I'm not sure how dangerous or effective this idea would be, but here it is...
I hate the heat, I climb in OK and the heat kills me at night, I can't sleep so getting up at the ass crack of dawn to go after a route is hard.
SO, I figure I could rig something up, like a copper, sealed case with like heat sink fans on it, from there a small battery powered fan blowing air accross the sinks, then a vent tube running outside the tent. NOW, place a block of dry ice in the sealed container (make sure its vented or boom), would it keep you cool ?? I'd have to vent the dry ice to the outside to keep the CO2 from smothering me in my sleep, and for the heat to go out, as the dry ice takes in the energy from the heat in the tent, it will give off co2 gas, escaping outside the tent via the tube, taking the heat with it, whatcha think???
my other idea is the human peltier, but I'll save that one for later..

I think you should move somewhere else with better weather and better climbing.

I think the investment would be really substantial to design a dry ice A/C unit.
Why dont you sleep in the car with the A/C on?

Get a hammock! Tents are hot and stuffy. Sleeping in a hammock will allow the natural breeze to cool you off. I've slept well in my hammock on 90 degree flordia nights. But I'm more acclimated to heat being from south Louisiana.
And heating tents, no need... I sleep outside on a tarp in my Western Mountaineering sleeping bag, that thing must have a heater built in it is so warm!

My record camp out was -27 below, my bag was toasty, but bein up in tent city playing cards, well it was just down right cold, so we took a wet towel and wrapped a stone from the fire ring with it, nice and toasty.

Why don't you rig some sort of water mister if you are into the cheap and cool. A fan blowing air thourgh a damp thin sheet. Is far cheaper and safer. Plus isn't it winter right now?

Although I like the science behind the idea I would have to ask; if it's that hot why you are even in a tent?
Me, I'm nekked on a blanket with a cool-one for a pillow.

So for my startup little experiment has worked well.
As far as sucking it up, I've roughed it a lot, A LOT, I'm not trying to be a man by cooking at night, so I can say, I'm rough, I'm tough. I have nothing to prove, I sleep in a tent because its HOT has hell. The reason I'm in a tent is for privacy, and the other thing, its car camping. I love primitive camping, but, when my main goal is climbing, the purpose of camping in that situation is a cheap place to stay.
Give me sub zero temps any day, 90's can kiss my ass, I'll find away around it.
The other reason is... WHY NOT? why should I be hot and not sleep... so I can say I'm tough? Ok macho man, puff up your chest, your tough, I'm a puss, whatever floats your boat.
Besides, just seeing if it can be done and work is enough reason to try.
so far so good, I found a perfect box for my little experiment, so far its not pretty but I think its going to work... effeceicny (sp) is going to be the issue if their is one, since I'm doing it up ghetto style, its mainly for a test.
So far, total investment is $68.00, damn thing better work or somethin...

Some kind of evaporative cooling system would be best. As long as it is not too humid where you are staying, it should work. You could probably find some plans if you search around. All you would really need to run it is water and electricity.
Something like this, maybe?

The only electricity would be batteries. I plan on using 12V fans to blow hot air over the fins I'm making. I may revise this thing into a radiator type version, it would be more effient. I've alreay done tests with heat and ice water. I heated in the inside to the point you could put you fingers near it and feel the heat radiating, in under a minute it was cool. I used ice water, and condensation formed on the fins in about 10 min, maybe less cause I walked away for a while.
Ice water is 32 Degree's F exactly, dry ice is -100 and change F, so I figure it should work pretty darn good when its all wrapped up.
My other issue is.. how long with the dry ice last!?

fix...
found a website with lots of good stuff on dry ice... dryiceInfo.com
according to the info they provide you need 10-20 lbs for each 24 hour period... of course this is for keeping foodstuffs cold in coolers... check out there info, lots of good tips, and kinda interesting stuff too...
good luck w/ your in-tent a/c system

Yeah, the humidity in Texas would render the evaporative cooling idea moot. You should realize one thing about your new invention. This copper box with fins on it is going to condense a hell of a lot of water out of the ambient atmosphere. So, you had best put the thing in a pan in your tent, or you will wake up sleeping in a puddle.

Heres a tip that works really well for me. Acclimatize yourself to each season. In the winter I leave my windows open. In the summer I leave my windows open. In my car, guess what? Yup, but thats cause I have no AC. It will save you a fortune in electric bills and you will be much more comfortable while doing outdoor activities in extreme temps. Mountaineers have know this for years and do it to prepare themselves for sub-zero temps during expeditions. A few years ago, I thought I would try just the opposite and subject myself to hot temps in the summer to acclimatize and it worked. Another good way to acclimitize is by excersizing in the heat. It will be hard at first but you will start noticing a difference, just suck it up. The only problem I have now is finding people to go with when its 90+ degrees outside. Anybody?

Sleep in the car, running, windows cracked (all of them) and the A/C running.
I know what you mean. I refuse to camp in the summer period. I do all my camping in the Winter when the temps are in the 20's and comfortable--believe me, when it's 20 degrees and you're in a -20 bag, it is quite comfortable.
I wouldn't mess around with stuff like that, just deal with it. Also, getting yourself off the ground is always a good idea. I use a cot in a big tent so there is airflow. That's about the best I ever could do.

90's...you think 90's are hot...try camping/climbing in AZ in the summer time...TRY 110 degrees...
Are you sleeping in a 4 season tent or something HD, try an ultra light breezy tent... a wet towel & no sleeping bag.
WHY NOT FIND AN OLD DORM STYLE REFRIGERATOR/FREEZER, GET A POWER CONVERTER, AN EXTRA CAR BATTERY FOR BACK UP, RIG UP SOME KIND OF DUCT WORK TO ZIP INTO YOUR TENT???
ok your not a pussy, just a bit soft!!!

I agree about using a cot.
I went through Air Force boot camp last summer, and we slept outside in big tents on cots on 85 degree nights. It was pretty comfortable, but any sleep is nice in boot camp.
The worst part was having to keep the sleeping bag over you keep the bugs off.
Heat, cold, rain, wind. I can deal with all that, but those Freaking Mosquitos!!
