Coal-burning power plants from Great Lakes states are often blamed for much of the pollution that hits the East Coast. But now, the federal government is proposing a massive research project that they say could eventually perfect a way to burn high-sulfur coal without sparking pollution. The Great Lakes Radio Consortium’s Bill Cohen has this report:
The feds are proposing a massive one-billion-dollar plant that’s billed as the world’s first non-polluting, coal-burning power plant. About twenty states say they’ll compete for it. Ohio is one of them. Mark Shanahan of the Ohio Air Quality Development Authority says the plant will first turn coal into gas. And then either recycle or safely store the by-products.
“And when it turns to gas, it’s able to pull out the pollutants much more efficiently and economically. It will pull off hydrogen for fuel cells and it will also test the ability to put carbon dioxide into very deep geology to basically bind it up forever deep in the earth.”
The U.S. Energy Department will pay for most of the plant, but it will be several years before it’s actually online.

Vegetables are less nutritious than they were 50 years ago. That’s the finding of a new study that tested 43 different garden crops. The Great Lakes Radio Consortium’s Chris Lehman reports:
Researchers analyzed U.S. Department of Agriculture nutrition data from the past 50 years. They found that levels of several vitamins and minerals decreased by as much as 38% in garden crops over the time period. Don Davis is the lead author of the study. He’s with the University of Texas Biochemical Institute. He says the decline could be the result of decades of breeding plants to produce more and bigger vegetables.
“There’s emerging evidence that when you genetically select for higher yields, you get a plant that grows bigger and faster but it isn’t necessarily able to produce nutrients or uptake minerals from the soil at the same faster rate.”
Davis says despite the fact that vegetables have fewer nutrients in them, he says they’re still the most efficient way to get vitamins and minerals into your system.

A Toronto researcher says most communities are underestimating a potential source
of cheap electricity – raw sewage. The Great Lakes Radio Consortium’s Karen Kelly reports:
University of Toronto professor David Bagley collected waste water at a North
Toronto water treatment plant. He took the sewage into his lab, dried it and
then burned the solids to see how much energy they produced. He estimates the
energy produced from sewage at three treatment plants could produce more than
100 megawatts of electricity. That could be enough to keep a small town going
for a year. But Bagley says few take advantage of this resource.
“Our measurements show that there’s enough energy that we should be able to
completely offset the electricity needed to run the plant, and have extra
left over the send back to to the grid.”
Bagley finds communities are reluctant to invest in the equipment they’d
need to convert sewage into power. But he’s hoping to to design a cheaper
and more efficient system so more people can get the most out of their sewage.

The loss of traditional manufacturing jobs has hit Great Lakes states hard in recent
years. But some business owners believe they are on the cusp of creating a new type of
manufacturing base. The Great Lakes Radio Consortium’s Julie Grant spent some time in
one community that’s discussing how new businesses can provide a foundation for the
future:
Not long ago, there were lots of good-paying factory jobs in northeast Ohio. But the state
has lost 200,000 manufacturing jobs in the past four years. Some business people and
academics are trying to shape a new economy for the region. Their efforts could be
symbolized by a little bird…
“I need a Sparrow, I need it…”
A sparrow is an electrically charged three-wheel motorcycle that’s fully covered in steel.
It looks like a tear drop… or maybe a gym shoe. David Ackerman isn’t sure if he’d pick
one in bright orange…
“…but look, there it goes, look at it go! Is that the weirdest thing you’ve ever seen? I
love it! It’s like something out of “sleeper.” But it’s very sleek and cool and futuristic…
Does it really go 70? Yeah, it goes 70….”
While Ohio and other Midwestern states might have a tough time competing globally in
the steel market, some economists believe innovative transportation is one way Ohio
could build a foundation for a new economy. The state has put millions of dollars into
fuel cell research, Honda is building hybrid cars in central Ohio, and newer companies
are working to make auto engines cleaner and more efficient.
Some of those business owners gathered with people from the community to discuss how
transportation technology could be part of the region’s future. Bob Chalfant of a
company called Comsense spoke on the panel. He says the technology they’re
developing could have a huge impact…
“…the benefits to Cleveland are jobs. We figure the total market for pressure sensors for
combustion applications is about 2.2 billion dollars.”
Chalfant’s company expects to create 2,000 jobs in Cleveland. But if businesses like
Comsense are going to girder the area’s new economy, they’re going to need educated
employees for their high tech manufacturing jobs. The problem is, many young educated
folks are leaving the Midwest.
Meredith Matthews is a public school teacher in inner city Cleveland. She says they’re
trying to train students for these kinds of jobs, but they need direction from these new
companies…
“I teach in the third world known as the Cleveland Public Schools. I’m introducing
myself, so that if anybody needs kids, we got ’em. If you want to stop by and talk to me,
I’ll show you how to get kids, I’ll show you how to get in the door.”
Local universities and community colleges already have some research and training in
fuel cell technology. But mechanic Phil Lane looks at Cleveland’s poverty rate, the
highest among all big cities in the nation, and wants these companies to start training kids
even younger…
“We need to grab kids in the second and third grade, particularly in the very bad
neighborhoods, before the neighborhood can get to the kid. That’s what we really need to
do.”
Lane says training poor children early would provide a real foundation for a new
economy in Cleveland. Many communities that have lost their job base are starting
similar conversations and searching for ways to fit in to the global marketplace.

The Rust Belt regions of the United States are looking at new ways to make industrial
prosperity and environmental recovery work hand-in-hand. The Great Lakes Radio
Consortium’s Shula Neuman reports on an effort that could be a model for industrial
areas throughout the nation:
(sound of birds)
This area of Cleveland near the Cuyahoga River is where John D. Rockefeller first set up
his Standard Oil empire. The Cuyahoga is infamous for being the river that caught fire in
1969 and it became a symbol of the nation’s pollution problem.
Cleveland businesses and industries still live with that legacy. But through a new effort
called the Cuyahoga Valley Initiative, they’re trying to overcome it – although on the
surface it doesn’t look like there’s much happening.
Today, smoke stacks from steel plants still tower above head … below, like a jumble of
twisted licorice sticks, railroad tracks run through the meadows alongside the Cuyahoga.
Silos and old brick buildings line the banks of the river.
For Paul Alsenas, it’s an amazing place — not so much for what it has now, but for what it
can become. Alsensas is the director of planning for Cuyahoga County, the lead
organizer of the Cuyahoga Valley Initiative. The idea of the initiative is not to abandon
industry, he says, but to incorporate environmental and social principals into industry,
which could attract new businesses.
One of the more progressive aspects of the Initiative is something called “industrial
symbiosis.” Alsenas says industrial symbiosis works like natural ecology…
“An ecology of industry where nutrients flow from one form of life to another and make
it tremendously efficient and so therefore we have a competitive advantage. The
Cuyahoga Valley Initiative is not just about sustainability; it’s also whole systems
thinking, it’s also competitive strategy.”
Here’s how it works: waste from one company—a chemical by-product perhaps—is
used by a neighboring company to create its product. And that company’s product is then
sold to another company within the valley—and so on.
Alsenas says it’s already started: some companies located in the Cuyahoga Valley have
been sniffing out opportunities for sharing resources before anyone heard of the
Cuyahoga Valley Initiative. Joe Turgeon, CEO and co-owner of Zaclon, a chemical
manufacturer in the valley, says the Initiative sped things up.
“We pull all the members together and say, ‘OK, this is what I’ve got, this is what you’ve
got; here are some of the materials I need, here are some of the assets I have.’ And an
asset can be anything from a truck scale to a rail siding to by-product energy to
chemicals.”
Zaclon and its neighbor General Environmental Management have already begun their
symbiotic relationship. GEM now buys a Zaclon by-product, sulfuric acid, and in turn
Zaclon purchases a GEM byproduct. GEM president Eric Loftquist says the benefits go
beyond simply saving his company money.
“You know, we do business all over the country… but when you look around you see that
for every dollar you keep in this county, that generates taxes, generates jobs and the
benefits just keep rolling down. So you always want to look within.”
Loftquist says the Cuyahoga Valley Initiative encourages that effort. He says it’s
remarkable that it’s all coming together at the right time and with the right stakeholders.
It brings businesses together with government and area non-profits—including some
environmental groups—in a way not thought possible by industry and environmentalists
in the past.
Catherine Greener is with the Rocky Mountain Institute, a non-profit think tank that
studied the Cuyahoga Valley and is helping to get the initiative off the ground. She says
this area of the river—known as the regenerative zone could put Cleveland on the world’s
radar as a new business model.
“Cleveland has been known for being one of the seats of the industrial revolution and
what we’re seeing is a new industrial model that can emerge. How can you create
manufacturing jobs, industry jobs without jeopardizing the health and welfare of all the
people involved and also, to overuse a word, to ‘green’ the area around it?”
Greener says industrial symbiosis is a workable, practical solution because it makes
business sense… not just environmental sense…
“Sometimes I think about it as finding money in your pocket after you’ve washed your
pants. It’s always a bonus and you’ve always had it. And the resources that you have
here you’re just reinvesting in them and finding them and looking at them differently.”
The participants agree that “industrial symbiosis” won’t solve all the waste problems, but
it’s one part of a movement that’s making industrial cities re-think their relationship with
business and the environment.

Researchers are looking at ethanol from corn as an environmentally-friendly way to power fuel cells. However, some studies show corn-based ethanol takes more energy to produce than the fuel provides. (Photo by Lester Graham)
Researchers are looking at ways to use corn-based ethanol as a way to power hydrogen fuel cells. It would appear to be an environmentally friendly way to get into the hydrogen fuel economy. However, ethanol might not be as environmentally friendly as its proponents claim. Backed by the farm lobby and ag industries such as Archer Daniels Midland, ethanol has plenty of political support.

