Keeping cool

first_img“We could develop a whole new workshop on building for a war zone,” said UGA Cooperative Extension engineer Michael Czarick. After coming to the United States solo in 2006 to learn about keeping chickens warm in the winter, Kaye brought seven other growers and two Israeli extension workers back for the hot weather workshop.He wasn’t the only international attendee. The workshop, which gives Georgians priority, pulled participants from 15 states and nine countries. Czarick said this mix adds value to the workshop far beyond the lecture and learn structure. “What’s nice about the diverse crowd is that there’s a lot of knowledge transferred,” he said.Czarick, UGA poultry scientist Brian Fairchild and UGA Extension engineer John Worley have been training poultry producers, equipment dealers, service people, college students and UGA Extension agents on the ins and outs of keeping poultry cool for 11 years. “We started the first one and thought we would do it one time,” Czarick said. The initial training was limited to broiler producers in Georgia. But the companies represented in the first workshop wanted to offer it to more of their employees. Then international groups got word.“Though it’s a Georgia workshop, it’s the only thing of its kind in the world,” he said. This year, the workshop covered everything from the importance of air speed in tunnel-ventilated houses to exhaust fan selection.Faircloth’s session on managing bird migration in tunnel houses went over the importance of putting up fences in a chicken house. He explained that chickens like to move toward the wind. Keeping chickens spread evenly throughout a house to prevent heat buildup is like “herding cats, although chickens are a little easier,” he said.Christine Maziero, a veterinarian from Concordia, Brazil, spent years using information from UGA’s College of Agricultural and Environmental Sciences on how to incorporate minimum ventilation in their poultry houses.The workshop is “helping us to understand better all of the systems and improving our barn construction,” she said. “After being in touch with these people who have much knowledge, it’s a pleasure to be here and be exchanging information, not just from Georgia but people in other countries.”The fall workshop on tunnel ventilation will be held in October.

By Stephanie SchupskaUniversity of GeorgiaThe one thing Stanley Kaye didn’t learn at the poultry workshop at the University of Georgia was how to protect his chicken houses from mortar attacks.Kaye, a chicken grower from Alumim, Israel, was in Athens for the tunnel ventilation workshop. Apart from the two mortars that have smashed into his chicken houses, he said that the summertime growing conditions in Israel are similar to those in Georgia with daytime highs between 90 and 100 degrees.last_img read more

Best of the Outdoors 2008: Paddling

first_img FAVORITE PADDLING EVENT Gauley Fest, W.Va.The annual celebration of the dam releases of the Gauley River, Gauley Fest draws boaters from all over the country for a weekend of camaraderie and lighthearted competition.“Gauley Fest is the biggest conglomeration of kayakers in any one spot in the United States, maybe even the world. It always seems to rain at Gauley Fest, so the last couple of years there’s been some quality mud wrestling. And last year Dagger brought out a stripper pole. There were quite a few guys that got onto that thing, and a few women too. You’ve got everything at Gauley Fest.

Recently, he’s been fighting hard for boating access on the Upper Chattooga. How did you get into paddling?In junior high, I went on a rafting trip with an outdoor club to the Lehigh River. It was October and it snowed the whole time. I wore a 6mm wetsuit and wool socks. I was instantly hooked.You’ve been with AW for a while now.I started out of grad school working immediately on dam relicensing issues east of the Mississippi. It was so daunting. I was in meetings for the Cheoah, Nanty, and Tuck at least twice a week. It was intense right away. If you would have asked me at 25 if I would still be doing this job at 32, I would have said no way. But it’s fun, so here I am.Any success stories that stand out in your opinion?The Cheoah, hands down. It’s one of the few projects that I’ve worked from beginning to end, and it’s such a well-rounded victory. I can go paddle that river and know I helped put water in it. It’s very tangible. I’ll be proud of the West Fork of the Tuckasegee too. It’ll be a decade-long project by the time I finally get my boat wet in that river, but it will be worth it.How do you feel about the process surrounding the Upper Chattooga?Honestly, I’m disillusioned by the whole process. I assumed that river management happens based on reason and standards, but the Chattooga has given me a glimpse of the wizard behind the curtain, and it’s not pretty. Ultimately, the outcome will be good and the process has already benefited the environment. Because we have forced them to look at the river and its watershed, the Forest Service found 20 miles of illegal trails and campsites.BEST FLATWATER PADDLELake Jocassee, S.C.This 7,500-acre mountain lake is located at the base of the Escarpment in South Carolina.

This engineered wood radiates heat into space potentially slashing cooling costs

first_imgA sample of a new wood that could reduce cooling costs.  This engineered wood radiates heat into space, potentially slashing cooling costs By Robert F. ServiceMay. 23, 2019 , 2:00 PM Households in the U.S. Southwest spend about $400 per year to cool their homes, about twice the national average. Now, a new type of wood that radiates heat into space could offer some relief. If used on a building’s exterior, such as in siding and roofs, the material could drop a building’s temperature as much as 10°C and reduce cooling costs as much as 60%.“This is just brilliant work,” says John Simonsen, a chemist who specializes in wood science at Oregon State University in Corvallis. However, he says, the new wood could be expensive, and potential energy savings may not offset the price.When most materials heat up, they emit that heat as photons of near infrared (IR) light. The light is readily absorbed by molecules in the surrounding air, trapping the heat—and keeping houses, for example, hot. But in the past 2 years, researchers have devised plastic films and paints that absorb heat and re-emit that energy at longer mid-IR wavelengths, which air doesn’t absorb. If emitted toward the sky, these photons pass unimpeded and dump their energy into deep space. But to use these materials in buildings, engineers need to laminate rooftop or siding materials with the plastics or apply the heat-emitting paints. Click to view the privacy policy.

Countrycenter_img To see if the same attributes could be engineered into a building’s structure, Liangbing Hu, a materials scientist at the University of Maryland in College Park, looked at wood. Wood consists of three main components: cellulose and hemicellulose, which form long strawlike structures, and lignin, which acts as a glue holding the straw strands together. Lignin is a strong emitter of IR light, so Hu and his colleagues knew they had to ditch it.The researchers hit upon a simple chemical procedure. They soaked basswood in a solution of hydrogen peroxide, which chops normally long lignin molecules into small fragments. The fragments diffuse out of the solution and can be washed away. The team then used a hot press, an industrial vise for making wood composites, to compress the remaining cellulose and hemicellulose components together. The result was an engineered wood with eight times the strength of natural wood.The new wood is more than just strong. Stripped of lignin, it turns white, reflecting virtually all incoming light. The new composite also absorbs heat from its surroundings and reradiates it as mid-IR light. That allows the material to cool surfaces to which it is attached by up to 10°C, the researchers report today in Science. The wood doesn’t radiate heat away quite as well as the plastic films. But it’s still cool to the touch, and could make a big difference, Hu says.If this material were applied to the outsides of buildings in the desert Southwest of the United States or other similarly warm climates, the passive cooling effect could reduce air conditioning costs by as much as 60%, the team calculates. The material could also provide welcome relief in developing countries where air conditioning is less common.As promising as that sounds, Simonsen cautions that this relief may not come easily. For starters, wood isn’t regularly used in roofing. It’s flammable and isn’t as durable as asphalt shingles or other standard roofing materials. It also wouldn’t make sense to use cooling wood to side buildings in cooler climates, where it would increase the cost of heating homes in winter.
