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.

Every year there are about 1.5 million
deer-car accidents. Now highway officials are
testing a new system to cut down on those
accidents. Rebecca Williams has more:

There are some animal detection systems that use lasers or infrared motion
sensors. But those systems can be tripped by tumbleweeds or small animals.

In Colorado, highway officials are testing a new device.

Nancy Shanks is with the Colorado Department of Transportation. She says
they’ve buried cables along each side of the highway. The cables emit an
electromagnetic field. When an animal crosses a cable a warning sign with a
picture of a jumping deer lights up.

“It will detect a change in the field to the tune of a large animal. The system
will not pick up a smaller animal – a skunk or a rabbit, mouse.”

This cable system isn’t cheap. The pilot project costs 1.2 million dollars.

But Shanks says if this system works out, the price should come down a bit
over time.

Hydrogen Explodes Onto Car Scene?

Within the next few years, you might see a new type of car in dealer
showrooms… one that runs on hydrogen. Many engineers and car company
officials predict that hydrogen vehicles will replace gasoline power in
the next 10 to 15 years. But lots of people think hydrogen is too
explosive and wonder if a hydrogen-based economy will be safe.
Julie Grant reports:


Sales associate Chris Beckham hears a lot of concerns about the new
Honda fuel-cell car on display at a recent car show:


“I know a lot of people are kind of worried about the safety of the
hydrogen vehicle because it’s basically like running on an atom bomb.”


Honda fuel cell marketing specialist Steve Ellis rolls his eyes when he
hears comments like that. The Cold War-era hydrogen bomb comes to mind
for people because it’s one of the few times they’ve heard the word
“hydrogen” used in conversation. Another time is when people talk
about the hydrogen-filled blimp, the Hindenburg. Ellis wants to
clear the air about the Hindenburg disaster.
The huge zeppelin burst into flames, and a lot of people blame the hydrogen:


“But history has now shown that it was the coating, the covering of the
material that actually was sustaining the fire. The hydrogen itself of
course being flammable, whatever that cause was, it did ignite. But
the flame was sustained by the coating. That’s what people see.”


Ellis says hydrogen has gotten a bad rap:


“When in reality, science has proven that it wasn’t the guilty party.”


(Grant:) “But it is a very flammable substance?”


(Ellis:) “Sure. As is gasoline.”


There’s still controversy over whether the hydrogen or the coating
caused the Hindenburg to burn. Regardless. Many energy experts say
hydrogen is more flammable then gasoline, but Ellis says the dangers of
a hydrogen fire aren’t any worse then a gasoline fire, they’re just
different.


He says people are used to dealing with liquid gas at the fueling
station. But in some ways, hydrogen could be considered less dangerous
then gas. When gas spills it pools up on the ground, and if someone
drops a cigarette – yipes! – it could be a long day for firefighters.


But hydrogen goes into cars in gaseous form. If there’s a hydrogen
leak, Ellis says it’d be easy to put out a fire:


“So with, you know, fire systems at the station, if there’s any
detection of a flame or any incident like that, as soon as the source
is shut off, the fire’s out, it’s gone. First responders and many fire
departments have said they feel like responding to a hydrogen fire…
it’s like, by the time they’ll get there, they’ll be nothing to put out.
It’ll likely have taken care of itself.”


That’s one advantage of using a light-weight fuel like hydrogen: it
dissipates quickly into the air because it’s lighter then air. But
because it’s so light, each cubic foot doesn’t pack that much energy.
That’s why cars can’t store that much hydrogen in the tank.


Hydrogen-expert Paul Erickson says that low energy content also creates
other safety problems. Erickson is director of the Hydrogen Production
and Utilization Lab at University of California-Davis. In order to
make cars that hold enough hydrogen to travel a respectable distance
between re-fuelings, he says they have to use a lot of pressure to
squeeze enough hydrogen into a tank:


“It’s just very difficult to get the range out that you’d like. And so you
end up having to pressurize the hydrogen to 3,000, now we’re up to
5,000, now up to 10,000 pounds per square inch. I wouldn’t want to sit
on a 10,000 psi tank of anything, much less hydrogen.”


Erickson says car companies understand the dangers of combining
hydrogen’s high flammability with high pressure in the tanks. They
don’t want any hydrogen to escape from the tank if there’s a collision
and they don’t want the tank to blow up. So, the tank is probably the
strongest component on the hydrogen vehicles being built today.


That’s not the case with regular gas cars. Steve Ellis at Honda says
they won’t release too many consumer vehicles to start. One reason is
to slowly get people used to handling hydrogen safely.

Insurance Rates Driving Sprawl?

