This week, the North American International Auto Show in Detroit opens to the public.
Every year, the event is a showcase for the newest trends for tomorrow’s cars and trucks,
and this year, the big trend is fuel-efficient vehicles. Cleaner cars have been promised
before, but Dustin Dwyer reports that this year’s green car concepts could be more than
just an attempt to polish up a dirty image for the auto industry:


The press previews for this year’s Detroit auto show were made up of three straight days
of back-to-back new product launches. Dozens of new vehicles were unveiled. Hundreds
of glossy brochures were offered to reporters, and nothing generated as much interest as
the new Chevrolet Volt concept vehicle:


(Sound of buzzing)


A packed crowd gathered for the flashy and noisy unveiling. GM executives announced
that the concept car could run up to 40 miles without using a single drop of fuel. It runs
instead on electricity cranked out by its next-generation lithium-ion batteries. When the
liquid fuel system eventually does kick in, it recharges the battery for better fuel
economy, getting up to 150 miles per gallon.


And as GM CEO Rick Wagoner told the audience, the Chevy Volt represents a new way
of thinking for the world’s largest automaker. It comes from a realization that oil alone is
highly unlikely to supply enough energy for all of tomorrow’s vehicles:


“For the global auto industry, this means that we must as a business necessity, develop
alternative sources of propulsion based on alternative sources of energy in order to meet the
world’s growing demand for our products.”


GM wasn’t the only automaker to unveil a fuel conscious vehicle at this year’s auto show.
Ford’s Airstream concept, and Toyota’s FT-HS sports car concept both featured hybrid
style powertrain systems, backed by a lithium-ion battery.


It might not be all that surprising for automakers to release such vehicles after a year in
which gas prices surged beyond three dollars a gallon, but analyst Jim Hall of Auto
Pacific says gas prices aren’t the reason for automakers to get into low or no emission
vehicles.


“You do it for two reasons, one, the potential of getting out of the business of making a
mechanical engine that has to be machined and made of multiple pieces and assembled,
and the other part of it is, you never have to spend another penny on emissions controls,
and emissions research, and emissions development and emissions engineering, which, at
every major car company is billions of dollars.”


So, basically, greener technology will eventually be cheaper technology. That means that
for perhaps the first time in the history of the auto industry, the interests of
environmentalists and the interest of business-minded bean counters are finally in line.


The big question now is how to get to that greener future. The concepts at this year’s
Detroit auto show all point to lithium-ion batteries as the next frontier. These batteries
are more powerful, and potentially cheaper than the batteries in today’s hybrids, but
they’re also less stable, and don’t last as long.


GM executives say they think they can resolve those issues and have a lithium-ion
powered vehicle by the end of the decade, but Jim Hall says no way:


“I worked on an electric vehicle program when I was employed in the auto industry
directly, and I learned that there are three kinds of liars in the world. There are liars,
damn liars and battery engineers.”


Of course, not everyone agrees with Hall’s assessment. Some lithium-ion proponents
even argue that the technology could be ready to go right now. Ford, General Motors and
the Chrysler Group have asked the federal government for more funding to speed-
development of lithium-ion batteries.


They say the Japanese government is giving its car companies several hundred million
dollars for battery development, and they want a comparable effort from the US
government. But even if Detroit automakers don’t get the money, almost everyone agrees
that big changes are coming for the auto industry, and that decades-long battle between
the good of the environment and the good of carmakers could be coming to a close.

Limited Green Choices From Automakers

The annual season of major U.S. auto shows is underway. And this year, the

The annual season of major U.S. auto shows is underway. And this year, the hot trend
isn’t about horsepower or towing capacity. It’s about saving you gas at the pump.
But, as
Dustin Dwyer reports, the rhetoric is still ahead of the reality:


At the Los Angeles Auto Show, some promises were made by auto companies about
building cleaner, more fuel-efficient cars.


The problem is that, so far, the big gains have only been in a few specialized
vehicles, not
across the board.


David Friedman of the Union of Concerned Scientists says auto companies are making
some progress on cleaner technology. But he says the real test is whether they can
improve efficiency across all types of vehicles.


