We hear a lot about the coming
hydrogen economy. Hydrogen has a lot of
promise because it’s a clean burning gas.
But, for the most part, you have to burn
dirtier fossil fuels to make hydrogen.
Scientists can produce hydrogen from water.
But the process is expensive. Julie Grant
reports on new science that has researchers
buzzing:

MIT researcher Daniel Nocera has found a cheaper way to get hydrogen
from water molecules. Researchers already have been able to do this – but
only with a precious metal – platinum. It costs nearly $2000 an ounce.

Nocera’s team discovered a material based on cobalt that does the same job.
Cobalt costs more like $2 an ounce.

James McCusker is an expert on solar energy conversion at Michigan State
University. He says the discovery has researchers excited.

“A, it works. But B, it works in such a way that it’s very, very easy to put
together. And it’s made of very inexpensive materials. They’re really
potential game changers in this field.”

McCusker says there’s still a lot of work left before we’re ready for a
hydrogen economy.

The new research was published in the journal Science.

The candidates for president and vice president have spent a lot of time talking about security, the economy, and health care. They have not spent much time talking about the environment. As part of a series on the records of the presidential and vice presidential candidates, the Great Lakes Radio Consortium’s Lester Graham reports on Democratic challenger Senator John Kerry:


Senator Kerry considers himself an environmentalist. Kerry’s Senate office website indicates that
30 years ago, he spoke at his home state of Massachusetts’ first Earth Day. The Senator says he
called for “fundamental protections that became the Clean Air Act, Clean Water Act, Safe Drinking
Water Act, Endangered Species Act and Superfund.” However, he doesn’t often talk about how he
would handle the environment. Early in the campaign in this speech in Minnesota, he promised to
be a guardian of the environment and he briefly outlined his energy plan…


“I will set a goal as president that 20 percent of all of our electricity will be provided from
alternatives and renewables by the year 2020. And I will set this country on the course by creating a hydrogen institute, by putting a billion dollars into the effort of conversion of our autos, by moving to a 20 billion dollar support for the conversion of our industry, we are going to guarantee that never will young American men and women in uniform be held hostage to our dependency on Mideast oil. We’re going to give our children the independence they deserve.”


When the topic of the environment came up during the second presidential candidates’ debate,
Senator Kerry didn’t outline his own plans, but instead responded to President George Bush’s
claims that the environment was cleaner and better under the Bush administration.


“They’re going backwards on the definition for wetlands. They’re going backwards on water
quality. They pulled out of the global warming. They declared it ‘dead.’ Didn’t even accept the
science. I’m going to be a president who believes in science.”


During the negotiations on the Kyoto global warming treaty Senator Kerry went to Kyoto and
worked to craft a plan to reduce greenhouse gases that could pass political hurdles in the U.S. He
was a leader in the effort to stop a Bush proposal to drill for oil in the Arctic National Wildlife Refuge in Alaska.


Environmental groups like what they see and have been enthusiastic about their support for the
candidate. Betsey Loyless is with the League of Conservation Voters…


“Senator Kerry, who has, by the way, a 92 percent lifetime LCV score, has quite a remarkable
overall consistent record of voting to protect clean air, clean water and protect our natural
resources.”


But while the environmentalists like John Kerry, some business and industry groups that feel the
federal government’s environmental protection efforts have become burdensome and ineffective
aren’t that impressed…


“Well, John Kerry – yeah, he got a stronger LCV rating than even Al Gore. Now, pause and think
about that, okay?”


Chris Horner is a Senior Fellow with the Competitive Enterprise Institute, a free-market think tank. Horner says he doesn’t like many of Kerry’s positions, but adds he doesn’t think Senator Kerry’s environmental record is as strong as the support from environmental groups might indicate…


“Let’s just say that a lot of the support that comes for Kerry is not through leadership he’s shown in the Congress because he really hasn’t. It’s that he says the right things and that his wife certainly puts the money in the right place.”


