Sun-Sourced Stove Cuts Pollution in Chinese Himalayas

Replacing wood-burning cookstoves with solar-powered ones could save 500,000 lives in China every year. It's already working in the Himalayas.

Beijing’s blackout smog has been making global headlines, but in China, more than half a million people die each year due to indoor air pollution—often the result of wood-burning cookstoves. Felling trees for cooking has led to rampant deforestation and a way of life where scarcity of fuel, expense of coal and the unreliability of biofuel has left villagers fearful about their future options for cooking food and heating their homes.

For nomadic and agricultural communities in the Himalayan plateau, those difficult health and economic realities have been made easier with an engineering marvel that steals an idea from every kid who’s ever tried to start a fire with a mirror or magnifying glass. The SolSource, one product in a line of solar energy technologies developed by One Earth Designs, is a light-weight, portable cookstove that features five reflector panels that look something akin to a satellite dish with a pie piece-shaped sliver missing.

Supported by a tripod frame, the dish can be turned 360 degrees and titled so the sun hits every panel. Rather than depending upon photovoltaic technology, the SolSource collects and concentrates light at a middling point in the dish, over which users can place a stove pot. The cook stands, safe from potential burns and bright light, in the cut-out, pie-piece shaped area. No electricity is used. As John B. Lindquist, One Earth Designs’ market development manager, explains it, “It’s just like a really powerful magnifying glass.”

In a pilot program last year, the Chinese government bought and distributed 800 SolSource S1 model cookstoves to nomadic villagers in the province of Qinghai, and is evaluating the impact of the stove on people’s lives. Though impact data is still being collected, early responses show dramatic changes in daily life. Women no longer have to spend hours each day collecting wood, coal, and dung to fuel their fires. Some are saving money. Others are spared law-breaking to find fuel. As Lindquist notes “in many cases they are actually having to steal the wood… [because] you can get fined for chopping down wood in many areas.”

Obviously, cooking on SolSource must happen outside, and for approximately 220 days each year, it's sunny enough in the Himalayan region to support the stove’s use. Even in cloud or fog cover, so long as you can see the outline of the sun, the stove works—though it may take a few extra minutes to boil water. To help collect and store energy for sunless days or indoor use, One Earth Designs, the brainchild of co-founders Scot Frank and Catlin Powers, is developing a new line of products to be used in tandem with the SolSource, including a generator to collect and store energy for running heaters or charging cell phones.

The SolSource’s light weight and high-design spin on the old magnifying glass trick make it a draw for campers and barbequers in the developed world as well. (In mid-March, One Earth Designs will be launching a Kickstarter campaign for those interested in using the SolSource recreationally.) But the company’s main interest still rests in helping get their product into the hands of those whose lives quite literally might depend upon it. For that, and at a discounted price by volume, One Earth Designs works in conjunction with governments and NGOs who have the ability to distribute the stoves widely. For a company that designs and builds its products alongside members of the communities it serves, the first goal is finding ways to improve those lives.

Amazon's "The Man in the High Castle" debuted the first episode of its final season last week.

The show is loosely based on an alternative history novel by Philip K. Dick that postulates what would happen if Nazi Germany and the Empire of Japan controlled the United States after being victorious in World War II.

Chick-fil-A is the third-largest fast food chain in America, behind McDonald's and Starbucks, raking in over $10 billion a year.

But for years, the company has faced boycotts for supporting anti-LGBT charities, including the Salvation Army, the Fellowship of Christian Athletes, and the Paul Anderson Youth Home.

The Salvation Army faced criticism after a leader in the organization implied that gay people "deserve to die" and the company also came under fire after refusing to offer same-sex couples health insurance. But the organization swears it's evolving on such issues.

The Fellowship of Christian Athletes explicitly announced it was anti gay marriage in a recent "Statement of Faith."

God instituted marriage between one man and one woman as the foundation of the family and the basic structure of human society. For this reason, we believe that marriage is exclusively the union of one man and one woman.

The Paul Anderson Youth Home teaches boys that homosexuality is wrong and that same-sex marriage is "rage against Jesus Christ and His values."

In 2012, Chick-fil-A's CEO, Dan Cathy, made anti same-sex marriage comments on a radio broadcast:

I think we are inviting God's judgment on our nation when we shake our fist at Him and say, "We know better than you as to what constitutes a marriage". I pray God's mercy on our generation that has such a prideful, arrogant attitude to think that we have the audacity to define what marriage is about.

But the chicken giant has now decided to change it's says its charitable donation strategy because it's bad for business...Not because being homophobic is wrong.

The company recently lost several bids to provide concessions in U.S. airports. A pop-up shop in England was told it would not be renewed after eight days following LGBTQ protests.

Chick-fil-A also has plans to expand to Boston, Massachusetts where its mayor, Thomas Menino, pledged to ban the restaurant from the city.

"There's no question we know that, as we go into new markets, we need to be clear about who we are," Chick-fil-A President and Chief Operating Officer Tim Tassopoulos told Bisnow. "There are lots of articles and newscasts about Chick-fil-A, and we thought we needed to be clear about our message."

Instead, the Chick-fil-A Foundation plans to give $9 million to organizations that support education and fight homelessness. Which is commendable regardless of the company's troubled past.

"If Chick-Fil-A is serious about their pledge to stop holding hands with divisive anti-LGBTQ activists, then further transparency is needed regarding their deep ties to organizations like Focus on the Family, which exist purely to harm LGBTQ people and families," Drew Anderson, GLAAD's director of campaigns and rapid response, said in a statement.

Chick-fil-A's decision to back down from contributing to anti-LGBT charities shows the power that people have to fight back against companies by hitting them where it really hurts — the pocket book.

The question remains: If you previously avoided Chick-fil-A because it supported anti-LGBT organizations, is it now OK to eat there? Especially when Popeye's chicken sandwich is so good people will kill for it?


Oh, irony. You are having quite a day.

The Italian region of Veneto, which includes the city of Venice, is currently experiencing historic flooding. Venice Mayor Luigi Brugnaro has stated that the flooding is a direct result of climate change, with the tide measuring the highest level in 50 years. The city (which is actually a collection of 100 islands in a lagoon—hence its famous canal streets), is no stranger to regular flooding, but is currently on the brink of declaring a state of emergency as waters refuse to recede.

The Southern Poverty Law Center (SPLC) dropped a bombshell on Tuesday, announcing it had over 900 emails that White House aide Stephen Miller sent to former Breitbart writer and editor Katie McHugh.

According to the SPLC, in the emails, Miller aggressively "promoted white nationalist literature, pushed racist immigration stories and obsessed over the loss of Confederate symbols after Dylann Roof's murderous rampage."

The NRA likes to diminish the role that guns play in fatal shootings by saying, "Guns don't kill people, people kill people."

Which is the same logic as, "Hammers don't build roofs, people build roofs." No duh. But it'd be nearly impossible to build a roof without a hammer.

So, shouldn't the people who manufacture guns share some responsibility when they are used for the purpose they're made: killing people? Especially when the manufacturers market the weapon for that exact purpose?
