The big bad wolf gave straw houses a pretty bad reputation. But it turns out straw bale houses are incredibly strong and energy efficient. The century-old building material is making a comeback as an eco-friendly choice for modern home construction. And these homeowners aren’t afraid of a little wind. One woman is even building a straw bale house in the sometimes cold, blustery climate of the east. Joyce Kryszak tells us her story:

This does kind of start out like a fairy tale. On the edge of the industrial city of Buffalo, New York there’s an ordinary little village. It’s dotted with aging, modest houses.

Carrie Zaenglein used to live here. That is until she lost her village home to fire two years ago. But that didn’t frighten the quiet-spoken young woman away. Zainglein says it just gave her a chance to rebuild. Only this time she’s building her dream home out of straw.

“I’ve always been interested in green building and doing things the environmentally friendly way, so I figured while I had a chance to start over I would do it the way I wanted to do it,” said Zainglein.

But how to go about it? You see, straw bale houses are growing more popular in the southwest. But you won’t find straw house builders listed in the yellow pages of most eastern cities.

So, Zainglein did a little searching on the web and found Dave Lanfear. Turns out, he’s building a company devoted to straw bale house construction. And Lanfear doesn’t care how much he’s teased about it.

“Yeah, I hear the same kind of jokes, I think, the three little pigs… and the same type of questions, but I just have to laugh. Yeah, I hear them,”

Lanfear just digs right in and gets to work plastering Carrie’s two-story contemporary style house.

Lanfear says to do it right you have to get dirty. He fills the wood frame with tightly packed straw bales. Next, the walls are coated inside and out with layers of clay plaster. It’s made with clay dug right from the site. Lanfear says it’s very organic and sustainable. But he says it also withstands the test of time.

“There are homes in Nebraska they didn’t even know that they were straw bale – they were actually hay bale. The walls got open, they were doing repairs and they discovered this hay in there and it actually looked fresh and they were a hundred years old.”

He says that’s because the plaster seals out the moisture but still allows the walls to breathe. That prevents mold and keeps the house sound. It also gets high marks for fire safety. And because the wheat straw is a just a bunch of hollow tubes it creates the air space that makes it a good insulator. Virtually everything about the house is eco-friendly.

The house also has solar heat and power. And it’s made mostly with reused materials. Even the trees cut down to make room for the house were brought inside and used for the framing. And Zaingline says rebuilding on her same small lot near the city means she’s not adding to urban sprawl. She likes to think straw bale houses could be a trend.

“The difference you can make, even though you’re only one person. I think it’s important for everyone to make these changes even if their small.”

Zaingline says her little straw bale house stands up just as well as any house made out of sticks or brick. It might just stand up to the bluster of critics too.

Architecture firms, engineering firms and other energy auditors are getting a lot more business these days. Lester Graham reports… it’s part of a plan to save energy and cut greenhouse gas emissions.

One of the goals of all that federal stimulus money is to make a lot of buildings more energy efficient. First step… get an energy audit. Finding out how much energy a building is wasting has meant a lot of business for people trained to do that kind of work.

Dan Jacobs is with the architecture firm A-THREE-C in Ann Arbor Michigan.

“It’s easily doubled for us in the last year and we’re looking for it to double again as we go into 2010.”

Dan Jacobs says there’s a lot of excitement about renewable energy such as solar panels and rooftop wind turbines … but most buildings waste a lot of energy… so he recommends:

“First thing they want to do is conservation.”

Insulating, replacing windows, and efficient lighting cut energy use. Energy that would still be wasted no matter what fancy renewable energy gadget is put on the rooftop.

A new report indicates social circles have
more to do with what people believe about
climate change than the facts gathered by
scientists. Lester Graham reports on
research presented to the American
Psychological Association:

This report found that while most Americans think climate change is an important issue, they don’t see it as an immediate threat to their lives.

Janet Swim with Pennsylvania State Univerity chaired the task force looking into the issue. She reported to the American Psychological Association that getting people to go green will mean getting past psychological barriers.

For example, a politician might cite scientific facts regarding climate change, but that politician’s party affiliation might be more important to people than the scientific facts.

