Commentary – Gasoline Hike a Good Thing?

Earlier this month, the U.S. National Oceanic and Atmospheric
Administration made headlines when it announced that the winter of
1999-2000 was the warmest one in 105 years. But Great Lakes Radio
Consortium commentator Suzanne Elston thinks that the real news is at
the gas pumps:

Reducing Road Noise

Efforts to reduce road noise pollution are making progress in
Indiana. Last year, Purdue University opened the Institute for Safe,

Efforts to reduce noise pollution are making progress in Indiana.
Last year, Purdue University opened the Institute for Safe, Quiet, and
Durable Highways. The Great Lakes Radio Consortium’s David
Naylor reports:


In the past, measuring road noise meant measuring the sound of a
car’s mechanical systems, primarily engine and muffler noise. Now,
with the development of more efficient engines, researchers have
identified the tires and road surface as the newest problem.


So, Purdue researchers are looking for the quietest combination of
tire treads and pavement. They say the most promising surface so far is
one developed in Europe: a thick layer of asphalt, with pits one and a
half to two inches deep.
It reduces road noise by about 50% and does well in the
freeze-and-thaw cycle. But the major problem is keeping oil and dirt
out of the deep pits.
Lab director Bob Bernhard hopes a double layer of pavement will
help.


“One which has the properties that they think are optimal for acoustics, and then put a second

layer below it, which has bigger spacing. In that way, they can flush the dirt and the things that

are plugging, out of the top layer, where the acoustics are affected, in the bottom layer, and

then flush it out.”


Research on the porous pavement continues in Europe and the U.S.
There are no plans yet for commercial production.

Automakers Unveil Green Concept Cars

Ford and General Motors each plan to unveil new
environmentally friendly concept cars at this year’s North American
International Auto Show in Detroit. The cars are the outgrowth of an
initiative between the federal government and the big three auto
companies to develop a car that could fit a family of five but get 80 miles
to the gallon. The Great Lakes Radio Consortium’s Julie Edelson Halpert has more:

Ford and General Motors each plan to unveil new environmentally friendly concept cars at this

year’s North American International Auto Show in Detroit. The cars are the outgrowth of an

A mid-sized vehicle that triples the fuel economy of today’s cars. That was once only a pipe dream

for domestic auto makers. But after six years of research, they’ve done it. Using a combination

diesel and electric engine, Ford and General Motors have developed cars that get gas mileage up to

eighty miles per gallon. Jeff Coleman is a spokesman for General Motors. He says GM’s car, the

Precept, makes great environmental strides. but one big obstacle remains: cost.


“Many of the technologies that are on the GM Precept are not in high volumes today, and so you’d

expect the vehicle to be quite expensive. And the job over the next few years is to learn more

about these technologies, put these into use in real vehicles that are on the road today.”


Coleman says that as the technologies become more widespread, costs will come down. The auto

companies hope to develop an affordable high mileage car by 2003.

Automakers Accelerate Toward Greener Cars

In the next few months, Honda and Toyota each will launch a
new type of super clean car, called a hybrid. The fact that the
Japanese
are
first to market hybrid vehicles concerns some environmentalists.
They’re
worried that domestic auto makers aren’t moving fast enough on this
promising technology. But in an unusual move, environmentalists are not
chastising the big three. Instead, they’re lending a helping hand. The
Great
Lakes Radio Consortium’s Julie Edelson Halpert files this report:

Bringing Clean Cars to the U-S Market

Two Japanese auto manufacturers soon will unveil a new,
cleaner type of car for the U-S market. It’s called a hybrid. Hybrids
rely
on gasoline, but use an electric engine to double the fuel efficiency
and
emit fewer pollutants. So far, no domestic automaker has come forward
with a hybrid car. And that’s troubling environmentalists. They’re
worried
that the U-S could fall behind its foreign competitors. The Great Lakes
Radio Consortium’s Julie Edelson Halpert has the story:

Commentary – New Pollution Device for Cars

The automobile is a primary source of ground level ozone. As
Great Lakes Radio Consortium commentator Suzanne Elston has
discovered, a U-S company has developed a new product that may one
day have us breathing easier:

The Spirituality of a S-U-V Driver

Surveys show that Sport Utility Vehicles remain a popular choice
among car buyers. But if you drive a small car, or if you are worried
about air pollution, you may not be happy with the increasing numbers of
S-U-V’s on the road. Great Lakes Radio Consortium commentator Matthew
Lawrence agrees, but he thinks S-U-V’s are, on a deeper level, a spiritual
problem:

Cleaning Up the Dirty Diesels

The rule in driving these days seems to be that bigger is better, with
light trucks and sport utility vehicles overtaking the road. But as
automakers bask in their high profits from the pricey vehicles, a new
challenge looms…how to make them more fuel efficient. The trucks guzzle
substantially more gas and emit more pollutants than passenger cars and
the government is putting pressure on automakers to clean them up. Now,
an unlikely candidate is emerging to solve the problem. The Great Lakes
Radio Consortium’s Julie Edelson Halpert reports:

Recycling the Car

Each year nearly 50-million new cars get produced worldwide. And
because it’s home to the Big 3 automakers…the Great Lakes region
accounts for a third of those vehicles. But with all of these new
models coming on the market, what happens to the ones that are ready for
the junk yard? Believe it or not, most of them get recycled. The Great
Lakes Radio Consortium’s Bill Poorman has more:
