The Geek's Raven
[An excerpt, with thanks to Marcus Bales]

Once upon a midnight dreary,
fingers cramped and vision bleary,
System manuals piled high and wasted paper on the floor,
Longing for the warmth of bedsheets,
Still I sat there, doing spreadsheets:
Having reached the bottom line,
I took a floppy from the drawer.
Typing with a steady hand, I then invoked the SAVE command
But got instead a reprimand: it read "Abort, Retry, Ignore".

Why isn't gunpowder used as an energy and power source?

Gunpowder is incredibly inexpensive -- anyone can buy gunpowder for 35 cents a pound, and probably produce it on their own, for rather less. It's also an incredibly efficient source of energy -- a kilogram of gunpowder produces 3 million Joules of energy. That's almost 5000 horsepower. So, why isn't gunpowder ever used as a practical source of energy or power, other than for purely destructive purposes? Why isn't it used to heat homes, to power transportation systems, to send rockets into space?