“Right now if you’re a mother of three and you need to have all those three kids in
car
seats, you probably need a minivan. A compact car won’t work for you. And yet, if you
walk into the showroom today, your choice for a minivan is what 20, 21, maybe 23 miles
per gallon? That’s no real choice.”


The next chance for the automakers to unveil new gas conscious vehicles comes later
this
month at the Detroit Auto Show.

More Room on the Road for Plug in Cars

A new study says there’s enough power being generated in the United States
to run a lot more plug-in electric vehicles. Dustin Dwyer reports the
environmental benefits of such a switch are harder to pin down:

Transcript

A new study says there’s enough power being generated in the United States to run a
lot
more plug-in electric vehicles. Dustin Dwyer reports the environmental benefits of
such
a switch are harder to pin down:


The study from the U.S. Department of Energy finds that up to 84 percent of the
vehicles
on the road could be powered by today’s electric plants, if plug-in vehicles became
more
available.


But in areas dominated by coal-burning plants, electric cars would just switch one
kind
of pollution for another.


Lead author Michael Kintner-Meyer says the future power grid is likely to be cleaner
than today’s. And he says there’s also a benefit from reducing consumption of foreign
oil.


“Although there was a very conservative, I think a very conservative estimate,
overall, I
think the story of plug-in hybrids is a very good one.”


General Motors has said it’s developing a plug-in gas/electric hybrid vehicle. But
executives have not said when that vehicle will be on the road.

Mpg Window Stickers to Change in 2008

There’s going to be a change to the sticker that tells you the estimated gas mileage on a new vehicle. Dustin Dwyer reports that the US Environmental Protection Agency is rolling out the change in an effort to make the estimates more accurate:

Transcript

There’s going to be a change to the sticker that tells you the estimated gas mileage on a new vehicle. Dustin Dwyer reports that the US Environmental Protection Agency is rolling out the change in an effort to make the estimates more accurate:


The US EPA has used the same standard to test for gas mileage since 1984.


Bill Warem is with the Agency. He says the tests were only done at room temperature, they didn’t include using the air conditioner, and they didn’t include fast accelerations.


Warem says that hardly reflects real world driving conditions.


“Our concern with the methods that were previously used is they were not as accurate as they could be in estimating typical mileage that a consumer would expect to get from a new car that you purchase.”


Warem says the new way of testing for mileage will show up on stickers for 2008 vehicles.


He says the estimated miles-per-gallon for the average car is expected to drop by about 12%.

The company accused of “killing the electric car” says it’s going to bring a new version of plug-in car back to the market. General Motors recently unveiled plans for a new hybrid SUV. They claim the new technology will get double the gas mileage of any current SUV. But as Dustin Dwyer reports, the CEO of GM says he’s not sure when the vehicle will be on the roads:


GM CEO Rick Wagoner announced the hybrid project at the Los Angeles Auto Show. He said the vehicle would have the ability to be plugged into a wall, to use more electricity and less gas.


The announcement was part of a major speech on GM’s commitment to alternative technologies.


And, although Wagoner set no dates for when his company would have these technologies, Bradley Berman of hybridcars.com says the speech was a big first step.


“For so long, we didn’t even hear the right talk. How can you walk the right walk if you’re not even talking the right talk? At least now it’s the right message. It’s the right way of looking at it. And that sounds promising.”


Berman says GM still has a long way to go to catch up with rival Toyota on hybrid technology.

The 100 Mile Meal: A Homegrown Thanksgiving

Thanksgiving is about family, friends, and ridiculous amounts of food.

Thanksgiving is about family, friends, and ridiculous amounts of food. But the food we buy can have a big impact on the environment. And a lot more people are starting to look for local ingredients to put in their meals. One movement encourages people to get all their food from within 100 miles of their home. Dustin Dwyer tried to find out how practical that could be for his Thanksgiving feast:


I like to look at labels on my food. I don’t care so much about the nutritional info, I just want to know where it came from.

But there’s a problem with that. Even if I know where something is packaged, I still have no idea where the actual ingredients come from. I mean, where the heck do they make partially hydrogenated soybean oil?

