The couple themselves.

Besides the typical methods such as refrigeration which uses expanding freon or amonia gas to transfer heat or standard evaporation, two other electro-mechanical methods come to mind.\n\nOne method is a thermoelectric cooler which can heat or cool based on the direction of DC electric current flow. It is built from a junction of two metals which are different and when DC current passes through the junction, heating or cooling can occur depending on the direction of the flow of the DC current. This is known as the Peltier effect.\n\nThe second totally mechanical method is known as a Vortex seperator. Air is introduced at high speed into a tube with a curving vane inside. As the air spins up through the tube, the colder air, which is heavier is forced outside due to centrifical force while the air moving up the center is warmer and lighter than the cold air. The difference in the weights of the cold and warm air cause them to seperate from each other with the cold air unable to make the tight turns and is forced to the outside of the tube as it spins to the top. These units typically have a cold air output connection on the outside of the tube at the end and a warm air connection in the center of the tube at the end.

The classic experiment (18th century) was to feed a mouse kept in a sort of thermal bottle that contained some ice at a known temperature under it, measuring the additional ice melt caused by the long term presence of the mouse.\n\nAnother way to do likewise would be to:\n- keep one or more mice in a thermally insulated container (say, small terrarium fully insulated w/ styrofoam)\n- with air flowing through it at a known rate (say, fans into a main, air through a calibrated delta-P engpass)\n- two thermocouples at intake and outtake\n- a recorder integrating the temperature delta times air flow over time, giving the thermal energy output\n- supply water at the same temperature as the air intake\n- subtract the missing water's latent heat (specific latent heat x evaporative loss of water, counting water input, dejections etc.).\n\nPiece of cake!\n\nEasier yet, do ANY kind of scientific measurement, throw away all the data, publish made up data you think you may have been reading into the Holy Bible, or you believe God told you directly.\n\nThis is how the White House does science these days, and if it is so, then God wants that, and it must therefore be right.\n\nIf you disagree, you are a kneejerk liberal, or a terrorist, you are a security risk, you can be spied upon, and if you are of middle eastern origin you can be flown to other authoritarian countries to be tortured.\n\nSo be very careful.

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who developed many devices which greatly influenced life in the 20th century. Dubbed "The Wizard of Menlo Park" by a newspaper reporter, he was one of the first inventors to apply the principles of mass production to the process of invention, and can therefore be credited with the creation of the first industrial research laboratory. Some of the inventions credited to him were not completely original, but alterations of earlier patents (most famously the light bulb), or were actually the work of his numerous employees. Nevertheless, Edison is considered one of the most prolific inventors in history, holding 1,097 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany.

Antarctica--in particular, the Russian station Vostok, at which a record-      setting low temperature of one hundred and twenty-eight point six below zero      Fahrenheit was recorded in nineteen eighty-three. \n\n In nineteen-o-eight the university of Leiden      made history by producing the first super-cooled helium. Guess how cold liquid      helium is? \nFour hundred fifty-two degrees below zero Fahrenheit.\nhttp://amos.indiana.edu/library/scripts/coldworld.html

"In 1926, Einstein and former student Leó Szilárd co-invented the Einstein refrigerator. On November 11, 1930, U.S. Patent 1,781,541 was awarded to Albert Einstein and Leó Szilárd for the refrigerator. The patent covered a thermodynamic refrigeration cycle providing cooling with no moving parts, at a constant pressure, with only heat as an input. The refrigeration cycle used ammonia, butane, and water."\n\nFrom Wikipedia, http://en.wikipedia.org/wiki/Einstein\n\nHope this helps!

Neither. They are both just a couple hussies. The media (mags, news, etc.) has told us they are hot. HUH, is plastic hot, are brainless bimbo's hot... I think not...

whoissarthak's idea works, but that isn't a wet suit; that's a dry suit.  A wet suit works differently.  The idea is that there are basically three ways to move heat: conduction, radiation, and convection.  Conduction is when two things are in direct contact, like touching a hot stove or a cold flagpole.  Radiation has to do with the infrared light emited by warm bodies, and has nothing much to do with your project.  Convection is the real concern--it is the transfer of heat by means of a fluid intermediate, and it is the fast form of heat loss.\n\nYou're body sheds heat by means of perspiration, where sweat evaporates and takes heat away with it--that's convection.  When you fell colder in a strong breexe, that's convection taking heat away quicker.  When you blow on a spoon of hot soup to cool it, that's convection.\n\nThe way a wetsuit works is by not allowing the water in contact with the skin to be carried away.  It inhibits the movement of water through it.  Enough gets in to contact the skin and make your skin wet, which is why they call it a wetsuit, but that water doesn't leave easily.  It stays put and your body heats up the water.  Hence, the water in your wetsuit is much warmer than the water in the surrounding ocean, so the water taking heat from your skin is not quickly carried away and replaced by more cold water.\n\nIf you want to make a wetsuit, you want something htat will make it difficult (but not impossible) for water to come and go.
