Run off

Hi teachers,

Please help me with the excerpts from Newsweek. Thanks.

US military headquarters in Baghdad used generators that run off food waste, shredded documents and ammunition wrappers.

1. What is "run off" here?

2. Does it mean eloping as in "Mary is running off with his boyfriend"?

3. Would "A thief getting out of the store, is running off with $500 cash in him" be correct?

Thanks

These are two separate idioms. Sometimes we hear, "It runs off of X," which is even lower register. The question is, what is the fuel, or source of power?

"To run," in this case, would refer to some kind of motor or engine.

"It runs by burning alcohol" equals "It runs off alcohol."

Hi Avangi,

1. Do you mean the military used generators with the source of energy coming from burning / processing food waste, shredded documents and ammunition wrappers?

2. The preceding sentence to it is "Pentagon is getting its green on". Dose that mean Pentagon is introducing green into the military?

Thank you.

As long as you understand that "green" in that usage means "environmentally friendly operations."

Hi teachers,

"US military headquarters in Baghdad used generators that run off food waste, shredded documents and ammunition wrappers."

> Could I know if "run off" has the same meaning as "run on"? When is "run on" used and not "run off"?

Thank you very much.

Regards,

Tinanam
