This bridge has a secret. Nearly every GroveAtopian knows exactly where this bridge is and exactly where this picture was taken. So that's not the secret. The bridge's secret is something else.
To find this secret you have to enjoy hunting. But not the kind of hunting that uses guns or other weapons. The only weapons you need for this hunt are patience and your phone.
People who try to discover this bridge's secret will look a bit odd while they are trying to figure it out. They may walk slowly one way, then turn and walk the other. They may cross the street and wander seemingly without reason along the the other side. People who recognize you and wave to you as they go into the feed store will tell you as they come out, "you don't seem to be making much progress on your walk."
"It's not a walk," you tell them as you smile at each other knowing the next time you see them they are going to ask you what you were doing.
Back and forth you walk across the bridge, your had slowly tracing across both the top and bottom railing while you check every nook and cranny. Before now you never realized how many there were on this bridge.
You check under the bridge. Maybe the secret is there. But no! Oh dear! Is someone living under there? Now you are kind of sorry you looked because that is something you didn't want to know. Plus there's more garbage down there than you care to admit.
But still you look. In the tree branches that hang near the railing? Is the the secret there? You really can't believe it's even possible the secret would be in the branches. There are so many of them, it would be downright cruel to hide a secret there.
Looking at your phone, you try to decipher the hints. Some of them mock you by telling you how easy it is to find the secret. How could they be so mean?
Finally, the most tenacious one in your group finds the secret and it is so very small and rather cleverly hidden. It turns out it's pretty much right where the hints said it would be. And many others have found it before us.
How do we know? Because when you find the secret, it tells you so.
COTTAGE GROVE — Here’s one way to look at it: The folks at Aprovecho Research Center want to save the world, one small stove at a time.
And, from the looks of things on Sunday, they may be slowly succeeding — with help from the United Nations.
“In Africa and in Asia, in rural areas, the issue of energy is one of the biggest problems,” said Valentine Ndibalema, one of about 20 people who assembled at a former hog-processing plant on the edge of Cottage Grove this weekend for Aprovecho’s 2011 Winter Stove Workshop.
“We need to find a way to reduce consumption. We are quite interested in seeing how things are done here.”
Ndibalema, a Tanzanian, is a senior environmental coordinator for the U.N. High Commissioner for Refugees in Geneva, Switzerland.
He came to Cottage Grove last week, as did people from Sudan, Sri Lanka, Uganda and Kenya, to spend five days exploring how to build a better stove. The workshop is being put on for staff from the U.N. World Food Programme.
The word “stove,” by the way, means something quite different here from your typical kitchen range. We are talking about the kind of small wood-burning stoves that are in common use by very poor people throughout the world, whether they live in a remote Latin American village or in a crowded refugee camp in Sudan.
Ndibalema works with displaced persons camps, where people cook using whatever fuels they can scrounge and where having a better stove can make a huge difference.
“There is a growing understanding that there is a suite of issues that need to be addressed that have to do with how people cook their food in the developing world,” explained Tom Skeele, the center’s corporate operations officer.
“This relates to air pollution, indoors and out. To safety — people getting burned, especially kids. To lung disease. To deforestation. In refugee and displaced persons camps, women are going outside the camps to find fuel and they are being raped. If we can increase the effectiveness of stoves, then more time can be put into getting a woman or her children an education. Or getting a job.”
The research center focuses on stove design and construction, creating stoves for single-family use (these are about the size of a five-gallon bucket) or for institutional cooking (think 55-gallon oil drum). Aprovecho has even designed a wood-fired autoclave for sterilizing hospital instruments. A small family stove costs about $14.
Outside next to a small garden, Fred Colgan, who is co-director of Aprovecho’s Institutional Stove Project, put his ungloved hand on the bare metal chimney of a big green stove that was boiling a kettle of water in the open air. (It was Colgan’s meeting with Ndibalema in Rome last year, while on his way back from Nigeria, that brought the U.N. staffers here to Oregon.)
“This doesn’t burn you,” he said. “It’s safe to touch anywhere even while the stove is burning.”
That’s because the stove, which is literally built from a 55-gallon drum, is so efficient that the heat goes into boiling water, not making the outside of the stove hot.
“This stove will boil 30 liters of water in 22 minutes using just 1,200 grams of fuel,” Colgan said proudly.
(For the metrically challenged, that means it will bring about 8 gallons of water to a boil using just about 2.5 pounds of firewood.)
The heat is conserved by, for example, designing the stove to wrap around not only the bottom but also the sides of a 60-liter cooking kettle, so that the stove’s intense heat blasts nearly the entire surface of the kettle. As a result, the institutional stoves are up to 90 percent more efficient than stoves generally in use, Colgan said.
While that big stove burned away in the open air, a smaller, family-style Aprovecho stove was boiling its own smaller pot of water atop a concrete pad inside a closed room.
Amit Singh, an officer with the U.N. World Food Programme in Darfur, was standing right next to the stove, just as a cook might. But he was monitoring the air quality in the room with a variety of sensors.
Despite the unvented stove, the air was tangy, but not choking by any means.
Singh is working with Aprovecho to bring 200 of its institutional stoves to Darfur, paid for by the world food program. “We will give them to the schools there,” he said. “We are feeding kids there when they go to school.”
Another participant in the conference is Habib Iddrisu. He grew up in a small village in Ghana, but came to the United States and married a Eugene woman.
Iddrisu wanted to see about bringing Aprovecho stoves back to Ghana.
“People use open fires to cook on,” he said. “I didn’t realize just how bad that was until I came here. I went back there with my wife and family this summer. We realized how much this stove technology could benefit life in Ghana.”
The conference continues through Wednesday.
