Despite the recent defeat in Congress of a measure that would have raised fuel efficiency standards, carmakers are still feeling pressure to design and produce less polluting vehicles. Some companies are betting on new technologies to make those dramatic pollution reductions. And a debate’s emerging over how best to get there. Some observers say what’s at stake is nothing less than the future of the automobile. The
Great Lakes Radio Consortium’s Julie Halpert filed this report:

It’s a clear battle between emerging technologies: what’s available now: hybrid engines, versus fuel cells, which aren’t due for at least ten years. Hybrids use current technology, a gasoline engine, and add an electric engine for additional boost. A hybrid car typically gets double the mileage of a non-hybrid.

Toyota and Honda have both opted for the quicker path. They’ve been offering hybrid cars now for the past few years. Toyota’s Prius is a sedan. Honda opted for a sporty, two-seater, the Insight. But whether sporty or practical, Honda’s Andy Boyd says consumers embraced the new engine.

“We had a great reaction to Insight – people really excited by the technology, very accepting of it. It’s very transparent technology, easy to use and we think it’s ready for prime time.”

Prime time for Honda means putting the hybrid engine on a more practical vehicle, which they’re doing. The Honda Civic is a company best seller. The hybrid Civic goes on sale in April. Priced around $20,000 the Civic will get 50 miles per gallon. And Boyd thinks it will result in even broader acceptance of hybrid technology.

A domestic automaker is also jumping on the hybrid bandwagon, hoping to broaden the hybrid’s appeal. Ford Motor Company will launch the hybrid Escape sport utility vehicle later next year. Ford’s Jon Harmon says that’s an even better vehicle choice than the Japanese offerings.

“Most of those vehicles have limitations because they’re such small vehicles and we think that by giving a vehicle with more functionality that customers are looking for, like the Escape HEV, that we’re really going to open up that market.”

The hybrid Escape will get 40 miles to the gallon in the city, twice the mileage of its gasoline engine counterpart.

But while hybrids make big dents in reducing pollution, they’re not considered the final answer to the environmental problem. The more promising contender is fuel cells.

“In a minute we’ll introduce a revolutionary concept, so revolutionary that we believe it’s no stretch to say it could literally reinvent the automobile.”

General Motors President and CEO Rick Wagoner unveiled his company’s first fuel cell car prototype, the Autonomy, at the North American International Auto Show earlier this year. Fuel cells run on a mixture of hydrogen and oxygen. They emit only water vapor and heat, so they’re essentially pollution free. They’re also extremely fuel-efficient. But even the GM fuel cell car won’t be available for at least ten years. That’s because the technology still faces many financial and engineering hurdles.

Even so, GM spokesman Bill Nowak says that investing in fuel cell technology is smarter than putting money in less effective, near-term hybrids.

“It has a fair amount of potential to improve your efficiency but you’re adding another power plant. A hybrid combines an internal combustion engine with an electric motor so there’s some cost factors involved in that. That’s why we think the best technology by far is the pure fuel cell.”

Still, many experts and other automakers don’t expect to see fuel cells on the road very soon. David Hermantz is with Toyota’s Technical Center. He says it could take 20 or 30 years. And he’s concerned that by pushing for fuel cells; GM’s trying to postpone any near-term actions to reduce auto pollution.

“GM’s interim image appears to be that ‘leave us alone for now and we’ll get to fuel cells in the future’ and we think we need some kind of progressive path to get to the future.”

That path for Toyota is a commitment to offer 300,000 hybrid vehicles a year worldwide beginning 2005. Honda also will continue promoting hybrids. Again, Honda’s Andy Boyd.

“In the long-term, fuel cells are probably going to be the answer, but again, if we’re looking out about 30 to 40 years, do we want to wait that long to try and do something about fuel efficiency and reducing emissions? Reducing fuel consumption is the greatest thing we can do to cut emissions, so we’re trying to do that.”

Still, the federal government currently prefers the long-term option. The Energy Department recently scrapped an existing hybrid research program and instead decided to fund an effort to develop a fuel cell powered vehicle.

That concerns Mike Flynn. Flynn runs the University of Michigan’s office for the study of automotive transportation in Ann Arbor, Michigan. He says the government’s decision, which comes amidst a slump in the auto industry, will take pressure off automakers to pursue hybrids.

“They have tremendous demand on their resources right now, so why would I do other than what the government is telling me I should be doing, which is this longer term bet on fuel cells which I may be able to defer a little bit in the first few years and use my resources elsewhere.”

Flynn’s also worried about focusing only on fuel cells. He says that if another technology wins out, the domestic auto industry could be left behind.

But GM’s Bill Nowak says that’s unlikely. And he’s convinced that ultimately, the company’s bet on fuel cells will pay off.

