Can you explain a bit more clearly? |
|
| |
Is this like laser / optical cooling? |
|
| |
I don't quite understand what the category "product:refrigerator: microwave" is supposed to suggest. How is anything in here not magic? |
|
| |
People will come up with suggestions for X where X : microwave = cold : heat, no matter what. This is the category those suggestions go into. It's not clear to me that it's completely impossible to use energy to quickly convert the movement of molecules to some sort of radiation - although the attempts so far have certainly fallen short of physical plausibility. |
|
| |
its based on the idea of inductance. And a hope that there is a wave form that water (or maybe a particular material...say to be used as the dish) will attempt to resist. |
|
| |
The stinging point is that vibrational energies and its mechanism of releasing energy (black body radiation) is a radiant force (ie goes outwards...unlike magnetism which allows feed back). |
|
| |
Theoretically if you could amplify the black body radiation flux (externally and without putting more energy into the system) put out by an object...and have it contained in a vessel that had minimal black body radiation (very cold walls?), then this could work |

"My god!, it's filled with stars!" |
|
| |
why not a sonic microwave oven? |
|
| |
ultra high frequency sound forces the atoms to vibrate at lower frequencies, thus cooling. |
|
| |
i know theres a flaw here somewhere.... |
|
| |
truth be told the idea itself went far over my head...but this concept of flash cooling seems very good. i wish i better understood why the working of a refrigerator could not somehow be 'sped up' to a microwave oven time scale.. |
|
| |
a microwave works because the dipolar molecules (water in particular) attempt to align themselves with the alternating electric field. |
|
| |
So, if you could generate a static electric field that could permeate the mass to be cooled then this should reduce the vibrations that occur in the water? |
|
| |
electric fields are much more prone to attenuation through space if i remember correctly |
|
| |
hmmm, if vibration is transferred back to the spin of the molecule (which does happen some how/times) this will resist the electric field so the field generator will have to do more work to correct it...that work could generate heat and that heat can be expelled from the chamber |
|

This is the bit that should be in the idea. Much more clear than the bondflexing mess. And so simple that you'd think they'd have figured it out by now if it were true? |
|
| |
Seems to me this would only put the brakes on any continued heating rather than actually cooling the food. |
