ok remember that freon or r134 are used in AC but is not like it is a substance that stays cold... you to compress it in order to make it liquid and then it absorves heat and evaporates completing the cycle... if you are looking for a sort of system that will make something stay cool.. .hmmm man it is called Air Conditioned

Allergic to the cold???  Well there are quite a few options.  There is a lot of gear out there at the moment that helps ease the cold.  There are thermals, formally known as Long Johns.  Thermals are made out of Polypropylene.  They're not very bulky, you can wear them under clothing and they also come in cool designs if you want to show them off.  They are used a lot in cold places and/or used when camping. They are very useful.  If that doesn't sound good, there are so many options out there, you just need to look.  Try a camping place, they have a lot of clothing designed to keep you warm.  The other option is to go and buy a jacket and a heater.  Down(duck feathers) is also very good at keeping you warm.  Try buying a down blanket. So warm

dunk a towel in water....wring it out good....roll it into a tube a stick it in the freezer...it will freeze pretty quick as the fabric allows air to get in. drape this across the back of your neck...your body temp will drop pretty quick\n\nyour kinda cute by the way *wink*

Does it have to be a material? the best solution for this would be to have 2 cans one just inside the other with a compleat vacume between them, as there is no air to transmit the heat between them the liquid inside wont change tempreture.\n\nthis is the principle of a thermos flask,\n\nif you need an actual material, somthing that would trap air to stop it from moving and spreading the heat such as glass fiber like you might have in your loft\n\nhope this helps

Enclose your entire house in weather wrap. That should keep the weather away.

Get a couple of fans and make a "wind tunnel" effect, to move air thru your room, and not just push it around.  By pulling air from another room, you should be able to cool down yours.\n\nI found that putting a bowl (metal works best) of ice in front of a fan will cool things down until the ice melts.

hey hey. finally something i know about.\n\nInsulation? by that i think you refer to the resistance on heat traveling from one area of a building to another (or from outside to inside)? well, i have heard of, fibreglass woll. spun molten rock wool, polystyrene, etc. if you are refering to building materials used by varying cultures around the world, then i would say, mud walls. clay walls, logs, stone, thatch (roofing), straw (hay), ice (igloos). If im not on the right track, im me and ill tell you other stuff

Put on more clothes and stay warm. Or turn up the heat.

There are plenty of things you can do...wine coolers, picture frames, candy, chocolate, cd's of fav songs, candles, disposable cameras, even those can coolers things to keep your drink cold.  try theknot.com for ideas

plastic, but it doesn't breathe, so for a person or something, wool is good.\n\nAs for insulating something that is not a person, combinations work well, and so does aluminum foil.

don't buy anything with goose down, if it gets wet, you get cold and miserable. go with a good synthetic, like thinsulate, goretex, or even a light weight wool.

Somehow show that not everything needs to be frozen, as it would be if you just stored it outside. And that a "balmy" 38 degrees or so (whatever you set a fridge to) is desirable.

besides the obvious from above answers, you need the following design specs....\n\na ship that is air tight,\na ship that will protect the occupants from radiation,\na ship that is able to withstand extreme cold & heat,\na ship that is structurally strong from pressure

I don't think I like your work!  Why on Earth can't you wear a shirt under their garb? If you have a desk job, bring in a small heater and make a copy of the logo and stick it on there with tape.  Then crank up the heat till you are warm and can do your job without thinking about how cold you are.

Ice and Heat.\nI'm the exact same way. During the day when im just relaxing I put bags of ice on them, and at night there are heat wraps that I put on them. It works great.
