The new General Motors, which recently emerged from bankruptcy, wants to create a clean, green image with its Chevy Volt electric car. But GM might have a bit of an environmental PR problem on its hands. Tamara Keith explains:
Automakers used to use mercury switches for lights and anti-lock brakes. But when old cars are scrapped and melted down, those parts turn into toxic air pollution.
So automakers and environmental groups created a program to recycle the mercury.
More than half of the mercury switches still on the road are in GM’s cars. But, since filing for bankruptcy, GM stopped paying into the program.
Rich Bell is president of the program, and he also works at Ford.
“None of our members are interested in paying for GM’s environmental legacy issues, and so we’re looking for a path forward, and we’re kind of in the midst of that now.”
In a statement, the new GM said those cars with mercury switches were made by the old GM.
The new GM that emerged from bankruptcy is not responsible for those old switches.

Even though General Motors has filed for bankruptcy, Rebecca Williams reports the company is still dreaming big:
Someday you might be able to power your radio through your car’s paint.
Christopher Webb is GM’s senior creative designer.
He says GM’s research teams are giving some thought to solar powered paint. He says it might start with tiny solar cells called quantum dots.
“You could suspend these solar cells in a resin system or a waterborne or solvent carrier and spray it over the surface of the vehicle. Technically the entire surface of the vehicle could become almost a solar conductor.”
Webb says nobody knows exactly how this might work yet. But he says he’s confident that GM will continue their research into new technologies like this even with the bankruptcy announcement.
Something else that’s being talked about is using volcanic rock in paint. It could be a coating that would reduce a car’s interior temperature by reflecting heat – so you could use the air conditioning less often.

President Obama has outlined his plans
for the struggling auto industry. They
include restructuring GM and Chrysler
as well as help for auto workers and
communities hurt by slumping car and truck sales. Lester Graham reports lost in the details was the President’s bigger plan:
In one sentence President Obama summed up his vision for the U.S. auto industry.
“I am absolutely committed to working with Congress and the auto companies to meet one goal: the United States of America will lead the world in building the next generation of clean cars.”
Some analysts say the market should decide whether consumers want fuel-efficient, clean cars. They point to headlines noting hybrid car sales fell off a cliff since gasoline prices went down.
But J.D. Power and Associates’ Michael Omotoso says yeah, hybrid sales are down – but not as much as everything else.
“Hybrid sales are actually doing well compared to overall sales.”
Hybrid sales in February were down 29% from last year, but overall light vehicle sales fell 40%.
Omotoso says hybrids are still selling because people expect gas prices will go up as the economy recovers.

If you want a clean electric vehicle to cruise the highway today, you really only have one option – a small, Silicon Valley company named Tesla. Tesla has plans to be a big player in the auto industry, but so far the company has only built a few hundred cars. Dustin Dwyer looks at whether Tesla can make it in one of the toughest industries around:
If you’re trying to get attention for a new vehicle, a big auto show is one of the best places to get it.
And even this year, as GM and Chrysler hobbled into the Detroit auto show on federal life support, and all carmakers scaled back, there was still a lot of hype.
Here’s GM’s introduction for the Chevy Volt.
“Ladies and gentlemen, the future of automotive transportation has entered the building.”
That’s how the big players make their announcements.
Tesla is not a big player.
CEO Elon Musk made his big announcement in a hotel conference room in front of a bunch of geeky auto analysts.
“A big announcement that I’ve just gotten this morning permission this morning to make is, um” (takes drink)
Here he takes a drink of his water.
“…that Daimler has given us permission to acknowledge that they are the automotive partner that we’re working with.”
That means Tesla is going to help make an electric version of Daimler’s tiny Smart Car.
Musk is not much of a salesman. But maybe he doesn’t have to be. While all the big carmakers are seeing huge sales drops, Musk says Tesla sales keep going up.
“And, well, actually we can’t produce them fast enough and we’re sold out through November of this year.”
Now, Tesla – at most – makes 30 vehicles a week. And its only car, a sporty roadster, sells for more than $100,000.
A company like GM sells thousands of cars a week, and people who aren’t movie stars can actually afford some of them.
But Musk says he wants Tesla to be more than just a small time player.
So now the company is working on a four-door sedan that will sell for about $50,000 – still pricey for most of us, but half the price of its two-seat roadster.
Here’s the thing though, right now, Tesla has the electric vehicle market all to itself. But all the big companies are working on their own electric cars.
So when Tesla comes out with its four-door sedan, the competition will be much tougher.
Michael Robinet is an auto industry analyst with the firm CSM Worldwide. He says Tesla’s small size is a problem.
“Economies of scale is one of the main drivers of this industry to get cost out of the vehicle and be competitive. And that’s where the major vehicle manufacturers are going to have a leg up in the future.”
Some who follow the auto industry think Tesla’s future could be as more of a partner to existing companies, like what Tesla is doing with Daimler.
But Elon Musk insists Tesla will continue to make its own cars. And it can succeed.
“You go through sort of stages of denial, I guess. You know, when we first said we’d make this car, people said you can’t make this car. It’s not going to work, the technology’s not going to work, and even if the technology works, nobody’s gonna buy the damn thing. And we’ve shown, hey, we can make the technology work and people really want to buy it. So, okay, then they go to the next stage, ‘Oh, well, sure, okay, people will buy that car, but they won’t buy a sedan.’”
Tesla plans to unveil the new sedan later this month (March 26). The car is expected to go on sale in 2011.
In the meantime, Tesla has not been completely immune to all the problems facing the auto industry. Tesla had trouble raising money last year to finance the new sedan. So it turned to the federal government for a 350 million dollar loan.
At least in that one sense, Tesla is already acting like a major player.

She’s a reporter who’s been covering the
preview of the Detroit Auto Show (opens
Saturday January 17th). She says
Honda, which started this hybrid trend,
hasn’t done much lately, but it is now:
Lester Graham: They’re paying a lot of attention to the Detroit Auto Show this
year because of the bailout and because of the new green cars that are being
displayed. Julie Halpert’s been covering the Auto Show. Julie, there’s a lot of
talk about the domestic automakers bringing on board hybrids and plug-in
hybrids in the near future, but it appears the Japanese automakers are coming
out ahead.
Julie Halpert: What’s interesting is the Japanese automakers feel it’s more
important in the near future to focus on regular hybrids. For example, Honda is
coming out with a new version of its Insight, that is comparable in size to the
Prius. And, it’s going to be the most affordable Hybrid. Priced under $20,000,
which makes it very attractive. Their argument is, these electric cars are
interesting, but there’s a lot of work to be done on the battery, and, so they would
rather see lots of people in hybrids, near-term. They think that’s going to make a
bigger difference environmentally than coming up with these plug-in hybrids,
which are going to be more expensive, and aren’t going to be offered for the next
couple of years.
Graham: If oil prices stay low, I’m wondering if domestic automakers will stay the
course of these more energy efficient cars. It sounds like they want the
government to force consumers into that market.
Halpert: Well, the government’s obviously placing a priority on this. And what
they’re very much hoping is that the government fuels demand by creating tax
incentives for these vehicles – they have the ability to do that, Congress has the
ability to do that. I think they’ve invested so much now, there’s really no
reversing course. The problem is that customers are very fickle. If gas prices
are low, they’re going to go back to their conventional internal combustion
engines. When gas prices were high, this past summer, there was a huge cry for
these alternative, more fuel efficient vehicles. The problem is that automakers
need to plan months and months in advance to bring out these vehicles. So
now, they’re on course to do that, it would be very difficult for them to switch
course at this point.
Graham: While Honda’s coming out with this new version of the Insight, Toyota’s
coming out with a third generation of the Prius, GM’s trumpeting the Volt, Ford is
going after smaller engines with turbo power. Why are they taking that
approach?
Halpert: Well, it’s actually quite a prudent approach. They’ve got this hybrid
Ford Fusion, which gets 41 miles per gallon. And, they’ve got this super turbo-
charged engine, which can boost fuel efficiency by 20-30%. And, their argument
is, let’s use more conventional motors to do this, because it gets into an
affordability issue. They can basically provide the power of a V8 engine in a V6
engine. And, consumers still want that power. They want low costs. So, they
figure, this new technology can go quite far in getting a lot of fuel efficiency and
not requiring consumers to pay this up-front premium that other hybrids cost.
Graham: That’s Julie Halpert, who’s been covering the Detroit Auto Show.
Thanks, Julie.

Car makers are at the North
American International Auto Show in
Detroit to show-off their hybrids,
and coming plug-in hybrids. Lester
Graham reports:
GM, Ford and Chrysler have all built hybrids and have plans for more – and all plan
plug-in hybrids. Those kinds of cars need good batteries.
Soon lithium ion batteries will replace what’s being used now. But, it’ll still only get
you 40 miles at best in plug ins before it runs out of juice and needs the gas-powered
engine onboard.
So making even better batteries is important to GM, Chrysler and Ford’s Executive
Chairman Bill Ford.
“I actually think the battery break-throughs will now start coming relatively quickly.”
But what if gasoline prices stay low? Will the majority of car buyers care about fuel
efficiency?
GM’s Rick Wagoner bets as the economy improves, gas prices will go back up.
“In general we’d expect oil prices to resume an increase. Hopefully a more gradual
one than we saw last year.”
And the automakers hope the government continues to encourage sales of fuel
efficient cars with tax credits.
For The Environment Report, this is Lester Graham.
A lot of people who drive gas-electric hybrid cars love how quiet they are. But others say hybrids are so quiet they’re hazardous. People in the blind community say they can’t hear hybrid cars coming… and they’d like to have sound added back into the cars. Rebecca Williams has the story:

A lot of people who drive gas-electric hybrid cars love how quiet they are. But others say hybrids are so quiet they’re hazardous. People in the blind community say they can’t hear hybrid cars coming… and they’d like to have sound added back into the cars. Rebecca Williams has the story:
(tap tap tap of white cane)
Fred Wurtzel has excellent hearing but he can’t see.
He can tell by the echo from his white cane when he’s gotten to the edge of a building or the corner of a city block. And he knows cars by their engines.
(sound of car rumbling past)
“That car has a tweety bird under its hood, a loose belt or whatever it was. Now, there was a car going the other direction. (sound of truck going past) That’s probably a UPS truck.”
But he can’t hear hybrid cars – at least not until they’re right at his feet. That’s because the electric motor is very quiet. And when a hybrid comes to a stop, the engine shuts off.
“If you don’t know there’s a hybrid car there waiting, it may start turning and you may step into its path and not even be aware that there’s a car coming around.”
Wurtzel is president of the Michigan chapter of the National Federation of the Blind. He says the blind community wants some sound added back into hybrid vehicles.
“’Course I grew up in the 60’s so a nice Mustang or something like that would be good (laughs)… just a sound that would let me know that the car’s accelerating or the car’s decelerating – whatever a normal vehicle would sound like.”
Well that’s one idea.
Patrick Nyeste has several ideas. He’s a researcher at North Carolina State University. He tried out 18 different sounds on his test subjects.
Everything from sirens (sound of siren)… to whistles (sound of whistle) … to engine sounds (sound of engine).
“I had a horn from a Beetle – so it’s, ‘meep meep,’ and I would just get giggles from that.”
But, he says to make a quiet car safer, the sound needs to be continuous – like a traditional car. That means some sounds can get annoying really fast.
(sound of continuous beeping)
Yeah that’s enough of that.
Nyeste says that engine noise we heard earlier was one of people’s favorites. They also liked white noise (sound of white noise), and the hum sound (sound of humming). He says that’s because we’re used to hearing those kinds of sounds when a car goes by.
He says a sound added to a hybrid also has to be loud enough to be heard above lawn mowers and garbage trucks.
“You want to make sure that the noise is heard, especially by the blind around corners, around objects, I mean some of these sounds can get masked and that’s important information to know where an object or a vehicle is.”
But some people are worried about adding sound to our cities and suburbs, they say they’re already so noisy.
Lotus Engineering says it has a solution for that. They added a four cylinder engine sound to a Toyota Prius. But the volume’s adjustable.
Colin Peachey is an engineer with Lotus.
“You could set the sound to be higher in certain circumstances or quieter in other circumstances. We could actually make the sound to be whatever level we fancied.”
And you don’t have to hear the sound inside the car.
There’s also a startup company in California – Enhanced Vehicle Acoustics. It’s designing a similar system for hybrids.
But it’s not clear how soon quiet cars might start making noise.
Spokespeople for Toyota and the Big Three say their companies are working on solutions. And some states and members of Congress have been talking about requiring hybrids to make some minimum level of sound.
Then, automakers will have to figure out exactly what a hybrid sounds like.

One of the great hopes for a green
car is the plug-in hybrid. It’s like a regular
gas-electric hybrid, only you can plug in at
night. That charge is supposed to let most
people make a typical commute without the gas engine. Carmakers and the government are throwing a lot of money at the technology – GM and Chrysler both hope to release models in the next few years. But the cars might not deliver what boosters promise. In the first part of our series on saving gas, Gabriel Spitzer

One of the great hopes for a green
car is the plug-in hybrid. It’s like a regular

what boosters promise. In the first part of
our series on saving gas, Gabriel Spitzer
reports on what new research says about plug-in
hybrids in the real world:
Ted Bohn is a researcher at Argonne National Laboratory in the Chicago
suburbs and he’s showing off his ride.
“So this a prototype, plug-in hybrid vehicle. The rear half is a 10
kilowatt-hour battery.”
It’s a modified Saturn Vue, with a big old lithium-ion battery in the rear.
That battery is like what runs your iPod – only it weighs as much as a
linebacker.
Ted Bohn: “If you actually had to drive less than 40 miles on a typical
day, you could drive the whole day without starting the engine.”
Gabriel Spitzer: “Could you drive this very vehicle 40 miles round-trip
without starting the engine?”
Ted Bohn: “Close. If you drive slowly. To be honest, 25 to 30 is what
you’ll really do – driving on a nice day downhill with a tailwind is 40,
more realistically, 25 to 30.”
The thing is, you don’t hear those little caveats from some people, like, say,
General Motors.
“You plug it in. And they expect you’ll get up to 40 miles without a drop
of gas. Wow. The Chevy Volt. I’ve heard the future, and it hums.”
That 40-mile range is based on EPA tests.
Argonne scientist Aymeric Rousseau, with backing from the government,
compared those measures to how people drive in the real world.
Based on more than 100 drivers in Kansas City, he found that 40 mile range
shrinks to about 30.
Flip on your AC, and it’s more like 20.
“People now think about, you know, your mileage may vary. Now we
have to think about, your electrical distance may vary, depending on
how you drive, and what accessories you’re using.”
Rousseau says factors like aggressive driving sap the all-electric range.
And don’t forget – we’re talking Kansas City, here.
“When we talk to people from the EPA they actually say that people in
California drive more aggressively than people in Kansas City.”
General Motors concedes the point.
Rob Peterson is a spokesman for GM.
He says driver behavior can have some affect on the all-electric range.
Though …
“I wouldn’t go as low as 28 to 32.”
He says for a reasonable driver, the Volt can still get about 40.
And how about those pedal-to-the-metal Californians? Well, he says GM
studied exactly those people.
“For 64% of the people that we tested, they would be able to finish their
day with a petroleum-free and a tailpipe-emission-free commute.”
That’s not exactly what Argonne found.
Granted, the batteries they looked at were a little smaller than the Volt’s.
Size matters when it comes to batteries.
Said Al-Hallaj teaches at the Illinois Institute of Technology.
He says carmakers could build a battery that would boost up the all-electric
range – the problem is money.
“If you’re talking about a 25% increase, you know, from 30 to 40 miles,
that could mean thousands of dollars. So that could take it out of the
price range that will make it actually practical for the industry to make
it.”
Al-Hallaj says as the technology improves, so will drivers.
People are already getting better at squeezing fuel efficiency out of their
cars.
“For the first time I see people even worried about closing the window
versus opening the window because of drag. And we’re talking about
common people here, just trying to pay attention to, if your tires are not
properly inflated, the you have prob — so people start adapt and
probably get the best out of your battery.”
So it’s not that a plug-in hybrid can’t get 40, it’s just that you need to drive
like a grandmother to do it.
But if gas prices continue to climb, we may be seeing a lot more grannies
behind the wheel.

Some people dream of making things with their hands while they spend their days at the office shuffling papers. Others know from early on that they’re supposed to create with their hands. The Great Lakes Radio Consortium’s Lester Graham profiles a man who knew his art would be of wood and water:
(ambient sound)
At just about any large of expanse of water, you’re likely to find a boat owner who’s found an old wooden powerboat and restored it. The gleaming mahogany or cedar deck is so shiny it looks like plastic.
Here at the Antique Boat Museum in Clayton, New York, thousands of people visit every year, but especially when the antique boat owners gather to show off their craft. John MacLean is the Executive Director of the museum.
“These antique boats are extraordinary pieces of furniture. People would pay a fortune to have this kind of craftsmanship in their furniture in their houses. They have to be fabricated so well and the craftsmanship has to be so good because they have to be watertight.”
The wood powerboats were built from the beginning of the 20th century into the 1940’s. But there are a few wood boats that are not nearly that old. A handful of people are still building the boats. Some are replicas of old designs and some are new designs that look like they might have been built 75 years ago.
Everette Smith is among the contemporary boat builders. He started building boats in 1971… when almost no one was building them. He remembers thinking every step in the process seemed to be a major accomplishment.
“I had finished putting my first plank on. I was so proud of it. I pulled the clamps off and I stood back. And it just went ‘pshhkt’ – it sprung off in a bunch of fragments. So, by the time you really get done with it, you know you’ve accomplished something. It’s a pretty remarkable thing. I think the moment, though, is the moment you first get in it on the water. I mean that is a magic moment.”
Well, that kind of seems like an invitation.
(sound of boat starting up)
I asked if we could take one of his new, but old-looking boats – a long racing boat – out on the water.
“We’re in the Saint Lawrence River in the middle of the Thousand Islands just off Clayton, New York. We’re in a reproduction of a 1910 Lierre number boat designed by Charles Mauer. There were originally twenty of them built, so this is number twenty-one. Top speed’s about thirty-five. You know, it’s a smooth ride, but it’s not fast.”
Fast enough. Water splashes the skipper and passenger every time the racing boat hits a wave. Smith jokes about how the original boats quickly added some windshields. Not this one.
Smith says, as a kid, he was inspired by a great uncle who used to carve canoe paddles for the kids in the family. His grandfather and father taught them to maintain and varnish the wood boats that they had then, and his father used to buy boat kits for Smith and his brother to build.
“I am sort of aware of how the older generation might be looking down and thinking about what we’re doing, and there are times I’m really happy because I know that my Great-Uncle George and my grandfather would love the canoe stuff and the small boat stuff. I think they would really dig that.” (laughs)
And Smith’s contemporaries also dig it. Rebecca Hopfinger is curator of special events at the Antique Boat Museum. She says wood boat builders are admired for their craftsmanship, and their determination to pursue their art.
“Well, I think some of the people wish they were Everette. You know, I’ve heard so many guys come through the front doors of the museum and say, ‘Oh, when I have some more time, I’m just going to work in my shop and try and build a boat.’ And, you know, Everette lives it, breathes it every day. So, there’s maybe a little bit of jealousy in a sense, but there certainly is a desire to the work like Everette does.”
Everette Smith says building wood boats just came naturally in a way that a lot of people who came of age in the 1960’s embraced. Smith says he recently read Bob Dylan’s autobiography and it stirred some of the old feelings that lead him to his career.
“And I realized, reading his autobiography, that the wooden boat thing for me was just sort of a natural progression from that time. It was interest in something that was wholesome and demanding and interesting and useful, you know. And it all seems to fall right in place. It was ‘Of course.’ I didn’t have to think it over, ‘Well, am I going to do this?’ It was just like, this is obvious. This is what I want to do. This is what I got to do.”
And apparently, he’ll keep doing it. Because in his shop: nautical hardware, long boards of hardwood, and parts of salvaged antique boat motors – all seem to promise that Everette Smith will be putting a lot more gleaming wood boats on the water.

A recent study indicates expectant mothers who are exposed to
air pollution see damage to the genetic make up of their newborns.
That might increase the babies’ risk of contracting cancer later in
life. The Great Lakes Radio Consortium’s Lester Graham reports:
The expectant mothers were asked to carry air monitors in backpacks to see how much they were exposed to air pollutants. The Columbia University researchers chose 60 mothers in low-income neighborhoods. Dr. Frederica Perera is chief author of the study.
“All of our mothers in the study were non-smokers. So, the primary source of these pollutants in air would be things like motor vehicles, emissions from residential heating units, burning fossil fuel and also from power plants located even fairly far away.”
It’s the fist study to make a connection between air pollutants causing genetic changes in the womb that could increase cancer risk. Earlier studies by the researchers already revealed greater prenatal exposure to air pollution caused lower birth weights and smaller heads in newborns.
