Even though General Motors has filed for bankruptcy, Rebecca Williams reports the company is still dreaming big:

Someday you might be able to power your radio through your car’s paint.

Christopher Webb is GM’s senior creative designer.

He says GM’s research teams are giving some thought to solar powered paint. He says it might start with tiny solar cells called quantum dots.

“You could suspend these solar cells in a resin system or a waterborne or solvent carrier and spray it over the surface of the vehicle. Technically the entire surface of the vehicle could become almost a solar conductor.”

Webb says nobody knows exactly how this might work yet. But he says he’s confident that GM will continue their research into new technologies like this even with the bankruptcy announcement.

Something else that’s being talked about is using volcanic rock in paint. It could be a coating that would reduce a car’s interior temperature by reflecting heat – so you could use the air conditioning less often.

Researchers are working on a tool
that could tell you if your food is safe
to eat before you break open the bag.

A team at Tufts University is working on sensors that could change color to
tell you if a bag of lettuce has dangerous bacteria in it.

The special ingredient is silk. They boiled silkworm cocoons. And made a
thin silk film out of the proteins. The silk film has color changing properties
– like a butterfly’s wing.

Fio Omenetto is the lead researcher. He says it could be possible to activate
the film so it detects the presence of E. coli. Then the film could be put in a
bag of spinach.

“So immediately by looking at color change you will be able to tell whether
the spinach is good to eat or not.”

Omenetto says this is still pretty futuristic at this point. He says it’ll
probably be at least five years before you might see this at the grocery store.

The Color of the Environmental Movement

  • Many hope that the future generations of envionmentalists and conservationalists will include more minorities. That's why the National Wildlife Federation now has a program to encourage youth and adult minorities to learn about and adopt careers in environmental fields. (Photo by Hans-Günther Dreyer)

The environmental movement and conservation agencies tend to be very white. There are relatively few people of color involved in environmental activism or getting jobs in resource management. If one man has his way, that will change in the coming years. The Great Lakes Radio Consortium’s Lester Graham reports:

The environmental movement and conservation agencies tend to be very white. There are relatively few people of color involved in environmental activism or getting jobs in resource management. If one man has his way, that will change in the coming years. The Great Lakes Radio Consortium’s Lester Graham reports:


If you happen to go to a national conference of environmentalists, or conservation-minded organizations, you probably wouldn’t see a lot of black faces… or Latino… or Asian. Oh sure, a few sprinkled here and there, but mostly, it’s white folks.


But that’s beginning to change. Jerome Ringo is the chair-elect of the National Wildlife Federation. He will be the first African-American to head up a major environmental organization. He says times are changing.


“We are seeing a reversal of the trend. We’re not where we want to be with respect to minority involvement in conservation, but I can guarantee you we’re not where we were. Years ago when I got into the environmental movement, there were very, very few minorities involved.”


Ringo is working to keep the trend reversed. Through the National Wildlife Federation’s youth program, Earth Tomorrow, he’s encouraging young African-Americans and other minorities to learn about the environment and conservation.


And a few young people are listening. Kenneth Anderson is a college student, studying to be an ornithologist. He’s something of a rare bird himself. He grew up in the city – in Detroit – where he says a lot of his friends and neighbors are not all that interested in nature and the environment.


“Really, I mean I can understand why people wouldn’t because throughout most of their life, they’re in this urban setting away from as much wildlife or forests or anything like that so they don’t look at the environment as something of importance because in a way it’s already been taken away or hidden from them. So, that’s why you don’t have a lot of people of color or minorities involved in environmental fields.”


Being cut off from nature is only one obstacle. There are others. Kiana Miiller is a high school student in Detroit. She says a lot of kids are worrying about more pressing problems…


“People of color are in urban areas and urban areas have a lot of different problems like financial issues, stuff like that. So, environmental issues may not be number one on their priority list.”


Kiana Miller and Kenneth Anderson are among a handful of young people of color who are at a meeting to hear from activists and people working in wildlife management about getting involved in environmental issues… and getting jobs.


Like a lot of the kids, many of the speakers at this meeting grew up in the city. For example, Monica Terrell says she didn’t know anything about nature until someone took her on a camping trip when she was a kid. Now, she’s with the Michigan Department of Natural Resources working with state parks all over. She’s at this meeting recruiting.


“People of color and also women need to be made aware of the career opportunities. When you look at different fields, you usually look at people that you know who are already in those fields. You may have a father who is a doctor, a friend who is an attorney, teachers, plumbers, what have you. But we don’t have very many people of color and women who are already in those fields. And so, that’s why it’s so important for us to go out to recruit, select, hire these folks, mentor them, make sure they have a comfortable, successful experience in natural resource management fields.”