Horner suggests that Teresa Heinz Kerry has given large sums of money to environmental
groups… and Horner thinks that’s helped her husband’s political career. Whether you give
credence to those kind of conspiracy theories or not… it’s clear that the environmental groups
prefer Kerry over Bush. The Kerry campaign’s Environmental and Energy Policy Director,
Heather Zichal, says the environmentalists like him… because of his record.


“He’s been called an environmental – dubbed an “environmental champion” and has received the
endorsements of everybody from the Sierra Club to Friends of the Earth. And for him, you know,
environmental protection is not only a matter of what’s in the best interest of public health, but it also is what’s in the best interest of our economy going forward. George Bush has given us the
wrong choices when he says you have to have either the environment or a strong economy. John Kerry believes we can have both.”


But the environment has not been a major issue in the campaign. Conventional wisdom seems to
indicate those who are prone to support pro-environment candidates are already on-board with
Kerry… and the undecided voters have weightier issues on their minds.

Books can be powerful. Sometimes they can even change your life. As part of our ongoing
series on individual choices that impact the environment — “Your Choice; Your Planet” —
the Great Lakes Radio Consortium’s Curtis Gilbert brings us the story of one book that
changed his mother’s life…a book that so profoundly affected her that she felt compelled
to share its teachings with strangers. It wasn’t the Bible or the Koran… or “Chicken Soup
for the Soul.” And the part of his mother’s life that it changed is one so exceedingly private
that most people don’t even like to talk about it. He’ll explain:


There’s a sound — something familiar to everyone who lives in a Western, industrialized
country — but it’s a sound you’ll almost never hear at my mother’s house.


(sound of toilet flushing)


Five years ago, my mom turned off the to water to her toilet. She put a house plant on top
of the seat and opposite it built a five-gallon bucket in a box that took over all the duties
of its porcelain counterpart.


“Well I had seen ‘The Humanure Handbook’ in the FEDCO Seed catalog — and it just sort of
intrigued me. And I decided one year that I would read it since I was curious about it year after
year. And I read it and then I began to feel really bad every time I flushed the toilet.”


That’s because every time my mom flushed the toilet she was rendering undrinkable several
gallons of otherwise perfectly good water. And what’s more, she was whisking away valuable
nutrients that she could have just as easily returned to the earth.


That’s right… Humanure is a contraction consisting of two words: human and manure.


Here’s how it works: You use the humanure bucket in pretty much the same way you’d use a flush
toilet. Everything’s the same, except that instead of flushing when you’re done, there’s another
bucket right beside the humanure bucket and it’s filled with sawdust. You use a little cup to
scoop up some sawdust and then you just dump the sawdust in the humanure bucket when you’re
finished using it. That’s it. And the crazy thing, the thing that always surprises people when
I tell them about my mother’s humanure project is that it doesn’t smell bad.


“Anytime anything’s stinky in the humanure, you just cover it with sawdust and it doesn’t stink
anymore, except of course what is already in the air, which is like any toilet.”


Once a day my mom takes the bucket brimming with sawdust and humanure and dumps it into her
massive compost pile. There, it mingles with her kitchen scraps, weeds from the garden, and
just about every other bit of organic matter she can find… and in two years time the humanure
cooks down into dark, rich, fertile soil.


For the first couple of years, my mom was content just to operate her own humanure compost
heap and let her garden reap the benefits — but the more she did it the more of a true believer
she became. Strict adherence to the faith wasn’t enough for her anymore. She had to become a
missionary. She bought a case of Humanure Handbooks and set up a booth at an organic gardening
festival called Wild Gathering.


“And I think I sold one at that Wild Gathering. And then after that I was giving them away right
and left to my sisters and nieces and friends and whoever! And I used them all up and then this
last year I decided that not only was I going to get another box of Humanure Handbooks, I was
going to collect humanure at Wild Gathering!”


