the Andes.
Around 1.6 billion people — 25% of the Earth’s population — live without electricity, but with this simple idea, they can enjoy sustainable light in their home for free. Moser Lamps are becoming popular solutions in the Philippines, India, Bangladesh, Tanzania, Argentina, Fiji, and other countries, and give an incredibly useful second life to plastic bottles.

What is a gyre? And how does this natural phenomenon demonstrate the impact of our plastic trash? Anna Cummins and Marcus Eriksen of 5 Gyres Institute explain how we can understand the international issue while acting locally:
"It is impractical to try and scoop out trash out of the ocean. What we can do is wait for it to wash ashore. So to clean a gyre, clean your beach, clean your watershed, clean your street. As close as you can get to the source, is a better way we can solve the problem of plastics in the ocean"
This Nike Better World promo video from 2012 shares the manufacturing process of how plastic bottles can turn into “the most advanced football jerseys on the planet.” (And by the way, that’s soccer/football, not American football.)
There are some excellent vids about plastics and sports in the archives.
From National Geographic’s I Didn’t Know That, this flexible, concrete-laced canvas can be put up by two people and ready to use as shelter within 24 hours. It’s essentially a building in a bag. With water to activate the concrete and air to inflate it into shape, the concrete hardens into a solid structure that resists fire and water. It can even become a sterile, hospital-like environment, an essential need in humanitarian crisis situations.
