Some Senate Republicans want the climate
change bill to focus on building new nuclear
power plants. They’re calling for as many as
100 new plants in 20 years. But the industry
has been in decline for so many years now,
there’s concern there might not be enough
nuclear engineers to do the job. Julie Grant
reports:

There’s a lot of new interest in nuclear energy and technology these days. But there’s a problem.

The American Nuclear Society estimates they need 700 new nuclear engineers per year to keep up with growing the demand. It’s enough to give long-time nuclear supporters whip-lash. Until recently, things looked gloomy for the nuclear industry.

William Martin is chair of the nuclear engineering department at the University of Michigan. Ten years ago, he says no new plants were being designed or built. And he was having a tough time finding students.

“A student entering the field, what you could tell them was, ‘well, there’s a big focus on waste.’ That’s not hardly something that excites young students to enter the field.”

Martin remembers standing on the stage at graduation in the mid 1990s to call the names of his graduates. Other engineering departments had so many students, it took an hour to call them all. But Martin only had a few names to call.

“Our students trip across in about ten seconds.”

Lots of nuclear engineering programs didn’t make it through the down times. There are less than half the university programs today than there were 30 years ago.

Nuclear got a bad name starting in 1979 – with the meltdown at Three Mile Island in Pennsylvania. That was followed by the deadly nuclear accident at Chernobyl, Ukraine in the ‘80s.
By the early 1990s, President Clinton announced he would eliminate funding for nuclear power research and development.

Until recently, there hasn’t been an order for a new nuclear plant in 30 years.

Vaughn Gilbert is spokesman for Westinghouse Electric Company, which focuses on nuclear energy.


He says Westinghouse laid off a lot its engineers in the down years. A decade ago, those who were left were heading toward retirement. So, Gilbert says, the company started working with universities to train engineering students to run its aging nuclear plants.

“Simply because we knew we would need to attract new people to maintain the existing fleet and then also to work with our customers to decommission the plants as they came offline.”

Westinghouse and other nuclear companies started giving lots of money to maintain university programs.

And then, everyone started worrying about climate change – and looking for ways to make energy that wouldn’t create more greenhouse gases. Nuclear power has started making a comeback.

Gilbert says new plants are in the works again – and Westinghouse needs engineers. The company’s designs will be used in six new U.S. plants.

The timing is pretty good for 25 year old Nick Touran. He’s a PhD student in nuclear engineering at the University of Michigan. He knows there’s a negative stigma to nuclear power – because he’s asked people about it.

“I just say, ‘so what do you think about nuclear power?’ Just to passersby on the street. And one person said, ‘I only think one thing – no, no, no, no, no.’”

But Touran says the negative stuff mostly comes from older people. When Three Mile Island melted-down, Touran wasn’t even born yet. He says most people his age are much more accepting of nuclear power.

“It’s the people who remember Three Mile Island and remember Chernobyl and remember World War II, who have all these very negative associations with nuclear weapons and Soviet reactors that were built incredibly wrong. And stuff like that.”

Touran says much of his generation just sees a power source that doesn’t create greenhouse gases.

Of course, there are greenhouse gases created in the process of manufacturing nuclear fuel rods. And then there’s that pesky problem of that spent nuclear waste. There’s still no permanent place to dump it.

Touran says he started studying nuclear power because he was amazed by it. But as the number of students in his department grows, he says more are choosing nuclear because it’s a smart career choice.

Fighting Over Oil and Water

West a lot worse. It’s because energy companies hope to develop the oil shale industry.

In the future, keeping your gas tank full could make disputes over water in the American
West a lot worse. It’s because energy companies hope to develop the oil shale industry.
Getting oil from shale requires lots of water, and the richest oil shale deposits happen to be
in the dry state of Colorado. Shawn Allee headed there to see why a fight over water and
oil could be in the works:

Oil companies have their eyes on vast oil shale deposits in western Colorado, Utah and
Wyoming.

The federal government says companies could pull 800 billion barrels of oil out of that shale.