Cleaning Waterways From the Bottom Up

Polluted sediments sit at the bottom of rivers and lakes across the Great Lakes region. They can affect water quality, wildlife and human health. More than 40 highly contaminated areas in the region have been identified by the EPA’s Great Lakes Office, but so far only about half of those sites have been cleaned up. This fall, dredging is taking place in at least three of those hot spots – all on rivers. The Great Lakes Radio Consortium’s Karen Kelly reports on the challenges of cleaning up a river bottom:

Polluted sediments sit at the bottom of rivers and lakes across the Great Lakes region. They can affect water quality, wildlife and human health. More than 40 highly contaminated areas in the region have been identified by the EPA’s Great Lakes Office.
But so far, only about half of those sites have been cleaned up. This fall, dredging is taking place in at least three of those hot spots, all on rivers. The Great Lakes Radio Consortium’s Karen Kelly reports on the challenges of cleaning up a river bottom.


(Sound of dredging)


Geologist Dino Zack stands on the steps of a mobile home overlooking the St. Lawrence River. He watches as barges glide in and out of an area contained by a 38 hundred foot long steel wall. Each barge carries a crane that periodically drops a bucket into the river bottom, pulling up sediment contaminated with PCBs. The goal is to remove 80 thousand cubic yards of contaminated sediment. Zack’s trailer is the EPA headquarters for the dredging project. He’s an independent contractor working for the federal government, which is spearheading the operation. And he’ll spend the next couple of months watching the Alcoa-Reynolds Company remove the chemicals they once dumped in the river.


“I’ll observe them while they’re collecting their data to make sure they’re following the work plan. Then, I’ll bring all the data back, assemble it into tables and review it.”


Zack isn’t the only one keeping a close eye on the dredging project, which began in June.
There’s another EPA scientist here, as well as two members of the Army Corps of Engineers who are supervising the work. There’s also a representative from the St. Regis Mohawk reservation, which is downriver from the contaminated area.
The EPA ordered Alcoa-Reynolds to clean up the pollution in 1993. The PCBs were present in a flame retardant liquid the company used in its aluminum smelting process.
Over the years, the liquid drained into the river, contaminating sediments along the shoreline. The most polluted area contains 2000 parts per million of PCBs. That equals about one bad apple in a barrel-full. The goal is to leave only one part per million of PCBs in the sediment. Anne Kelly is the EPA’s project director for the site.


She says achieving that level in a river environment is a challenge.


“One of the biggest problems with dredging a river is that you’re working without really seeing where you’re working. The other problem is the issue of re-suspension, that whenever this bucket hits the sediments, it stirs up sediments and then it settles out again.”


One of the biggest concerns is that the disturbed sediments will move downstream.
In this case, they’d only have to travel a mile to reach the drinking water intake for the St. Regis Mohawk reservation. That means toxins could make it into the drinking water.
Local people have also expressed fears that the PCBs could contaminate the air as well.
The dredging project was temporarily suspended this summer when residents on nearby Cornwall Island complained of respiratory problems. But air quality tests found the dredging wasn’t to blame. Ken Jock is the tribe’s environmental director.
He says in addition to air and water quality concerns, the local people would like to see a healthier fish population. Some species have been contaminated with PCBs. And he says that’s why the tribe supports the dredging.


“We know the PCBs will be there in a thousand years and we’ll be here, and we’ll still want to eat the fish. So we think that any solution has to be a permanent solution.”


The Alcoa-Reynolds Company had wanted to place a gravel cap over the chemicals rather than dredge. But the EPA ordered them to remove the PCBs. Rick Esterline, the company’s project director, says they’re fully cooperating with the government.


“You’re required to clean it up, that’s the rules and regulations that we have in our country. Whether they come at you with court orders or whether you do it, it’s still you have to do it.”


The project is expected to cost the company 40 million dollars. That includes the eight million dollar reinforced steel wall around the contaminated area. Alcoa-Reynolds is also using a special electronic bucket to remove the sediment. The EPA’s Anne Kelly says this has become the bucket of choice for Great Lakes dredging projects.


“Based on the information that will be transferred to the operator on the barge, he’ll know if that bucket is completely sealed, which is very helpful because a clamshell bucket will begin to close and hit a rock… he won’t know it’s still open partially and begin to pull that up through the water column with materials basically pouring out of it.”


Kelly says every cleanup project requires a different approach. In Michigan, General Motors is using an environmental bucket and silt curtains to dredge the Saginaw River.
Engineers in Michigan’s Pine River built a steel wall and emptied out the water inside before dredging. The dredging in the St. Lawrence is expected to finish in November.
And it’s possible it won’t reduce the PCB levels to one part per million. The cleanup at the nearby General Motors plant fell short of that goal. If that happens, the EPA will require the company to cap the river bottom – and monitor the sediments, the water and the fish indefinitely. For the Great Lakes Radio Consortium, I’m Karen Kelly.

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.

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:
