Ok, show and tell!

Richard, it will take one *hell* of a lot of ice. Dry ice would be
better than water ice but I know the water numbers off hand
9 btu to melt one pound of ice, another 31 btu goin up to 60, so use
40btu per pound.

That 5000 BTU ac running 5 hours is 25000 total btu
25000/40 is 600 lbs. I won't look it up but dry ice might be 6 times
better or 100 lbs. for five hours. Do the math to get better that an
approximation but you can see you'd literally need a ton of dry ice to
do the weekend.

maybe buy ten batteries.

I just looked it up. Dry ice packs more punch than i thought 250 BTU
per pound. or twenty pounds an hour to equal that 5000 BTU ac. You'd
only need 1000 lbs. to do the weekend.