“Party lines determines to some extent people’s beliefs about climate change. And so, when somebody’s not in your party in the government, telling you something about climate change, you’re already starting with a sense of distrust.”

So Swim says policymakers need to recognize getting people to change their behavior will take more than just science and facts.

When Animals and Airplanes Collide

  • Airport Operations Manager Todd Laps uses pyrotechnics - and sometimes just plain old honking the car horn - to harass birds and keep them away from the airport. (Photo by Julie Grant)

number of bird strikes might give
you one more reason for concern.

If you bite your nails every time
you’re on a plane – the increasing
number of bird strikes might give
you one more reason for concern.
Julie Grant reports on efforts to
prevent airplanes from hitting birds:

Todd Laps probably never envisioned that he’d spend his days harassing
birds. He’s operations manager at the Akron-Canton Airport in Ohio.

(sound of a plane landing)

But for the past few years, he’s started doing everything he can to keep
birds off the runway.

(sound of a horn)

Sometimes he just chases them in a truck while honking the horn.

“If you chase them around enough, they get tired of it, and they leave.
But you may have to drive around blowing the horn for five minutes to get
them to leave.”

(sound of a horn)

It’s not that Laps hates birds. He’s actually trying to save them –
from getting sucked into plane engines. That’s pretty bad for the birds.
It can also damage the planes.

The Federal Aviation Administration says bird strikes have killed more than
200 people worldwide since 1988 – and cost the U.S. aviation industry
hundreds of millions of dollars.

Ever since geese took out both engines in US Airways flight 1549 earlier
this year – leading to that dramatic flight into the Hudson River –
more airports are paying attention to the surrounding wildlife.

Mike Begier is national coordinator of the Airport Wildlife Hazards Program
with the US Department of Agriculture.

He says populations of larger birds – such as geese – are increasing. At
the same time, there are more planes in the air then there used to be.

“So we’re competing for the same airspace. So it’s a probability.
The more times you fly, the more chances you have to strike something.”

Begier says most airports were built a little outside of the city, in
green, wet areas. And those places attract lots of birds and animals.

“Birds may want to stop over there and rest. Airports that do not have
adequate fencing wind up being a refuge for deer or coyote.”

At the Akron airport, they’ve recently cut down 40 acres of trees to make
the area less attractive to wildlife. They’ve also started mowing more
to discourage bugs. Without bugs, there are fewer small mammals and birds.
The folks in Akron think it’s made a difference reducing the number of
accidents.

Airports are not required to report wildlife strikes. Some do voluntarily.
When the FAA opened up its records on collisions between planes and birds
and coyotes and even alligators this year, it looked like the number of
accidents was on the rise at some airports.

But Begier says those numbers don’t provide an accurate picture.
Airports don’t have to report them, so as many as 80% of strikes still go
unreported.

“So when we see these high numbers of strikes, it’s important to
realize that the airports are actually being proactive, that they’re
reporting their strikes – which is a very good thing.”

Begier gives the example of JFK airport in New York. It’s in the top ten
airports nationwide reporting the most wildlife strikes. That sounds bad.
But because JFK voluntarily reported accidents, biologists were able to
figure out part of its problem. When the nearby bayberry bushes were ripe,
they were attracting lots of birds. By removing the bushes, they reduced
the number of accidents.

Researchers are also experimenting with higher tech solutions at airports.
They’re trying laser lights to harass birds away from hangars, using
small radar units to track birds and warn planes of approaching danger, and
using pulsating lights on planes to mimic bird predators.

But for USDA wildlife biologist Rebecca Mihalco, the old fashioned methods
are the most rewarding – at least today. She works at the
Cleveland-Hopkins airport and just caught a red-tailed hawk.

“I’m always excited when I catch a hawk. I guess I’m a kid that
way.”

Mihalco drove the hawk far away from the airport and released it.

But to avoid so many accidents with wildlife, airports will have to do
better than catching them one at a time or chasing after birds and honking
at them.

