W: Hi, Judy, mind if I sit down?
M: Not at all, Steven. How have you been?
W: Good. But I’m surprised to see you on the city bus. Your car is in the shop?
M: No. I’ve just been thinking a lot about the environment lately. The air will be a lot cleaner if we all use public transportation when we could.
W: I’m sure you are right. Though a diesel bus isn’t exactly pollution free.
M: True. But they’ll be running a lot cleaner soon. We were just talking about that in my environmental class.
W: What is the city going to do? Install pollution filters of some sort in all their buses?
M: They could, but those filters make the engines work harder and really cut down on the fuel efficiency. Instead they found a way to make the engines more efficient.
W: How?
M: Well, there is a material called conium oxide. It’s a really good insulator. And a thin coat of it get sprayed on the certain part of the engine.
W: An insulator?
M: Yeah. Actually what it does is reflect back the heat of burning fuel. So the fuel will burn much hotter and burn up more completely.
W: So a lot less unburned fuel comes out to pollute the air, right?
M: Yeah, and the bus will need less fuel. So with the savings on fuel cost, they say this will all pay for itself in just 6 months.
W: Sounds like people should all go out and get some of this stuff to spray their car engines.
M: Well, it’s not really that easy. You see, normally, the materials are fine powder. To melt it so you can spray a coat of it on the engine parts, you first have to heat it over 10,000 degrees and then, well, you get the idea.
It’s not something you or I will be able to do ourselves.
