1 gram of nickel would be equivalent to about one barrel of oil

Stated another way, assuming a 42 gallon barrel of oil yields 33 gallons of gasoline, one ounce of nickel would yield the energy equivalent of 33 gallons of gasoline. Awesome if true.

I made a mistake .... make that 924 gallons of gasoline.

1 oz. = 28 gm. or equal to appx. 1000 gal. of gasoline.