The Senate sponsors of a climate change
bill say they need more time. Lester Graham
reports Senators Barbara Boxer and John
Kerry asked the Senate leadership to give
them until the end of the month before they
introduce the climate change bill:

The details of the senate bill are still being worked out. The House version included a carbon cap-and-trade scheme to reduce greenhouse gases and raise revenue for clean energy projects.

Environmental groups and labor unions are in favor of cap-and-trade. Jeff Rickert heads up the AFL-CIO’s Center for Green Jobs.

“The climate change bill is a potential stream of revenue to really make the green jobs, the clen-tech industry a reality.”

Business groups say all carbon cap-and-trade will do is make energy more expensive.

“This legislation is a job killer.”

Keith McCoy is a Vice-President with the National Association of Manufacturers.

“So, if you’re a company that’s reliant on natural gas or oil or even coal in the manufacturing process, these companies suffer the most.”

Business suggests the government should just offer incentives for energy efficiency and invest in clean technologies.

The two sides are taking their arguments to the public this month.

A Fight Over the Climate Change Bill

  • Groups are arguing over whether the climate change bill in the Senate will create jobs or kill them. (Photo courtesy of the National Renewable Energy Laboratory)

America has a big decision coming up. We have
to decide whether we want to keep spending our
money on energy from fossil fuel sources such as
coal and oil. Or, do we want to invest more in
renewable energy such as solar, wind, and bio-fuels?

America has a big decision coming up. We have
to decide whether we want to keep spending our
money on energy from fossil fuel sources such as
coal and oil. Or, do we want to invest more in
renewable energy such as solar, wind, and bio-fuels?
Lester Graham reports the next stage for the
national debate will be when the Senate considers
a climate change bill late this month:

The U.S. House has already passed a version of the bill. It includes a carrot and stick plan to cap greenhouse gas emissions and put a price on them. It will mean fossil fuels will become a little more expensive to use. Revenue from the program will be invested in clean energy and energy efficiency projects.

President Obama’s Secretary of Commerce, Gary Locke, says using that money America can reinvent itself and, in the process, create jobs.

“The technological innovations needed to combat climate change, to reverse it, to mitigate it, can spawn one of the most promising areas of economic growth in the 21st century.”

Environmental groups believe that. And labor unions believe it. And some progressive businesses are counting on it. They’ve been joining forces in groups such as the Apollo Alliance, and then there’s the United Steel Workers Union and the Sierra Club’s Blue/Green Alliance.

Leo Gerard is the President of the United Steelworkers.

“We need a climate change bill that is focused on creating jobs and cleaning up the climate. With a lot of conservation, a lot of investments in the newest technologies, what we’ll end up doing is taking a huge amount of carbon out of the atmosphere and creating a lot of good jobs.”

Business groups say all carbon cap-and-trade will do is make coal, gas and oil more expensive.

“This legislation is a job killer.”

Keith McCoy is a Vice-President with the National Association of Manufacturers. He says the government should not penalize businesses that rely on cheaper fossil fuels.

“So, if you’re a company that’s reliant on natural gas or oil or even coal in the manufacturing process, these companies suffer the most.”

Business says drop cap-and-trade. And just use the carrot. The government should just offer incentives for energy efficiency and invest in technologies such as nuclear power and carbon capture and sequestration for coal-burning industries.

So the two sides are rallying the troops.

The unions and environmental groups are urging their members to push for cap-and-trade for the sake of the planet and for the promise of green jobs.

Business groups are launching TV ad campaigns against it. Oil companies are using a front group called Energy Citizens to hold public rallies oppsing cap-and-trade. They raise the spector of high gasoline prices and higher electricity bills and throw in the threat of losing as many as 2.4 million jobs.

Ed Montgomery is President Obama’s Director of Recovery for Auto Communities and Workers. He says a clean energy policy is not going to hurt the US, it’ll save it.

“Something’s gone wrong. Our manufacturing sector isn’t able, and hasn’t been able to compete and continue to create new and effective jobs. And what a clean energy policy opens up for us is a whole avenue forward. It’s a way to create both new jobs, to open up new avenues of competitiveness, the competitiveness that uses the strengths of our workers – who know how to make product.”