My mom knew she’d a lot of buckets for the project, so went door to door at the businesses
in town. She didn’t say what she needed them for, and luckily they didn’t ask. She collected eight
buckets full in all — not quite the payload she was hoping for. Attendance at Wild Gathering was
pretty low that year, due to rain, but relatively speaking, sales of the Humanure Handbook were
way up.


“I sold more at this last Wild Gathering. I think I sold five or six. And I gave one away for
Christmas this year to Natasha, who had been having plumbing problems. And I started my spiel and
she was really quite interested. And, I think we may have a convert there before long.”


Conversion. The ultimate goal of any evangelist. My mom admits that she doesn’t know of anyone
she’s actually brought into the fold — but she likes to think she’s planting seeds. Just
introducing people to the idea that there’s a alternative to flush toilets, she says, is a huge
step forward.


“This is really a shocking idea to a lot of people and a lot of people who come to the house will
not use it. I have to make the water toilet available to them.”


My grandmother won’t use it. Neither will my mom’s friend, Rochelle. And then there’s my
girlfriend, Kelsey. Last summer the two of us spent several days at my mom’s house in Maine
before taking a road trip back to where we live in Minnesota. After quietly weighing the
ramifications of sawdust versus water toilets, Kelsey finally decided to brave the humanure…
well, sort of.


Curtis: “So you used it for some things, but you’ve told me before that there were some things
that you couldn’t bring yourself to do.”


(laughing)


Kelsey: “No, I couldn’t. I did not have a bowel movement during our entire visit to your
house, over the course of four days.”


I’d like to think that Kelsey’s physical inability to make full use of the sawdust toilet
was an anomaly, that most people would have no problem going to the bathroom at my mom’s house
in Maine… But I doubt that’s the case. And that’s not the only reason I’m a little skeptical about
my mom’s vision of a world humanure revolution.


Curtis: “It occurs to me, and I’m about 100 pages into the book at this point, that this is
all well and good for people living in rural areas, but I live in a city. Where am I going to
put a compost heap?”


Mom: “You know, there could be chutes in buildings. There would have to be temporary storage.
Trucks would come in and take it out. Great huge compost piles would be built and it would work
down very… I think that where there’s a will, there’s a way.”


I’ll admit it; I’m still skeptical. I mean I believe in humanure, sure. But I also haven’t
put a house plant on top of the toilet in my big city apartment…and I probably never will.
Call me a summer soldier in the humanure revolution if you will, but when I go home to my
Mom’s next Christmas, I’ll be flushing with sawdust and I’ll be proud.

Power Company Switches to Natural Gas

The Bush administration is making it easier for coal-burning power plants to avoid upgrading to modern pollution prevention equipment. But in some cases the power companies are bowing to public pressure to reduce pollution anyway. The Great Lakes Radio Consortium’s Ann Alquist reports:

The Bush administration is making it easier for coal-burning power plants to avoid upgrading to
modern pollution prevention equipment. But in some cases the power companies are bowing to
public pressure to reduce pollution anyway. The Great Lakes Radio Consortium’s Ann Alquist
reports:


Elizabeth Dickinson didn’t get any kind of warning about air quality in her neighborhood. She
really didn’t need one. She says couldn’t avoid noticing the pollution in the air.


“A couple years ago, there was almost a week where the air quality in my neighborhood was so
bad that you literally couldn’t sleep. There was a burning back in my throat.”


Dickinson lives in Saint Paul, Minnesota, not too far from one of the oldest coal burning plants
operated by Minnesota’s leading supplier of electricity, Xcel Energy.


She and many other people have been actively working to pressure the company to address the air
quality problems they believe are caused by Xcel’s older plants.


And in a rare move among power companies, Xcel Energy is doing something. In May 2002, the
company put forth a voluntary proposal to convert its two oldest coal burning plants to natural
gas. The oldest plant, Riverside, lies in northeast Minneapolis.