I have no idea. And so, for one meal, for the most important meal of the year, I decided to try to get all my food, and all the ingredients in my food, from within 100 miles of my apartment in Southeast Michigan.

If you’re impressed by my ingenious and creative idea, don’t be. I stole it from someone else. Alisa Smith and her partner James MacKinnon were on a 100 mile diet for a year, and they’re writing a book about it. I called up Alisa for some help.

Dwyer: “So my wife and I are going to do the 100 mile Thanksgiving, and I want to ask some advice.”


Smith: “Oh, great! For doing a single meal you picked a very good time to do it because it’s the harvest bounty, so that makes life a lot easier.”


I’m thinking, excellent, this could be a piece of cake. But I’m worried about a few tough ingredients, such as salt. Alisa says salt is a problem for a lot of people.


“I think in the end, you probably will find that salt isn’t available. And not being able t o make it yourself you might just say ‘okay salt is going to be an exception for us.'”


Ok, fine, but I still wanted to make as few exceptions as possible. I’ve got to have a challenge here, somehow.


That said, our menu would be simple: just turkey, mashed potatoes, stuffing and pumpkin pie. Turkey turned out to be easy.


“Roperti’s Turkey Farm.”


Christine Roperti has been living on her family’s turkey farm in suburban Detroit all her life. Farms like this one are getting crowded out more and more by suburban sprawl. There’s even a brand new subdivision next door to Christine’s place. There have been offers for her land too.


“Yeah, but I don’t want to go anywhere. I like the farm, and like raising my turkeys.”


I liked knowing that Christine actually enjoys this, and cares about it. It made me feel good. And that’s important, because I was also paying a lot more for her turkey than the store-bought stuff.


Anyway, I was flying high, and things were going really well. My list of exceptions was firming up, and it was mostly spices: salt plus all the spices for the pumpkin pie.


Then, while I was bragging at work about how I’d be able to get almost everything but salt for my local dinner, someone reminded me that there are actually salt mines under the city of Detroit.


Like a good journalist I looked into it, and ended up on the most absurd shopping trip of my life.


“Okay I’m headed over the Ambassador Bridge, going from Detroit to Windsor, Ontario. They do have salt mines in Detroit, but they don’t sell that salt as food salt in the US, they only sell road salt. So in order to get food salt that’s made within a hundred miles of my house, I have to go to Canada.”


Because of some trade regulation I don’t understand, table salt from this mine can’t be commercially shipped into the US. So I ended up in a city I barely know, looking for a grocery store. I went into the first, and then the second without finding the right brand of salt. Then an hour or so later, in the third store…


“Finally! Windsor salt.”


So, I wasted a lot of fuel putting this dinner together. It’s probably still an improvement over what the Sierra Club says is an average two thousand miles of driving that goes into each ingredient for my usual dinner.


But here’s the thing: if all this local stuff is available, I think I should be able to get it at the grocery store down the street. I should probably let them know that, and let them know I’m willing to pay more for it. I mean, that’s better than driving to Canada for salt, anyway.


But making that happen would take a lot more effort, a lot more voting with my pocketbook, and a lot more than just checking labels.

Taxpayers Subsidizing Record Ethanol Profits

The nation’s leading food processor is making big profits from ethanol. Archer Daniels Midland has had two straight years of record profits. And in its latest quarter, the company nearly set another record. Dustin Dwyer has more:


ADM’s profits on corn processing, which includes ethanol production, more than doubled in its latest quarter. Total profits for the period were about $400 million.


Daniel Kammen studies energy policy at the University of California – Berkeley. He says while ADM is making lots of money from corn-based ethanol, future profits could go to companies that make ethanol from switchgrass and other woody products.


“It’s really the first companies that switch into cellulosic sources that I think are going to be the big winners, because they’re going to capture the environmental prize as well as the offsetting gasoline prize.”


ADM executives have laid out a new strategy that includes plans to expand ethanol production from fuel sources other than corn.


Daniel Kammen notes that there might not even be a market for ethanol if not for government subsidies, which also helped ADM reap its bigger profits.