That’s about three times the proven oil reserves in Saudi Arabia.

Oil shale’s an impressive resource but it depends on water and there’s not much available
there.

How much would an oil shale industry need?

Shell Oil PR guy Tracy Boyd says the simple answer is that it will likely take his company
three barrels of water to extract one barrel of oil.

It’s because oil shale doesn’t really have oil in it – it’s got something called kerogen.

“You can heat this kerogen up. If you do it really slow, which we do for about 3.5 –
4 years, by putting heaters down in the rock formation, (you) produce a crude-oil
like material but with a little processing this is the first product we get out of it
which basically transportation fuels.”

Heating the ground require loads of electricity from new power plants and generators, and
they’d be cooled by water.

Oil companies are just experimenting with shale right now, but they’re securing rights to
water just in case.

Shell’s latest water claim is on Colorado’s Yampa River.

When Shell filed its court papers – some town governments warned they might fight the
claim.

One of these towns was Parker – a Denver suburb hundreds of miles east of the oil shale
region.

Frank Jaeger runs Parker’s water district.

Jaeger says, like other Colorado cities, Parker plans to expand.

“We know approximately what our numbers are and it will be somewhere in the
neighborhood of 150,000 people. In order to assure 150,000 people for another
150 years from now, I have to be proactive, I have to be at the front of the line for
the next drop of water available in the State of Colorado.”

Oil shale developers and cities across Colorado are set to fight over the water they might
need for the future, but some feel oil companies already have an edge.

“They’re actually one step ahead of the game.”

David Ableson is with Western Resource Advocates, an environmental group.

Ableson says energy companies tried developing oil shale several times in the last century.

They failed, but each time, they bought more water rights – just in case.

Now, they’ve got loads of water rights – and if the industry takes off, they’ll use them.

That could stop cities like Denver and its suburbs from getting water they hoped to have for
new homes and businesses.

Ableson says this isn’t just a Colorado fight, though.

He says some congressmen sell the idea of oil shale as an energy source the whole country
can depend on – even though its future could get tied up in Colorado water courts.

“And so, folks who are looking at this issue who do not live in CO, UT, or WY, need
to understand that when an elected official says, “this can solve our energy woes,”
that it’s actually a far more complicated situation than that and if there are severe
water impacts, that makes it much less likely that you could develop that
resource.”

The energy industry claims the concern over water is overblown – they say they just might
not need all that much water.

Ableson says that’s only true if oil shale fails. But if it succeeds, and we fill up on oil shale
gasoline – he predicts some towns or industries in the West will be left dry.

Learning to Live With Less Water

Droughts are nothing new for the Western US.
But lately, even some parts of the country
surrounded by water have gotten a taste of
droughts. Rebecca Williams reports as our
population grows, some experts say we’re going
to have to learn to live with less water:

(sound of birds)

Even in swampy, muggy Florida, people have been running out of water.

“This is the first time the well has ever gone dry.”

Ellen Peterson remembers water gushing out of her artesian well when she’d hook up the hose. These days she’s stuck with rusty water from her shallow well.

(sound of faucet turning on)

“Now if I let that sit it would settle out orange.”

We visited Peterson at the tail end of this year’s dry season. In the weeks since then, Florida’s been pummeled by major thunderstorms. But Florida water managers say it’s too early to know how much the rain will help.

This was the driest dry season Florida’s felt in more than 75 years. And it’s the third year in a row of serious drought. That’s meant some changes for people who live here.

Many cities put rules in place that limit watering lawns to one or two days a week. One woman actually ended up with a warrant out for her arrest after she watered her lawn on the wrong day and didn’t pay the fine.

Some cities in Florida are talking about adding a drought surcharge to bills for people using the most water.

Ellen Peterson says local water managers have even been capping wells in her area. Peterson may be 85 years old, but that didn’t stop her from telling her local official to back off.

“They told me they were going to cap my well and I threatened the guy with his life if he ever came back. (laughs) It hasn’t happened yet.”

So it’s not such an easy sell to get people to cut back on water.

