Please log in for more thread options Just how can microwaves be used to cool something? Usually they heat things up. http://www.sciencedaily.com/releases/2007/09/070914105600.htm Thanks, Radium | |||||||||||||||||||||||||||||||||||||

| Hi: | | Just how can microwaves be used to cool something? Usually they heat | things up. | | http://www.sciencedaily.com/releases/2007/09/070914105600.htm | | | Thanks, | | Radium Just how can friction be used to stop a car? Usually it heats up the brakes. Heat is the kinetic energy of motion of the molecules. If you use a microwave to stop a molecule then you've "cooled" the molecule. | |||||||||||||||||||||||||||||||||||||

So hydraulics on a fridge is the next step in economic and engineering progress? Should be useful when moving too. What plagued the researchers at Los Alamos when working on the idea of a super bomb is that the heat generated would build up enough to ignite the atmosphere. It turned out the energy was transformed to radiation that could rapidly dissipate. Something of this ilk must be happening here. Just as passing electricity through (I forget which salts) certain crystals could drop temperature to near zero. The crystals changed state or something. No doubt someone clever will put in an appearance to reveal how its done, soon. | |||||||||||||||||||||||||||||||||||||

If you want to call the motion of fluid/gas in a fridge pipe "hydraulics" then that step has already been taken, you are too late. | Should be useful when moving too. | | What plagued the researchers at Los Alamos when working on the idea of | a super bomb is that the heat generated would build up enough to | ignite the atmosphere. Not at all. It plagued the popular press who love to promote doom and gloom to create newspaper and magazine sales, the researchers just carried on, ignoring them. That kind of idiocy is still with us today with the LHC. I shall ignore you, too. *plonk* | |||||||||||||||||||||||||||||||||||||