Great Lakes Fish “Quarantined” by Usda

Regulators are worried about a fish disease found in the lakes that could spread to other areas. Federal officials are trying to figure out the next step after banning certain shipments of fish in the Great Lakes Region. Dustin Dwyer has more:


The disease is called viral hemorrhagic septicemia. It can cause fish to bleed internally and die.


The disease is harmless to humans, but federal regulators say it could lead to massive die-offs for up to 37 different species of fish, so they’ve stopped fisheries in the eight Great Lakes states, and two Canadian provinces from shipping those species over state lines. The ban only affects live fish.


Jim Rogers is a spokesman with the US Department of Agriculture. He says the ban is meant to stop the spread of the disease while officials figure out what to do next.


“Now eventually that federal ban is going to lift, and we are going to be allowing movement. But right now we just can’t do it with the threat of this disease hanging over us.”


The fishing industry in the Great Lakes has been valued at more than $4 billion a year.

Part 1: Carmakers Push for More Ethanol

This summer, drivers got a crash course in the dangers of fossil fuel. Gas prices shot above $3 a gallon, concerns about global warming surged, and instability continued to plague areas of the world where oil is produced. We’ll be taking a look at some of the technologies that could help the US kick its fossil fuel habit. We’re starting with an alternative fuel that’s been sprouting up in gas stations across the region. Dustin Dwyer has this look at the promise, and the limitations of ethanol:


This summer, Misty Childs found a way to do something positive about the fossil fuel problem. She says that she and her husband realized their Chevy Silverado pickup could run on E-85, a blend of 85 percent corn-based ethanol and 15 percent gasoline.


E85 burns cleaner than gas alone, so it’s good for the environment. And the ethanol is made from corn grown in the US. As she tops off her tank at a gas station, Childs says that makes a difference.


“It means a lot that we’re doing something for our country here, and not having to rely on others.”


Detroit’s Big Three automakers have been making a big push for E-85 in the last year. E-85-capable vehicles get the automakers a credit on federal fuel economy standards. So, even if drivers put regular gas in the vehicles instead of E-85, Detroit still gets a credit for doing better. And this summer, as more buyers became aware of the problem with fossil fuels, E-85 was just about the only alternative Detroit had to offer.


But ethanol as it’s currently made has limits. Jason Hill is a researcher at the University of Minnesota. He recently published a study on the long term outlook for corn-based ethanol.


“What we found is if you convert every corn kernel we produce in this nation to ethanol, we would be able to offset only about 12 percent of our national gasoline usage. So that’s not that large.”


That’s every corn kernel, including what we currently use for food. Which brings up another problem with ethanol: if E85 jumps in popularity, will that mean less corn for animal feed and grocery stores?


Maybe. Corn originally became popular because it was already being grown around much of the country, with help from federal subsidies. And ethanol processors, such as Archer Daniels Midland, also got tax breaks for making corn-based fuel.


But there’s another option for ethanol. Inside a lab at Michigan State University, researchers are working on the next generation of the fuel. This is what’s called cellulosic ethanol. Instead of using grains like corn kernels, cellulosic ethanol is made from the starches in plant cell walls. It can be made from pretty much anything that stands up straight – wood, prairie grasses and corn stalks.


That offers the possibility to increase the ethanol output for every acre of land devoted to the crops, and those crops don’t require fossil fuel-based fertilizer. They also don’t require planting every year by gas or diesel burning tractors the way corn does.


Professor Bruce Dale heads research into cellulosic ethanol at MSU. He says the current problem with cellulosic ethanol is finding a cheap way to break down the stiff materials. His lab uses ammonia to do the trick.


“The idea is to make cheap sugar. And the plant cell walls potentially could give you the cheapest sugar on the planet, if we could figure out how to get at that sugar easily. That’s what our ammonia process does in combination with the enzymes.”


It turns out that, much like a teenager eating pop-rocks, cars and trucks get a whole lot of energy from fuels based on sugar. Dale says most woody plants have plenty of sugar, but it’s really hard to get that sugar out.


Dale says some cellulosic ethanol could be on the market in the next few years, and the fuel could eventually sell for about 60 cents a gallon.


Right now, ethanol is still hard to find at the pumps. And one study says, even with major investment over the next decade, cellulosic ethanol might only equal half of our current oil useage by 2050.


