" fired this volley in news:c5ef16f3-
:

The figures I think are wrong are Karl's 9 btu to melt a lb. of ice.
The numbers I learned in high school were 144 btu's per lb of ice.

Karl is no dummy. But he must be thinking of something else.


And you're right.

The "ton" is confusing, too. Most people think the 12K BTU is the amount
of energy necessary to melt a ton of ice -- not so, it's the amount of
energy PER HOUR to melt one ton in 24 hours.

So the total energy required would be 288,000 BTU, and of course, one
two-thousanth of that would be 144 BTU.