Getting the message of environmental involvement doesn’t stop at getting young people thinking about their options. The National Wildlife Federation’s Jerome Ringo says it also means getting grown-ups, especially the poor and people of color, to get active in their community when there are environmental problems. He says he first got involved in environmental activism because he knew of chemical releases that were being emitted from a refinery, and some of those chemicals could cause health problems for the people who live nearby – most of them low-income African-Americans.


“We have to readjust our priorities from just quality of life issues like where next month’s rent is coming from, how do we feed our family. Environmental issues have to be within our top priorities because, as I tell the people in ‘Cancer Alley,’ Louisiana, what good is next month’s rent if you’re dying of cancer? So, we’ve got to be more involved in those quality of life issues and make environmental/conservation issues one of those key issues in our lives.”


Ringo says whether it’s fighting pollution, or a desire to preserve a little of the remaining wilderness, people of color need to take hold of environmental and conservation issues, and make them their own.

The Foibles of Suburban Lawn Care

One of the great rituals in suburban America is mowing the lawn. A
manicured lawn seems to say that the house is well cared for, that it belongs
to the neighborhood. Great Lakes Radio Consortium commentator Ed
Herrmann wonders whether this obsession with the perfect lawn is worth the
effort:


(sound of evening insects)


It’s a late summer evening and at last I can go outside and enjoy the
sounds of the neighborhood. There’s a little breeze, the air is cooler. The
chorus of insects is soothing, gentle but insistent, an ancient throbbing
resonance. Much better than during the day…


(roar of lawn machines)


Summer days in the suburbs are the time of assault, when people attack their
lawns with powerful weapons from the chemical and manufacturing
industries. Anyone who uses the words “quiet” and “suburbs” in the same
sentence has never been to a suburb, at least not in summer.


It takes a lot of noise to maintain a lawn. Besides the mower, you’ve got edgers, trimmers,
leaf blowers, weed whackers, core aerators, little tractors, big tractors, slitting
machines. I don’t know whatever happened to rakes and hand clippers. One
thing’s for sure. This quest for lawn perfection wouldn’t be possible without
the industrial revolution.


(machines stop)


So where did we get the idea that a house should be surrounded by a field of
uniform grass kept at the same height?


Well, with apologies to the Queen, I’m afraid we must blame the British. It
seems that, along with our language, our imperial ambitions and our
ambivalent morals, America also gets its notion of what a lawn should look
like from the English. Of course, the estates of the English aristocracy were
tended by a staff of gardeners. England also has a milder climate, and the
grass that looks so nice there doesn’t do as well in North America. In the
1930’s the USDA came up with a blend of imported grasses that would
tolerate our climate. Since these grasses are not native, they need help, and
that calls for fertilizers, pesticides and lots of extra water. Since normal
people can’t afford gardeners who trim by hand, that means lawn machines.
American industry to the rescue.


(mower starts up, fades under next sentence)


A quick Google tells me that today we have 40 million lawn mowers in use.
Each emits 11 times the pollution of a new car, and lawn mowers contribute
five percent of the nation’s air pollution. Plus more than 70 million pounds of
pesticides are used each year and over half of our residential water is used
for landscaping. Don’t you love those automatic sprinklers that come on in the
rain? Add to that all the time that people spend mowing and edging. Of
course the two billion dollar lawn care industry is thrilled about all this
enthusiasm, but I gotta ask, “Is it worth it?”


Call me old fashioned, but I actually prefer the looks of a meadow with mixed
wildflowers and grasses to the lawn that looks like a pool table. My own lawn
is somewhere between. It’s mowed, but it’s what you might call multicultural.


There are at least five different kinds of grass with different colors and
thicknesses, plus clover, dandelions, mushrooms, a few pinecones, and a
rabbit hole or two. There’s also some kind of nasty weed with thorns, but even
that has nice purple flowers if it gets big enough.


Clover, by the way, used to be added to grass seed because it adds nitrogen to
the soil. Now we just buy a bag of nitrogen fertilizer, so who needs clover?
And what’s wrong with
dandelions? You can eat them, some people even make wine out of them,
they have happy yellow flowers; yet to most people they indicate your yard is
out of control. So I’m down on my hands and knees pulling dandelions. I’m
not sure why, but I hope it keeps the neighbors happy.


One thing I won’t give in to, though, is the chemical spraying trucks, painted
green of course, that roll through the neighborhood.


I can only hold my breath. (sound of trucks and mowers) Try not to listen. And
wait for the evening. (evening insects)


(air conditioner starts up)


Although, with all these air conditioners, even the night’s not too quiet.


But that’s another story.