But first, the debate will devolve into shouting matches about whether global warming is real and, if it is, whether cap-and-trade will do anything to slow it. There will be distortions on both sides about the end of the economic good of the country, and the climatic end of the world as we know it.

And because of all the complexities, the arguments will leave a thoroughly confused public about whether we should use government policy to shift from reliance on carbon-emitting fossil fuels to banking more on renewable energy.

There was a time – not that long ago –
when a lot of the National Parks in the
country were strapped for cash. They
were cutting staff and cutting services.
But, Mark Brush reports, now Congress
is investing more in the parks:

It started changing in the last year or two of the Bush Administration. The Bush White House realized that the National Park System was coming up on its 100th Anniversary in 2016.

No one wanted the Centennial marred by crumbling roads or Parks that were understaffed. So Washington pledged to increase the overall budget for the National Park Service by 100 million each year until the Centennial.

And folks like Tom Ulrich say Congress has been making good on that pledge. He’s the deputy superintendent at Sleeping Bear Dunes National Lakeshore on Lake Michigan.

“A few years ago our discussions weren’t, you know, ‘Well, we got a little bit of extra money how are we going to spend that?’ They were, ‘We have to cut from last year. What are we going to cut?’ And so it’s nice to have those discussions change.”

Ulrich says a lot of National Parks are also getting some money from the stimulus package passed earlier this year.

When Congress returns from its August

the National Park Service. If confirmed,
Jonathan Jarvis will have some tough
decisions to make about what kinds of tourist
attractions to allow in the parks. Jessica
Robinson reports on the latest proposal to
add aerial sightseeing tours at a National
Park in Oregon:

Nearly 8,000 years ago, Mount Mazama spit out ash and lava and collapsed in on itself, leaving what became Crater Lake.

Park Superintendent Craig Ackerman says the stillness of the blue waters is matched only by the stillness in the air.

“You can stand on the east flank of Mount Scott and you can absolutely hear the wind whispering through the white bark pines and the hemlocks.”

It’s true – there are moments when it’s just your footsteps, the wind, and the birds.

But then, at the popular viewpoints, there are the other species you find at many national parks: like Toyotas, Winnebagos, and Harleys.

(sound of a motorcycle)

Now, a company up the road in Bend, Oregon, has a proposal that could add one more sound to the mix.

(sound of a helicopter)

Leading Edge Aviation has put in an application to offer as many as 300 helicopter tours a year around the edge of Crater Lake. Travis Warthen is the company Vice President.

“I mean, it really is a majestic sight to see. And, the noise level is less than that of a car – you know, definitely motorcycles, RVs, the bus tours. I mean, it’s difficult for us to understand the huge opposition.”

At 1,000 feet up, he says, the choppers sound to someone on the ground, about as loud as a normal conversation.

“So you say, ‘it’s already compromised by the motorcycles and the motor-homes, so what’s wrong with a little more?’”

That’s Scott Silver. He’s executive director of Wild Wilderness, a group he started with a friend to monitor motorized recreation on public lands.

Silver sits in his back yard, just across town from the aviation company proposing the tours. He says National Parks should provide a respite from some of the noise we’re used to in everyday life. As he explains this, a passing helicopter interrupts our interview.

(sound of a helicopter)

“That’s actually the helicopter from the hospital. But, okay, it’s no big deal really in town. It’s just a distraction. But everyone still stops and looks up if it’s flying over a national park. And really, why should visitors have need to look up to listen to sounds over head?”

National Parks advocates worry that helicopter flights at the Grand Canyon, Glacier National Park, and others are making commercial tours the norm for parks visitors. They’re hoping Obama’s pick to lead the National Park Service, Jonathan Jarvis – a former Crater Lake biologist – will reverse the trend.

But here’s the rub: there’s nothing stopping you from flying over any National Park right now – if you have a private plane.

And Jeff Allen, head of the Crater Lake Trust, wonders if that’s fair.

“There’s a part of me that feels like, if you’re going to allow it at all, I’d rather see regular folks be able to have that experience, than have you have to go out and own a plane or know someone who owns a plane.”

