A gallon of gasoline

The most compact, portable and convenient energy storage material ever devised by humans is gasoline.

Each gallon is equal, in work done, to the output of 400 to 500 man-hours of labor.  To get the same amount of energy from human labor

10 employees coming to work for a week, at 8 hours a day,

Gasoline and the air we breathe

A gallon of gasoline weighs about 6.1 pounds.  After you have burned that gallon of gas in an automobile engine, it still weighs 6.1 pounds.
Only energy has been removed from the gasoline. Every particle is still there, combined now with other particles, floating in the air above the highway.


This non-disappearing behavior also applies to coal, heating oil, jet fuel, fireplace logs and any other energy source that depends upon burning. If you burn 10 tons of coal, then 10 tons of coal goes into the air. It’s not coal anymore, because it has reacted with other gases, but it weighs just as much as it did before it was burned, and it stays in the air for a long time.
