W: Oh, hi, Tom. You weren’t in engineering class today, were you?
M: I have the flu. I was wondering if you could tell me what went on.
W: Actually we had an interesting class. [7]Dr. Collin talked about a new type of fuel.
M: Oh. yeah?
W: Uh-hum. It’s called dimethyl-ether or DME.
M: Oh. I remember reading something about DME. It’s mostly used in spray cans, right?
W: Right. DME doesn’t destroy the ozone. so it’s been environmentally friendly.
M: But doesn’t DME pollute the air if it’s burned in an engine?
W: Dr. Collin said something about its exhausts being clear, that [8]it doesn’t release as much pollutants as diesel fuel. And he mentioned something about DME being more efficient than other alternative fuels.