Aerial tours of Crater Lake won’t be offered any time soon though. There’s a hefty backlog of similar requests at other parks – and they’ll all have to go through not one but two federal bureaucracies: the National Park Service and the FAA.

Turning Clunkers Into New Cars

All those clunkers are working their
way toward the final melt-down at
a steel mill. Lester Graham reports
you’ll see the steel from those clunkers
again:

The steel from those clunkers from the “Cash for Clunkers” program will eventually be melted down and used again.

Bill Heenan is the President of the Steel Recycling Institute. He says it’ll be a few months before that scrap gets recycled.

“It takes some time for that old automobile, the clunker in this particular case, to work its way through the dismantling system and then through the shredding system and eventually to the steel mill.”

Scrap yards can remove things such as fenders or hubcaps for used parts, but what’s left – including the engines – goes to the shredder.

Bill Heenan says those 700,000 clunkers won’t mean a glut of scrap steel.

“Let’s say there’s a ton of steel in each one, you’ve got 700,000 tons. That seems like a lot. But in a given year, we recycle 80-million tons.”

That 80-million tons of scrap is melted down and becomes the bulk of new steel products in the U.S., including new cars.

Recycling Your Ride

to dead cars, regardless of how they
die. Shawn Allee looks at
how car recycling works and who’s

We’ve all heard over and over again about that government program ‘Cash for Clunkers.’ It’s got drivers thinking about what exactly happens to dead cars, regardless of how they die. Shawn Allee looks at how car recycling works and who’s trying to improve it:

You might not think about it this way, but your car just might be the biggest thing you own that gets recycled.

I mean, someday you’re going to junk it, or maybe some future owner will. Anyway, I’m out in front of a car shop in my neighborhood, and with the health of cars in mind, I thought I’d ask some people around here, percentage-wise, just how much of a junked car gets recycled?

“I would say maybe, like, 5% of the car.”

“I’ll say, 20% – 30% probably, of a car.”

“I guess the recycled one could be 30% of the car.”

“I guess, like, 50%.”

“About 70%.”
++

In my little unscientific survey here, it turns out that most people are giving a pretty low estimate of how much of a junked car ends up being recycled.

The auto industry and the federal environmental protection agency say about 80% of the junked car gets recycled. The rest heads to landfills. That sounds pretty good, but that means we bury about five million tons of junked car pieces each year.

To understand why they can’t recycle even more of the car, I’m going to talk with Jim Watson.

He runs ABC Auto Wreckers in a suburb just south of Chicago.

“We don’t want to landfill anything. The objective is to take the vehicle, process it and have all the parts be used.”

Watson shows me his shop where he pulls parts for the used market. A dozen workers lift hoods, twist tires, and pull out stuff I don’t even recognize. It’s like an assembly line in reverse.

“They do an analysis and inventory each of the parts of the car that have a probability of sale and then they harvest or pull those parts off the car.”

Watson and some of the bigger auto wreckers have parts-scrapping down to a science, but it’s expensive to keep pulling parts and keep space open for scrap yards.

Eventually, Watson’s pulls off everything usefull and he’ll send it to a car shredder.

“A machine that beats it apart and shreds the car into small fist-sized or hand-sized components.”

Recyclers can pull out big shreds of steel and aluminum, but about 20% of the car is left-over. This shredder residue gets tossed into landfills. But scientists are thinking about how to recycle this shredded mess.

One works at a lab at Argonne National Laboratory near Chicago.

“This is what shredder residue looks like.”

Dr. Bassam Jody reaches into a cardboard box and scoops a jumble of car seat foam, metal cable, wood, and shards of plastic.

Jody says shredder residue is a recycler’s nightmare.

“Maybe there are more than twenty different kinds of plastics. I tell you, plastics are generally incompatible, they don’t like each other and they don’t work together very well.”

Jody is developing machines to safely clean and separate all this stuff. It’s tough science.

Jody: “The more things you have in the mixture, the harder it is to separate. The trick is, you have to do it economically, and to produce materials that can be used in value-added products.”

Allee: “What can you make out of them?”

Jody: “Car parts. For example, this is a seating column cover.”

Jody says he gets a kick out of his work. He might just squeeze a bit more good out of our cars.