That’s still a lot. But to really eliminate the need for gas, many experts say it’ll take more than just one technology.

Part 3: Zero Emission Hydrogen Future?

  • Underneath the hood of a hydrogen powered car. (Photo courtesy of US Department of Energy)

You’ve probably heard that the auto industry is looking into hydrogen as a possible fuel for future cars and trucks. Hydrogen offers the potential for cars with close to zero harmful emissions, but those cars won’t be on the roads in big numbers anytime soon. Dustin Dwyer has this look at what’s being done now to get ready for a hydrogen future:

You’ve probably heard that the auto industry is looking into Hydrogen as a possible fuel for future cars and trucks. Hydrogen offers the potential for cars with close to zero harmful emissions, but those cars won’t be on the roads in big numbers anytime soon. Dustin Dwyer has this look at what’s being done now to get ready for a hydrogen future:


To many people, hydrogen-powered cars might sound about as legitimate as flying cars. They both seem like really good ideas. Hydrogen could lead to cars that have basically no harmful emissions. Flying cars are just cool. For flying cars, the technology hasn’t come through. That’s despite all the promises of countless sci-fi movies.


But people in the auto industry insist hydrogen cars are the real deal, and they’re backing it up with real investment money. General Motors, the world’s biggest car company, has spent more than $1 billion already to develop hydrogen fuel cells.


Julie Beamer is GM’s director of fuel cell commercialization. She says things such as biofuels and gas-electric hybrid technology are important in the short term.


“But ultimately, you are back to what is the long-term sustainable solution? We believe very strongly, it is hydrogen and fuel cell technology.”


At GM, hydrogen fuel cells represent a complete reinvention of the automobile. The internal combustion engine, which has powered nearly every car for the past century, is out. And there’s a lot of other high-tech gadgetry in GM’s prototype hydrogen vehicles.


But Hydrogen doesn’t have to be a revolution. You can actually use existing engines.


Jeff Schmidt is an engineer with Ovonic Hydrogen Systems in Michigan. He’s hooking a hydrogen pump up to a modified Toyota Prius.


“You can hear the fuel is pushing through the nozzle, there are orifices and it just whistles as it’s fueling up.”


This is a pump that looks like any other gas pump you see. It has a few extra tubes and wires, but basically it works the same as gas pumps you use all the time. As Schmidt jumps behind the wheel, he says that was the idea with the prototype car, as well.


“The car is very similar to standard Prius in function and drivability. Simply a matter of getting in the car, seat belt, push the power button to start.”


Essentially, Ovonics just pulled out the standard gas tank, and put in a tank that could safely store Hydrogen. That tank is a little bit heavier than a normal gas tank, and you lose some horsepower from an engine that was originally built for gasoline. But Schmidt says for the most part, this hydrogen powered car works the same as your car does. It just uses a cleaner fuel.


And the technology is pretty much ready to go. Schmidt says the car could be mass produced and put on the roads right away. The problem is nobody would know where to fill up.


“That has to be worked out. I mean, we see a gas station on every corner right now.”


Gary Vasilash is editor of Automotive Design and Production magazine. He points out there are already problems with just getting biofuels such as ethanol into gas stations, and he says getting Hydrogen to filling stations will be much worse.


“People are talking about, ‘Well, gee it’s so difficult to get ethanol,’ you know, and ethanol’s from corn, right? Well, where is there free hydrogen? Nowhere.”


The most talked about way of getting hydrogen at least in the short term, is from a process involving fossil fuels, but that process would create heavy CO2 emissions on the production side. So the total measure of pollution from cars, what’s called the well-to-wheel impact, might only be cut in half compared to current levels.


So GM’s Julie Beamer says the ultimate goal is using renewable wind or solar electricity to pull Hydrogen out of water through electrolysis.


“Those sources obviously, while they’re near term not as economically attractive as what natural gas would be, but the renewable-based options do represent to completely eliminate greenhouse gas emissions through the total well-to-wheel basis.”


That could be a big, big improvement for the environment. But no one can really say how long it might take. In the meantime, auto companies and researchers continue to work on the incremental steps, while the rest of us wait for the era of truly clean automobiles to take flight.
