Saving energy can be as simple as turning off the light switch when you leave a room. But in most homes… that doesn’t happen all the time. Lester Graham reports… motion sensing light switches are become more popular because they’ll switch on and off automatically.

In some families, Dad stomping around the house, turning off lights and yelling to no one in particular is legendary.

“How many times do I have to tell you, turn off those lights.”

Don’t burst a blood vessel there, pal.

Well, Dad might have had a point. Matt Grocoff with Greenovation.TV says he’s been poking around the Environmental Protection Agency’s website and found this:

“Sixty-percent of lighting actually goes to lighting an unoccupied room, hallways, bathrooms, your bedroom. Drive by any neighborhood house and you’ll see eight rooms lit. How many of those houses have eight people in them.”

Matt says there’s a solution. Motion-sensing light switches. They can be set to turn on when you walk into a room and turn themselves off when you leave… staying on for a minute or two… or five… or a half-hour. Whatever you set it to.

There are a lot of different types. Laurie Gross is President of Gross Electric in Ohio and Michigan. They’ve been selling lamps and lights and switches for one-hundred years.

She says there are light switches that turn on when you enter and off when you leave, others that you have to turn on and they turn off when the room is empty. Different technology works –well– differently. Gross says passive infrared works well for pantries or kitchens because they detect motion.

“Then there’s ultrasonic which doesn’t need a line-of-sight. So, those are good in public bathrooms so when it senses heat, when go in there, it knows you’re there and turns off if you take a little longer than expected to take.”

And there are switches that use both infrared and ultrasonic… good for places like big office spaces.

You can expect to spend 50 – 60 bucks or more for a good one, depending on what you want. There are cheaper sensor light switches out there… but in this case, you really do get what you pay for.

Now… these switches use a tiny bit of power themselves… so the best place for them is in a room where leaving the light bulb on is not likely to be noticed for a while. Matt tells the story of forgetting to turn off a light in the garage during vacation. That bulb burned for two weeks. A sensor switch makes a lot of sense in a place like that… or in a closet… or a room you don’t use a lot.

Matt Grocoff and his wife Kelly are working to make their 110 year old house the oldest net-zero energy home in America. And he says he loves having motion sensing switches in key areas for the convenience as well as the energy savings.

“We open the door in the kitchen and come through the door with loads of groceries and the light comes on automatically. You don’t have to do the elbow dance.”

His wife Kelly says for her… it’s avoiding a little childhood terror.

“I have a little PTSD from when I was younger and my Dad was constantly harassing us to turn the lights off. Now, I know if I leave the room and I don’t turn the light off, it’s going to go off eventually instead of having my Dad chase me down and giving me some lecture about turning the lights off, saving energy, saving money, blah, blah, blah.”

Funny story about that. Kelly’s Mom, Jane Casselman was visiting when I was at the couple’s house… and she started laughing about Dad lecturing about the lights.

“’Cause in the evening, yours truly would turn all the lights off before going to bed.”

Heh– busted.

New technology might help the US
Forest Service detect fires in remote areas
more quickly. Lester Graham reports:

A chemical reaction makes batteries generate electricity. There’s a ph difference
between trees and the soil around them. MIT researchers say they can use that
chemical difference to generate a tiny amount of electricity.

Andreas Mershin and his MIT colleagues say it’s just enough power to trickle charge
sensors that read temperature and humidity. Then they send that data to the U.S.
Forest Service so it can determine the risk of fire.

“The advantage comes from the fact you no longer need to be going to very remote
locations and changing batteries all the time.”

The Forest Service will be testing these sensors next spring. They cost about one-tenth
of other sensors that need batteries. So it could mean more sensors in remote
locations. That way the Forest Service could have a better idea of if and when it needs
to put fire equipment near hot, dry areas.

Rust Belt City Desires High Tech Future

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.

Water is of growing concern to people in the Great Lakes region, especially after this summer’s widespread drought. Now, researchers are testing a device that could help Midwest farmers decide the best way to manage their water. The Great Lakes Radio Consortium’s Rebecca Williams has more:


The device is called an electron moisture sensor. It measures the amount of moisture in soil, as deep as 3 feet below the surface. The sensor is hooked up to a hand-held computer that brings together soil data with information about weather and the type of crop being raised.


Rich Hoddup is an agriculture extension agent with Michigan State University. This year, he recruited several farmers to test the moisture sensor. He says the farmers are reacting to the system with optimistic caution.


“They’re looking at it and saying, well, it’s kinda nice to be able to understand what’s going on below the soil profile, rather than waiting until that crop begins to show symptoms of drought.”


Rich Hoddup thinks the sensors may allow farmers to increase their yields, by telling them when and where to add water to their crops. He plans to continue his research to see if the benefits to farmers will outweigh the high cost of the system.
