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.

Hybrid Car Ownership Drives People Together

Some hybrid car owners are starting clubs to socialize and to learn how to squeeze even more miles per gallon out of their fuel-efficient vehicles. The number of hybrid owners is still small enough that the owners feel a little “special.” The GLRC’s Chuck Quirmbach reports:

Some hybrid car owners are starting clubs to socialize and to learn
how to squeeze even more miles per gallon out of their fuel-efficient
vehicles. The number of hybrid owners is still small enough that the
owners feel a little “special.” The GLRC’s Chuck Quirmbach reports:


Bradley Fons says he already thought about the environment a lot before he
purchased a used hybrid car three years ago. He bought a Honda Insight:


“…And I kind of figured out how to drive it to get the best mileage but there
was no support, no help out there at that point to assist me.”


Eventually, Fons found a group of hybrid owners who helped him answer
some questions about the car.


(Sound of group meeting)


But this year, with some help from his family, Fons has done one better: he’s
organized a hybrid owners club.


(Marie Fons) “…And put your name on one of these little things, for a door prize. I know, work, work, work, work, work. Here, you guys want to work on the
door prize thing?”


Bradley Fons’ wife, Marie, is helping about two dozen people check in. This
is the first meeting of the hybrid owners group. They get to know each
other by their name, their city, and the kind of hybrid they drive:


“I’m Kathy Moody from Racine and I have a ’05 Prius.”


“I’m Bill Vaness from Waukesha and I ride in my wife’s ’03 Prius (laughs).”


(Group member) “At least you’re honest.”


“My name is Sherrie Schneider, I’m from Bristol and I have an ’06 Civic. Picked it up about a month ago and I’m here to learn a lot ’cause I don’t know how to get the mileage you all
are getting but I’m going to learn (laughs).”


And so Bradley and Marie Fons go into teaching mode, offering encouragement and advice about how to get the most miles per gallon from the cars. The hybrid of gas engine and electric batteries usually cost more to buy more than similarly sized conventional cars. So the new owners are anxious about getting the best mileage possible.


Bradley Fons preaches patience. He says for new vehicles, owners have to work through
the car’s several thousand mile break-in period before they get the kind of gas
efficiency the cars can reach:


“So if you’re getting in the forties, ya know, high 40, mid 40, to low 50s in
a Prius and it’s new, don’t worry about it, ya know. It’ll come.”


Fons says some of these cars will get miles-per-gallon in the 60s and 70s. Then there are
the controversial people who’ve become what’s known as “hyper-milers,” getting 80 or 90
miles per gallon through various means that even the hyper-milers concede aren’t
completely safe.


Fons introduces Wayne Gerdes, who tells how to steer a hybrid
in the air draft right behind 18-wheel trucks:


“Hopefully you’ll understand that this close in, is this one car to one and a half second
back, that’s a dangerous area. I don’t recommend anybody doing it, but you’re gonna find
your fuel economy going through the roof on that.”


The hybrid owners club that the Fons family has organized also takes club
members out in hybrids for some lessons on the road:


“So we’ll go down, ya know, another set of streets.”


Bradley Fons sits in the front passenger seat of a Toyota hybrid. He’s
teaching a club member named Bill a driving method called the “pulse-and-
glide.” Basically, it involves only occasionally tapping the gas pedal and coasting
a lot, so that neither the car’s motor or electric battery system is operating much.


When pulse-and-glide is done right, a monitor on the dashboard reports a surge in
fuel efficiency. After some difficulty, Fons helps Bill get the hang of it:


“All right, foot totally off. Now just on a little, there you are. You’re in it, hold it,


(Bill) “Do you take your foot off when you’re in there, though?”


“No, you have to leave pressure on it. Boy, that was the longest glide you did (laughs)!”


It’s moments like these that make Bradley Fons glad he and his family are helping to
spread the hybrid car message. But Fons sees an opportunity for members of his club to
go outside the group and become pro-hybrid activists:


“Hoping dealers get more hybrid cars, working for candidates that push alternative fuels,
sustainable energy, anything that can be done…because at this point in time it hasn’t been
coming from the government. They’ve done some, but our group doesn’t feel they’ve done
enough.”


Fons says politicians should listen to hybrid owners and hybrid clubs, because they’re
offering part of the solution to America’s oil addiction.

Migration Season Brings Bird Flu Worries

Researchers have been monitoring the spread of a potentially deadly
strain of avian influenza overseas. Health officials worry the H5N1
strain could mutate into a form that could infect humans. Some
researchers say the virus could make its way to the United States as early
as this fall… by way of wild migratory birds. The GLRC’s Christina
Shockley reports:


Wild birds carry all sorts of influenza viruses. Most are of no threat to
people, but the H5N1 strain is different. When it gets into people… it’s
often fatal. Overseas the strain has killed whole farms of poultry such as
chicken and ducks… it’s also infected other types of animals, including
cats.


The H5N1 strain has not been found in the United States, but most
experts say it’s just a matter of time before it is. Some say infected
domestic poultry or smuggled pet birds will likely bring the virus to the
U.S. Others say the virus could come here by way of migrating birds…
that are on the move now.


Steve Schmitt is the lead veterinarian for Michigan’s Department of
Natural Resources. He says birds from Asia… that are possibly infected
with the H5N1 strain are on their way to Alaska right now. There, they
could mingle with birds that will later fly back to the United States.
Schmitt says there are four major flyways over the U.S.… the Pacific,
central, Mississippi, and Atlantic.


“There are birds that will winter in Asia and then come back and nest in
Alaska. If they bring the virus back with them, then they could transmit
that to birds that are in Alaska that come down any of these four major
flyways, and that of course is a big concern, moving it all over the
country.”


Schmitt says most birds that nest in Alaska use the Pacific flyway along
the Pacific coast… to migrate south to the U.S. and Mexico. He says
that means, if the virus were to come to the United States via migratory
birds, the pacific coast would probably be its first stop in the lower 48.
Schmitt says then, birds that use the other flyways could become
infected.


“Most of the migration is north-south, but you do have a few that will
move – jump over to another flyway, and when that happens, the
potential to move the virus to that new flyway happens. Once it’s in a
new flyway, that north-south movement would take over.”


Programs are underway an Alaska and throughout the United States to
test wild birds for various strains of avian influenza, including H5N1.
Experts say waterfowl and shore birds are the most likely carriers of the
dangerous strain, but some say land birds – such as migrating songbirds –
should be tested, too.


(Sound of birds)


Julie Craves studies land birds at the Rouge River Bird Observatory on
the University of Michigan’s Dearborn campus. She catches and bands
thousands of wild birds each year during their spring and fall migrations.


This year, Craves will participate in a study that hopes to eventually test
hundreds of thousands of birds across the U.S. and Latin America for
avian flu strains.


“It’s just a great opportunity with people handling birds already, we may
find out some very interesting things about which subtypes are present in
land birds, and if indeed this disease does come to North America, we
will have a head start on seeing what types of migratory pathways are
being used by birds.”


Craves says very little is known about how avian flu moves among land
birds, and experts say each time the virus is transmitted to a different
species it mutates, and each time it mutates, the chances are greater that
it will change into a form that’s easily passed among humans. That’s a
big concern, because such a mutation could lead to a quick spread of
human cases across the globe.


But some say that might never occur… they say the strain might be
unable to mutate into one that’s dangerous to humans.


Arnold Monto is a professor of epidemiology at the University of
Michigan. He says there will be a problem if the strain mutates, but it’s
unlikely people will get the virus from migrating birds.


“I doubt very much whether we’re even gong to see even a handful of
cases in the United States, should avian influenza arrive, and it probably
will, with the migratory birds coming down from Alaska, perhaps next
fall.”


Monto says most of the human transmissions overseas have been from
poultry being raised in the back yard, and not from wild birds. That
means visiting the ducks and geese in the park… and feeding songbirds
in the back yard… are not high-risk activities. Monto says people should
take basic precautions, such as washing hands, to avoid contracting any
sort of flu virus.


Many experts say, on the list of things to worry about, catching a deadly
form of avian influenza is no where near the top of the list of dangers.

Winter Cyclists Woo New Recruits

There are some people so determined to fight pollution and traffic
congestion that they bike instead. There are even some brave souls who
bike year-round, come good weather or bad. The Great Lakes Radio
Consortium’s Shawn Allee meets one woman who wants to join them:


For a lot of people, transportation’s more than just a way of getting from
point A to point B. They take it personally. They want to cut air
pollution, use less energy, or they want to save money on commuting.


For those kinds of reasons Julie Lenfest doesn’t own a car. For years, she
relied on buses, but she hated them. They ran late. They didn’t go
everywhere. She was fed up, so she tried biking.


“I hate to beat down on the buses, but I got really frustrated with the
buses and it made me want a car, and then having a bike made me not want a car
anymore … it took that whole frustration away.”


For a while, each ride was a kind of … personal triumph.


That was fine while she lived in California, but Julie’s routine hit a snag
after she moved to Chicago. She was used to mild, Californian winters,
not blustery, frigid Midwestern winters. Sometimes the cold here gets so
bad it brings tears to your eyes. No wonder Julie chickened out last
winter. She stayed off her bike and hopped the bus instead.


“I don’t know, just, ah, talked myself out of it, but we’ll see. Now, I need
adventure.”


Julie started thinking about winter biking weeks before there was any
snow. She needed advice. So, she came to a seminar on how to prep
herself and her bike for winter. She’s come to the right place.


“I’m Alex Wilson. This is my shop, West Town Bikes … (continue)”


If anyone’s capable of teaching Julie and the other folks here, Alex is.
He’s more than just a winter biker and expert repairman. He’s a bike
evangelist.


“I just can’t find any inherent bad in bikes. Plus, bikes are fun, you know.
What better reason to be interested in bikes than, bikes are a lot of fun?”


Alex starts the class with how to keep warm. The trick’s not to get too
warm, otherwise you get drenched in sweat. Layering’s good, but
there’re no hard and fast rules about which long underwear goes with
what rain gear. Alex says trial-and-error works best.


Then there’s safety. Alex suggests putting reflective tape on your bike as
well as your jacket.


“Motorists are not looking for cyclists in the winter, so you need to be
seen.”


The next lesson’s about street salt. Salt corrodes your bike and can make
it hard to peddle.


“After after you’ve gotten to your destination, do this:”


(Sound of a bang)


“Bounce your bike hard and knock off all the stuff that’s built up on your
bike.”


Alex says all this mechanical advice is important but misses the point.


“The biggest thing that holds people back from biking in the winter is not
any gear or special equipment. It’s having the will to do it or having the
courage to do it.”


And there’re plenty of things to be scared of. Everything from being seen
in geeky winter outfits to more serious stuff, such as frostbite, but Julie’s
encouraged and she peddles out of the seminar, with her resolve intact.


(Sound of bike wheel)


A month later, I meet Julie to see whether her determination was a match
for the weather. Today, she’s biked to an outdoor ice rink. Snow’s
heaped along the sidewalks and we can see our breath. While she laces
her skates, she tells me the good news first. Turns out, she hasn’t been
alone.


“There are other people winter biking, I thought I’d be the only person.”


These strangers offered useful tips on clothes and safe routes.


There have been problems, though. Early on, Julie was looking for
adventure, but she changed her tune after the season’s first major storm.


“There was snow and it was slippery and they hadn’t put salt down yet.
So I decided I would walk on the sidewalk because I didn’t trust my
brakes and I didn’t trust other people’s brakes.”


That day sapped the fun out of winter biking, but she realized something
else. She’s kind of over the thrill. She’ll keep biking, but more and more,
it’s just the way she gets around. She doesn’t have to prove anything to
her friends.


“They just don’t understand how you can live without having a car, and
I’m just tired of explaining it to them over and over. So, I just say I can be
there at this time and I don’t tell them how I’m getting there; it’s my
business.”


So, she doesn’t talk about it so much anymore. It’s good to cut down on traffic or
save energy, but winter biking’s not so easy. If she chooses to keep it at, it’ll
be because she enjoys it, not because someone’s convinced her she has to. That’s
to say, it’s personal, and, to her, important.

Group Releases Cosmetics Safety Database

Anyone who slathers on lotions, deodorants, and shampoos can now search an online database to find out how safe those products are for their health. The Great Lakes Radio Consortium’s Sarah Hulett reports:

Anyone who slathers on lotions, deodorants, and shampoos can now search an online
database to find out how safe those products are for their health. The Great Lakes Radio
Consortium’s Sarah Hulett reports:


The Environmental Working Group looked at the ingredients of more than 14,000
products, and it rated the safety of those products by matching their ingredients with
government listings of toxic chemicals. Consumers can search the database by product
type or by brand name.


Jane Houlihan is vice president for science at the Environmental Working Group. She
says the database is important because federal regulators in the U.S. leave safety testing
up to the cosmetics industry.


“What we have right now is a system where individual companies have the ability to
decide what’s safe enough to sell. We don’t have a national safety standard for cosmetics.
So safety really varies widely.”


Some of the products that have raised health concerns include dark hair dyes – which
some scientists have linked to bladder cancer, and there are concerns that chemicals used
in nail polishes could cause birth defects in baby boys.
