DIY lamps made from plastic bottles are helping solve the world’s electricity woes | Mashable

A project called ‘Liter of Light’ is hoping to bring light to places that need it most, by using DIY lamps made from plastic bottles. Mashable caught up with the founder of the project to hear how it works and find out who can benefit.

One of the immediate impacts of a natural disaster, like the hurricane that recently wreaked havoc in Haiti, is that it’s often followed by darkness. It takes months for aid, and in this case light, to reach the most remote places.

On a daily basis, more than 1.5 billion people face similar darkness, or at best the dim glow of candlelights or kerosene lamps, whose fumes are poisonous.

Some of these communities are extremely remote and have no access to electricity. Others have access to electricity, but opt out of using it because it’s so expensive.

The problem goes far beyond the lack of light. It extends to long-term issues about security, independence, health and access to education.

An open source project called ‘Liter of Light’ is trying to change this by using plastic bottles to make simple solar-powered lights.

Sarah Kauss launched S’well to rid the world of plastic water bottles | Money Cnn

Plastic water bottles are a divisive issue for many consumers, but not for Sarah Kauss.

The defining moment happened at Kauss’ five-year business school reunion in 2009.

“A professor did a presentation about the global water crisis and the impact on the planet from plastic waste,” said Kauss. “I knew then that my bottle idea had to happen.”

Before then, Kauss would carry other metal water bottles with her but wasn’t happy with their look.

In 2010, Kauss launched her startup S’well, a line of insulated reusable stainless steel bottles that are designed to keep drinks cold for 24 hours and hot for 12 hours.

Since then, the New York-based firm has sold 4 million bottles. The business is profitable and saw revenue surge 400% between 2013 and 2014 — hitting $10 million last year. “We expect revenue to grow exponentially again this year,” she said.

Apparently in many parts of Central America, expensive soda drinks like Coca-Cola are served up in plastic Ziploc bags—instead of glass or plastic bottles—so they’re more affordable. And so the iconic and highly recognizable shape of the Coke bottle isn’t lost, the sugar water maker has created these Coca-Cola bags as a low-cost alternative to its traditional packaging.
