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.

Study: Coffee Dates Best

A study published in the journal
Science suggests that there might be a link
between how warm you are and how much you
like someone. Jessi Ziegler reports:

The study was really simple.

Researchers pretended to have their hands really full, and
asked people to hold their coffee for them. Some of the
coffee was iced, some was hot. The people were then
asked to rate others’ personalities.

You know, like in terms of being a “warm” person or a
“cold” person.

They discovered that those who held the hot coffee rated
people as warmer. The people who held iced coffee? Not
so much.

Lawrence Williams at UC Boulder is co-author of the study.

He thinks this has to do with associations made when
you’re a baby. Your first concept of social warmth
coincides with physical warmth.

So, what does this study mean for you?

“This work suggests that going out for coffee might be
effective in getting the relationship off on the right foot,
as opposed to going out for ice cream, for example.”

You heard it here. Coffee dates are a much better bet.

A New Bulb on the Block

Unless you like to live by candlelight,
you have to buy lightbulbs. But the options
out there aren’t that great. Jessi Ziegler reports how all that might change soon:

Plain-old incandescent lightbulbs are not efficient. That’s
old news.

And fluorescents? The color is funny and they have toxic
mercury in them.

So, what option is left?

LED lights. They’re as efficient as compact flourescents
minus the mercury.

The problem? They’re one-hundred-dollars-a-bulb
expensive.

But scientists at Purdue have been working on a way to
cut that cost.

Researcher Timothy Sands says in about 5 years, LEDs could
cost the same as the other bulbs.

“So, the nice thing about it is you can save energy, and
actually save money over the long haul – even though the
initial cost is very high right now, without changing what
you’re used to, or without lowering your standards for
lighting.”

And Sands says another big advantage of LEDs is you’d only
have to change the bulbs every 15 years.

Trees as Odor-Eaters

As suburbs are built closer to
farms, there are sometimes complaints
about the odors. Researchers are now
working to smooth things out between
farmers and their new neighbors. Jessi
Ziegler has the story on one
of the simple solutions they found:

If you’ve ever driven by a chicken farm, you know the
smell can get pretty bad.

So, imagine living by one, and smelling it every single day.

Well, researchers may have come up with a solution –
trees.

Planting a few rows of trees around a farm can do all sorts
of good.

They capture dust and ammonia. And they block noise
and odor.

Also, they make the farm look a lot prettier. Which,
researcher George Malone says, can make a big difference.

“There’s been other studies to indicate that attractive
farms, statistically, have less odor than unattractive farms.
Perception is reality of what we deal with.”

And the perception is, the better you think a farm looks,
the better you think it smells.

Eco-Clothes on a Sliding Scale

There’s a new eco-friendly clothing
company on the scene that’s shaking things
up. Jessi Ziegler reports one
designer lets you pick the price you want
to pay for her clothes:

damali ayo is a designer. When she thought of eco-friendly clothes, two
things came to mind.

Ugly and Expensive.

So with her line CROW, she set out to fix both.

She designed some really fresh pieces. But that’s not the innovative part.
The thing is – she sells them on a sliding scale.

You pick the price you want to pay.

You might be thinking – there’s no way that will ever work – right?

Everyone will just pay the cheapest price they can, and the whole thing will
go under.

damali says that’s not the case.

“People will pay the highest price pretty often. And that’s exciting. And the
consumer trend is such that people want their money to go to something
that’s good, that actually benefits people.”

But CROW’s experiment is just starting out. So it’ll be a little while to see if
the idea really works.
