Nearly a century ago, German engineer Anton Flettner launched a ship into the ocean. "Without sails or steam, like a ghost ship, it moved mysteriously through the water with no apparent means of propulsion," according to a 1925 article that appeared in Popular Science Monthly. The ship cruised in silence, without spewing anything into the air. Curiously, two odd-looking, giant spinning cylinders rose from her deck as "the ship plowed its way through the rough waters of the Baltic, at nearly twice its former speed," the article said.
Sending dozens of emails a day, making a quick call on WhatsApp, uploading some photos to the cloud, watching a short viral clip on YouTube: It's all part of the digital daily life around the world. For the individual, it may be "just one photo" or "just a few minutes of video," but, taken together, our collective internet traffic contributes enormously to climate change.

Everyone's talking about self-driving, autonomous vehicles these days. Late last year General Motors announced that it will shut down production of several conventional car lines, partly to pour resources into its self-driving car unit, and GM is just one of many companies ramping up such efforts, alongside Google, Tesla, Uber and a slew of others. But what kind of transportation future will this autonomous vehicle revolution bring? And who will it benefit? In a country with an increasing divide between rich and poor, what will this whiz-bang technology mean for marginalized groups such as the poor, people of color, the elderly and those with disabilities?
Air pollution within the home causes 3.8 million deaths a year, according to the World Health Organization. A recent University of Colorado in Boulder study reported by The Guardian found that cooking a full Thanksgiving meal could raise levels of particulate matter 2.5 in the house higher than the levels averaged in New Delhi, the world's sixth most polluted city.
But soon, you will be able to shop for a solution in the same place you buy your budget roasting pans. IKEA is working on a specially-designed, air-purifying curtain called the GUNRID.

As an environmental lawyer for over 25 years now, I have become intimately familiar with the workings of the U.S. Environmental Protection Agency (EPA) and the Department of the Interior. I didn't have occasion to watch what was happening across town at the Federal Communications Commission (FCC). Now I do. Here are 10 reasons why you might want to also.
The latest renewable energy breakthrough took place over a lunch.
Sudeep Joshi, a postdoctoral fellow at Stevens Institute of Technology, told BBC News that he and some colleagues were discussing the problem of cyanobacteria. These are organisms that can convert sunlight into electric current. The problem? They don't live long enough on artificial lab equipment for researchers to be able to take much advantage of that fact.
For Bill Gates, toilets are serious business. The billionaire philanthropist kicked off the Reinvented Toilet Expo in China and unveiled a new toilet that does not require water or sewers, and uses chemicals to turn human waste into fertilizer, Reuters reported.
"We are all here for one reason: because more than half the world's population doesn't have the safe sanitation they need to lead healthy and productive lives," Gates said in a speech on Tuesday in Beijing.
The program is a partnership with Aclima, a San Francisco company that maps air quality on a block-by-block scale.