(sound at a lake)

But that’s Gary Ritter’s job. He’s a water manager in the Lake Okeechobee area. It’s a giant lake – 35 miles wide – and it’s nicknamed the liquid heart of the Everglades. The lake level is 2.5 feet below average.

“For water to get to the Everglades it has to come from Lake Okeechobee. Now we have a juggling act as to how we manage this water in the system you know for multiple users for the water supply and for the ecosystem.”

The lake’s the center of a huge tug of war. Farmers and cities need the water, and the lake’s also a big tourist draw. And the Everglades are in major trouble – mostly because the water flow to this fragile area has been cut off by people.

Some experts say these kinds of conflicts are just going to get worse.

Peter Gleick is president of the Pacific Institute. It’s a nonpartisan group that studies water issues.

“Places we didn’t think were vulnerable to water shortages in the past are now increasingly vulnerable. As our population continues to grow and our water supply doesn’t. As more and more people try to share that fixed resource there’s going to be growing competition for water and more natural and manmade drought.”

And he says we just don’t know what’s in store for us as the climate changes because of global warming. We could get a one-two punch.

First, from weird new weather patterns. And second, from more and more people moving into dry areas.

People have expected these kinds of problems for cities in the desert Southwest. But nobody really saw this coming in the Southeast.

Peter Gleick says even if you live in a place surrounded by water now, you shouldn’t expect to always have plenty of it.

Shape-Shifting Fruits and Veggies

  • van der Knaap's team tests tomato starts for the SUN gene - the gene they isolated. SUN is responsible for tomato length. (Photo by Julie Grant)

Vegetables can be really odd shapes.
But what if you could alter fruits
and vegetables into just about any
shape you wanted? Some avid gardeners
come up with strange looking hybrids,
but Julie Grant talked with a researcher
who’s taking the shape of produce to
a whole new level:

Transcript

It’s time to start planting your garden this year. But maybe you’re tired of long, thin
carrots, huge watermelons, and round tomatoes. Julie Grant spoke with one researcher
who’s trying to give us some more options in the shape of fruits and veggies:

Ester van der Knaap steps gingerly around the greenhouse.

We’re at the Ohio State Agricultural Research and Development Center in Wooster.
The plants here are as tall as we are.

Van Der Knaap points out short, round tomatoes – and some odd-looking long, thin
ones.

“That’s one gene. One gene can make that difference.”

Van der Knaap’s team discovered that gene and isolated it. They call it the SUN gene.
And they’ve been able to clone it in tomatoes.

“You see this one is pretty round. It does not have the SUN gene. And that first one
makes a very elongated fruit, and it does have the SUN gene.”

Van der Knaap’s research could lead to square-shapes – something she thinks the
tomato industry might like. Square tomatoes fit better into packages. And, overall,
square tomatoes might be easier to work with than the common round tomatoes.

“They are mechanically harvested. So if you have a very round tomato, it would roll off
conveyor belts, it’s not very handy.”

So far money for her research has come from the National Science Foundation – not big
ag.

Van Der Knaap is quick to note – her tomatoes are not genetically modified.

You might remember the Calgene tomato which was made firmer by manipulating the
tomato genes with a gene from chickens. Van der Knapp’s just isolating the genes that affect the
shape of the tomatoes. Turning them on or off alters the shape.

Designer fruit shapes are gaining popularity. Check out any seed catalog, and there’s
a huge variety – some large and segmented, some pear-shaped, some oval, some
resembling chili peppers.

People have been cross-breeding tomatoes to make the shapes they want for a long
time. But this is not the same thing.

“It’s just funny, ‘cause my brother was working with some genetic things with tomatoes in
our attic.”

Dick Alford is a chef and professor of hospitality management at the University of Akron.

The difference between what his brother – and lots of other folks have been doing – and
what van der Knaap is doing is the difference between cross-breeding and locating a
specific gene that affects the shape of tomatoes.

The only other gene like this that’s been found so far was discovered by van der Knaap’s
advisor at Cornell University.