Researchers are looking at ways to use corn-based ethanol as a way to power hydrogen fuel cells.
It would appear to be an environmentally friendly way to get into the hydrogen fuel economy.
However, ethanol might not be as environmentally friendly as its proponents claim. Back by the
farm lobby and ag industry such as Archer Daniels Midland, ethanol has plenty of political
support. But some researchers say corn-based ethanol is a boondoggle. The Great Lakes Radio
Consortium’s Mary Stucky reports…
This reactor is in a laboratory at the University of Minnesota ticking as it converts ethanol into
hydrogen. Researchers here envision thousands of these inexpensive reactors in communities
across America using ethanol to create hydrogen, which would then be used in fuel cells to
generate electricity.
Lanny Schmidt, a Professor of Chemical Engineering, directs the team that created the reactor.
“We’re not claiming our process is the cure-all for the energy crisis or anything like that. But it’s
a potential step along the way. It makes a suggestion of a possible way to go.”
Hydrogen is usually extracted from fossil fuels in dirtier and more costly refineries.
Schmidt says it’s much better to make hydrogen from ethanol.
“It right now looks like probably the most promising liquid non-toxic energy carrier we can think
of if you want renewable fuels.”
Not so fast, says David Pimentel, an agricultural scientist at Cornell University. For years,
Pimentel has warned about what he calls the cost and efficiency and boondoggle of ethanol.
Pimentel says ethanol is a losing proposition.
“It takes 30-percent more energy, including oil and natural gas, primary those two resources to
produce ethanol. That means importing both oil and natural gas because we do not have a
sufficient amount of either one.”
Pimentel says most research on ethanol fails to account for all the energy needed to make the fuel,
such as energy used to make the tractors and irrigate crops. Adding insult to injury, says
Pimentel, ethanol relies on huge government subsidies going to farmers and agri-business.
“If ethanol is such a great fuel source, why are we subsidizing it with 2-billion dollars annually?
There’s big money, as you well know, and there’s politics involved. And the big money is leaking
some of that 2-billion dollars in subsidies to the politicians and good science, sound science,
cannot compete with big money and politics.”
Pimentel also points to environmental damage of growing corn – soil erosion, water pollution
from nitrogen fertilizer and air pollution associated with facilities that make ethanol. But
Pimentel has his detractors.
David Morris runs the Institute for Local Self Reliance in Minneapolis. Morris is not a scientist,
but he commissioned a study on ethanol. He says Pimentel relies on out-of-date figures and fails
to account for the fact that ethanol production is getting more efficient.
Morris’ findings – a gallon of ethanol contains more than twice the energy needed to produce it.
As for subsidies…
“There’s no doubt that if we did not provide a subsidy for ethanol it would not be competitive
with gasoline. But what we need to understand is that we also subsidize gasoline, and if you took
the percentage of the Pentagon budget, which is spent directly on maintaining access to Middle-
Eastern oil, and impose that at the pump, it would add 25- to 50-cents a gallon. At that point,
ethanol is competitive, under the assumption that you will not need a large military budget to
protect our access to Iowa corn.”
But more efficient than making ethanol from corn might be grass, or even weeds. David Morris
says that’s because you don’t have fertilize or irrigate those kinds of plants, the way you do corn.
“So if we’re talking about ethanol as a primary fuel to truly displace gasoline, we have to talk
about a more abundant feedstock. So instead of the corn kernel, it become the corn stock, or it
becomes fast-growing grasses, or it becomes trees, or sawdust or organic garbage. And then
you’re really talking about a carbohydrate economy.”
Pimentel scoffs at that idea.
“You’ve got the grind that material up, and then to release the sugars, you’ve got to use an acid,
and the yield is not as high. In fact, it would be 60-percent more energy using wood or grass
materials.”
While scientists and policy people debate whether ethanol is efficient or not, Lanny Schmidt and
his team soldier on in the lab undeterred in their efforts to use ethanol for fuel. Schmidt
understands some of Pimentels’s concerns, but he thinks scientists will find an answer, so ethanol
can be used efficiency enough to help power the new hydrogen economy.

A European semiconductor firm is developing a new kind of solar cell. They
hope it could make renewable energy competitive with coal and natural gas. The
Great Lakes Radio Consortium’s Richie Duchon reports:
Most solar panels use silicon semiconductors to convert the sun’s energy into
electricity. They’re the most efficient, but they’re also the most expensive. Right
now, solar energy costs about ten times more over a 20 year period than oil or
natural gas.
STMicroelectronics is developing a semiconductor made primarily of plastic. It
will be less efficient, but the company hopes that a significantly lower cost will
make it a competitive source of energy.
Salvo Coffa is the head of STM’s research and development.
“What we would like to see is to eliminate the first reason for not using the solar
cell, which is the high costs.”
Coffa and his team are still in the research phase, but he hopes that his company
will have plastic solar cells out by 2005.
