Alan,
I was out on a bike trail earlier when I read your message on a
BlackBerry. Now that I've sat down and read it on "the big screen," I
see I missed your point.
You were speaking of chilling the H2O ice down to -100 Celsius (-146
Fahrenheit) before placing it into the sub, not
placing the dry ice into the sub. Great idea! That would
significantly increase the cooling capacity of a given volume of ice and
probably lessen the water vapor released into the hull (from the air blowing
over the melting ice) as well.
I had originally meant it as a facetious comment. Thanks for turning
it into something useful.
Cheers,
Jim

Hi Jim,
Dry ice has a temperature of - 100 Celsius.
your average home freezer is about -17.
If you stored your ice in a container with the dry ice you could
get it's temperature down a lot lower than -17 & make it more
efficient for
cooling. ( In theory ).

A bit of tongue-in-cheek there, Jens? I guess dry ice is out for
cooling, too. Hmm...

What about using oxygen candles that burns real
hot...
