Soon, you’ll be able to buy
a sort of raygun to detect heating
leaks in your home. Jessi Ziegler reports on a Thermal Leak
Detector:

This tool looks like a little toy raygun, and it shines beams of light
that read the temperature around your house.

Scott Pollard is the Senior Product Manager at Black and
Decker, which makes the tool. He says it’s really easy to use.

“Shine it on the wall, it starts off with a green light, and as they
move it from their wall to their window, or door, or around pipes,
or floor, or ceiling, the color will change to red if it hits a hot spot,
or blue if it hits a cold spot.”

And, if you think you the little leaks don’t really matter, well,
Pollard’s research shows that if you add up all the little cracks
and leaks in a typical home, it equals a hole the size of a
basketball.

The EPA says that homeowners can save 20% on their heating
and cooling costs if they seal air leaks and insulate their houses.

Asphalt is usually made with oil.
The rising price of oil has made it more
expensive to repave roadways. Now some
cities are starting to give green alternatives
a chance. Julie Grant reports:

Cities use asphalt to reseal old roads. It oozes in and fills
the cracks, extending the life of the pavement.

But the price has gone up 200% in the last two years.

Paul Barnett is director of the Akron, Ohio Public Works
Bureau.

This year he plans to try a soybean-based sealant. Barnett
says now it costs about the same oil-based asphalt, but the
road runoff is better for the environment.

“So you have a soybean oil that’s biodegradable instead of a
petroleum product that’s going into the streams and creeks,
rivers.”

The cost of soybeans has also been increasing – for food,
for fuel, and now for things like pavement.

Barnett figures if soybean oil becomes popular, it will drive
the price higher, but for right now it’s a good alternative to
asphalt on some roadways.
