paulecia Posted May 28, 2008 Report Share Posted May 28, 2008 Hello, I am an industrial designer and I am searching for a material that will store heat when put in the microwave and will not cool down very fast.I am working on an alternative to the hot water bottle and for the moment I have been told the wheat can work. Any better ideas?ThanksPaula Quote Link to comment Share on other sites More sharing options...
modest Posted May 29, 2008 Report Share Posted May 29, 2008 edit// deleted previous posted (stupid) idea. Can I ask, is this a thermos - to keep something hot, yes? A microwave safe thermos? -modest Quote Link to comment Share on other sites More sharing options...
alexander Posted May 29, 2008 Report Share Posted May 29, 2008 this should work with some salts... I know they are using salts in a 30 Mw power plant in brazil or something to that extent. it uses mirrors to concentrate sunlight on a tower, top of which has capilaries with water that will produce steam to power the turbine, but their new 30Mw power station will have the top made of some salt that retains heat rather well.... i dont know if it would heat up in a microwave, though i doubt that it wont, then all you need is 2 conainers, some salt in the middle, close it all off, and shazaam, you got a microwaverable hot water bottle that will remain hot for hours or something like that :eek: Quote Link to comment Share on other sites More sharing options...
freeztar Posted May 30, 2008 Report Share Posted May 30, 2008 What Alex is referring to is a solar power tower. They use sodium for it's heat retention abilities. Quote Link to comment Share on other sites More sharing options...
alexander Posted May 30, 2008 Report Share Posted May 30, 2008 thank you, freez :hihi: i briefly saw a think about it on the science channel, it sound rather interesting... Quote Link to comment Share on other sites More sharing options...
paulecia Posted May 30, 2008 Author Report Share Posted May 30, 2008 Yes you can ask and no it is not a thermos, it is a "cozier" alternative to hot water bottles, some kind of pillow that would be covered with textile, kind of pillow, so could these two container be made of a flexible material?

paulecia Posted May 30, 2008 Author Report Share Posted May 30, 2008 About the salts and the container...could this be oridanry cooking salt or do I need something special? And where could I get it? Quote Link to comment Share on other sites More sharing options...

Sodium is kind of hard to come by and is quite expensive for your intended use. Plus, it is extremely volatile and can spontaneously ignite in the presence of Oxygen. I'm not sure if salt would work. I do know that salt water will cool faster than fresh water. :hihi: Quote Link to comment Share on other sites More sharing options...