(sound of power plant)


Since it opened in 1911, the Riverside plant has changed very little when it comes to emitting
pollutants. It was grandfathered in under the Clean Air Act of 1970 – which means the plant isn’t
subject to federal environmental mandates.


It didn’t have to install modern pollution control devices unless it upgraded the plant. And now,
under the Bush administration’s new rules, even upgrading it might not trigger the threshold that
would require it to reduce emissions.


“For a little bit over two years, one of the first things I was charged with was to look at all the
emissions in and around southeast Minneapolis and Riverside plant came back as a sore thumb
because of the glaring emissions.”


Justin Eibenholtz is the environmental coordinator for a Minneapolis neighborhood improvement
group. He says that’s why Excel’s decision to convert Riverside to natural gas is such a big deal.
Once it’s converted, the old plant will cut air pollutants by 99 percent. Mercury emissions will be
completely eliminated.


Neighborhood groups such as Eibenhotz’s and big environmental groups alike are praising
Excel’s decision. The Great Lakes Program Coordinator for the Sierra Club, Emily Green, says
the reduction in emissions will mean a better quality of life for residents who live in the Great
Lakes region. That’s because the mercury and other pollutants that were emitted from the plant
often ended up in the Great Lakes through a process called air deposition. That meant pollutants
got into the food chain and contaminated fish.


“The Great Lakes are like a giant bathtub with a very, very slow drain, so that what we put into
the Great Lakes stays there.”


Green says the pollutants don’t go away. They just end up contaminating the air and the water.


“We swim in them, we drink them, you know, the fish swim around in them, and so it’s very,
very important that we recognize, despite their size, how fragile the Great Lakes are.”


Besides polluting the lakes, the air pollution drifted for hundreds of miles, causing health
problems. The effects are already apparent. An independent report commissioned from the
Environmental Protection Agency says pollution from the oldest and dirtiest power plants kills
more than thirty thousand Americans each year – almost twice the number of people killed by
drunk driving and homicide combined.


While the natural gas conversion won’t reduce the level of mercury in the Great Lakes
immediately, it will mean it won’t add to the problem. It also means a more efficient use of a
fossil fuel.


Ron Ellsner is the project manager for Xcel’s proposal.


“The new combined cycles that we’re going to install are on the order of 30 percent more
efficient than what our current coal cycle is. They do that much better a job converting that
energy into fuel into electricity.”


It comes at a cost, though. Xcel estimates converting its Minneapolis and Saint Paul plants will
amount to one billion dollars. By Xcel’s estimate, it’ll be the most expensive power plant
conversion in the history of the United States, and the cost of the conversion will be passed on to
its customers.


That’s fine by Elizabeth Dickinson. She says she, and her neighbors, were paying for it in other
ways already, such as additional healthcare costs. Dickinson says the estimated extra 15 cents a
day for her power bill will be worth it.


“You know, these are the hidden costs of coal burning and they’re huge, and you know, they’re
usually left out of these equations and we’re saying they can’t be left out any longer, they just
can’t be, because it’s too high a cost for us as a society.”


Government regulators still have to approve the plan. Minnesota’s utilities commission is
holding a final round of public hearings before voting for or against Xcel’s proposal to convert to
natural gas.


If the conversion is approved, it will likely put pressure on other power companies in the Great
Lakes region to do the same.

A power company in the Great Lakes region is dramatically reducing pollution at two of

cost of the conversion – one billion dollars – will be passed on to Xcel’s customers.

It will mean a 99 percent reduction in emissions – and mercury emissions will be

no longer marring the skyline.

Ron Ellsner is the project manager for Xcel’s proposal.

“Cleaning up some of the older equipment that will be abandoned, we hope it has a
positive impact on the landscape for our city and for our neighbors.”

If government regulators approve the proposal, it will likely put pressure on other power
companies in the Great Lakes region to do the same.