  • Insurance rates are often lower if you live in the suburbs. (Photo courtesy of the USDA)

People who live in the city pay higher insurance rates for cars and homes
than people in the suburbs. Often it’s a lot more. The insurance industry
says it’s using the fairest method. The GLRC’s Lester Graham reports
that method might contribute to urban sprawl:


(Sound of car starting)


We’re taking a little drive and Brandi Stoneman is showing me where she used to live.
It’s just two-and-a-half miles from where she works. But… she met a guy… they
dated… they fell in love… and after a while decided to move in together.
His house was bigger. So, Brandi moved from her home near downtown
and out to his house 15 miles out into the suburbs.


When she told her insurance agent… she got a surprise. Her auto
insurance rates dropped… a lot.


“It almost was in half when they—when I told them I’d moved and
changed and it almost dropped in half. Of course I was excited, but it
was amazing. It was a huge difference.”


“Did you ask them why?”


“I did ask them why and they said, of course, that it was the area that I
lived in. It went by the zip code and it didn’t have really have much to do
with the fact that I was farther away from work.”


So, instead of five miles to work and back… she drives 30 miles… to the
same downtown location, but that wasn’t the only surprise. She kept her
old home in town… so, like her boyfriend, she still needed to buy
homeowners insurance.


“And when we both were looking and shopping for insurance rates, I
spent about three-to-four hundred dollars on my premium on a house that
was almost half the price of his, and that was, again, because of where I
lived and the zip code and the area that I live in.”


If you live in the city… this might sound familiar. You probably know a
colleague or friend in the suburbs who’s paying a lot lower insurance
rates. Stoneman lives in Michigan. That state’s Office of Financial and
Insurance Services spokesman, Ken Ross, says it’s typical of insurance
rates across the country.


“Our urban population centers have experienced higher rates for both
home and auto insurance. That is a function of insurance companies
pairing the higher costs associated with living in an urban environment, higher
concentration of people with higher losses and those losses are paired
with rates being filed and ultimately premiums being charged to
consumers who live in those areas.”


And the regulators say that’s a pretty fair way of doing things. The
insurance industry also thinks it’s fair.


Peter Kuhnmuench is with the Insurance Institute of Michigan.


“Largely because of the density of the population, the incidents of
collision, the incidents of theft are much higher in an urban area than
they are out in the outlying suburban areas.”


Kuhnmuench says if people choose to live in the city, they should expect
to pay higher insurance rates. He agrees that the lower rates in the
suburbs might be an incentive to move there.


“Well, I would certainly believe that cost factors for insurance would be
a contributing factor to your decision to move from the city to the
suburbs. Obviously, higher insurance rates reflected in the city could be
one of those contributing factors, I guess, Lester, but overall those rates
pretty much reflect the underlying costs to provide the coverage in those
areas.”


Different state legislatures have considered laws that would make
insurance rates less dependent on where you live, but those kinds of bills
usually don’t even make it to a vote because legislators don’t want to
anger suburban voters by making them subsidize urban insurance costs.


So instead, more people move to the suburbs and ironically, everybody else
subsidizes the cost of new suburban streets, more lanes of highways, and
other infrastructure costs associated with the sprawling suburbs and
accommodating the people who commute to the city.


And while the lower insurance rates encourage a move to the suburbs,
big city mayors say the higher rates in urban areas discourage
redevelopment in the city. Those mayors, urban legislators, and
advocacy groups lobby state legislatures to find an insurance rate
structure that doesn’t penalize those people who choose to live in the city
and reward those who spread out to the suburbs.

INSURANCE RATES DRIVING SPRAWL? (Short Version)

Some big city mayors and urban legislators say insurance rates are unfair
to people who live in cities. The GLRC’s Lester Graham reports, state
legislatures are reluctant to change insurance rate structures in fear of
angering suburban voters:


Insurance rates are higher in cities than they are in suburbs. Often
they’re much higher. Peter Kuhnmuench is an insurance industry
spokesman with the Insurance Institute of Michigan. He says there are
more risks and more insurance claims in the cities that drive up the costs.


“We see a higher incidence of fire and burglary and theft in the urban
areas typically than you do in the suburban areas.”


And although suburban residents typically drive their cars farther to
work, drivers in the city have more collisions and theft claims.


Legislators in cities want the insurance costs tp be spread out across a wider
population, but suburban legislators don’t want their residents to have to
subsidize urban insurance rates. Those in the city say the irony is:
through tax dollars, their residents are forced to subsidize more lanes of traffic for
the suburbanites who commute to work in the city.

Grade Crossings a Problem for High Speed Rail?