[sound of a kitchen and cutting veggies]

Chef Alford watches students as they cut yellow crookneck squash and carrots.

They’re trying to make uniform, symmetrical shapes out of curvy and pointed vegetables.
There’s a lot of waste. Chef Alford hates to see so much get thrown away. So he’s got
a request of Dr. van der Knaap.

“If we could get square carrots, it would be great. If you could get a nice long, a tomato
as long as a cucumber, where you could get 20 or 30 slices out of it, it would be great.”

In a country that loves hamburgers, Van der Knaap has heard that request before. But
the long, thin tomato hasn’t worked out just yet. She says there’s more genetics to be
studied.

Once we know all the genes responsible for making different shapes in tomatoes, Van
der Knaap says we’ll have a better idea of what controls the shape of other crops, such
peppers, cucumbers, and gourds.

And maybe then we’ll get those square carrots.

The federal government’s Energy
Star program is supposed to highlight
products that save you energy and money.
Rebecca Williams reports some independent
testers found Energy Star might be falling
a bit short:

The magazine Consumer Reports tests all kinds of products to see how they
stack up. They were testing refrigerators when they stumbled on something
odd.

Steven Saltzman is a Deputy Editor with Consumer Reports. He says the
Energy Star program relies on government standards that are outdated in some
cases. For example, one standard is to test a refrigerator’s energy use with the
icemaker off.

“But we found that when you turn the icemaker on – the refrigerator actually
used twice as much energy as it would with the icemaker off.”

Saltzman is not saying you can’t trust the Energy Star label. But he says the
tests need updating. And there’s a dark Energy Star secret, manufacturers get
to do their own testing in most cases – so there’s not a whole lot of third party
checking going on.

Exxon Valdez Oil Spill Lingers

It’s been more than 17 years since the Exxon Valdez split open on a reef off the coast of Alaska. More than 16,000 tons of crude oil washed up onto the rocky shores. Now scientists have found that the oil is still impacting the region’s ecology. The GLRC’s Mark Brush reports:

It’s been more than 17 years since the Exxon Valdez split open on a reef off
the coast of Alaska. More than 16,000 tons of crude oil washed up
onto the rocky shores. Now scientists have found that the oil is still
impacting the region’s ecology. The GLRC’s Mark Brush reports:


Scientists studied a series of islands that were the first to be hit by the
Exxon Valdez oil spill. It’s estimated that 100 tons of crude oil are still
impacting the region’s shorelines. The researchers found that about half
of the remaining oil is in the more biologically rich areas of the Prince
William Sound.


Jeffery Short is a research chemist with the National Marine Fisheries
Service. He says animals such as sea otters forage for food in these
areas:


“And if they were to encounter oil in their search for clams, it would get
on their fur, and since they rely on their fur to stay warm, they would
have to lick it off during preening and then they would ingest it.”


Short says this could be why the numbers of animals in this area still
have not rebounded since the oil spill. An Exxon spokesman told the
Associated Press that they believe the Prince William Sound has
recovered.

Bird Song Mystery Revealed

Scientists have come one step closer to understanding how birds
create their songs. The Great Lakes Radio Consortium’s Rebecca
Williams explains:


(dove song)


That’s a cooing ring dove. And this is a recording of special muscles
the dove’s using to control its song: (sound of muscle activity).


Those muscles are called aerobic superfast muscles. It’s a type of
muscle that has been found in rattlesnakes and some fish. The
muscles were just discovered in birds for the first time.


The research was published in the journal Nature. Coen
Elemans is the lead researcher. He says a unique quality of the dove’s
song led him to investigate it further.


“And we found that some of these doves have a trill in their song, they
make a sound something like (mimics dove song). And during this
short trill, you get elements that are so short, sometimes ten or nine
milliseconds, that I was wondering, how can this be done? This is so
fast that normal locomotory muscles you find in vertebrates cannot do the job.”


Elemans says this discovery could be just the beginning. He says
songbirds have more complex vocal systems than doves… so
songbirds could be using even faster muscles.
