Is it possible to produce polarized heat waves ?.

We do know that random light waves can be polarized using existing
readily
available low cost technology.

If heat waves can be polarized then it should be possible to change
its phase
( say by 180 degree ) and then use it for wave cancellation purposes.
This could lead to an efficient cooling technique as compared to the
conventional cooling methods which has remained unchanged for the past
50 years or so.

A ' COOLER ' module can accept outside ambient heat ( solar heat for
example )
and then polarized internally. Inside the module an electrical heater
produces random heat waves which are then polarized. After which these
polarized heat waves are made ' 180 deg out of phase ' to cancel and /
or reduce ( via a mixer), the amplitude of the incoming ambient
polarized heat wave.

Similar to a conventional mixer principle used in RF and other
electronic applications. i.e: LO freq - Ambient freq = IF.
When the IF = 0, then we have total cancellation.

The COOLER module can then be used as a variable cold source for
cooling applications.
It will have no moving parts and thus its efficiency / reliability and
accuracy could be very much higher than conventional cooling systems
that are presently used using a compressor and motor etc.

The heat source within the COOLER module can be a simple electrical
heater with
accurate heating control using simple variable voltage control.. By
changing the input voltage to the heater, the amplitude of the
produced heat wave can be varied and hence the final cold source
temperature.

But the question is - Is there any method to polarize heat waves and
secondly any technique to mix heat waves.

Sure.

A Polaroid filter will reflect or absorb those nasty wrong ways.

You can't cancel energy and _a_ photon doesn't have phase. Heat is
utterly phase noisy. Phase and polarization are two different things.
Phase coherent energy is a rare thing and doesn't occur naturally.

Nope, there is no physical observation that supports what you are
thinking. The only known ways to cool is to pump or provide a cold sink.

There is no known way to destroy energy. What's an 'ambient
polarized heat wave.?

If you mean the energy, nope. If the LO and RF are the same, you produce

a dc output. If they are 180 out of phase, the energy goes into heating
the mixer and/or gets reflected. (Depends on the mixer.) You can't
cancel energy.

I a recent discussion I defended the term "radiative heat" when others
made a point for strict differentiation between heat and radiation as
very distinct things.
Seeing your confusion, they were probably right.

But even if all the heat you are interested in were in fact IR
radiation, the idea would still not work. You began by thinking of
light. So just leave the lamp in your fridge on and darken it using
your method.
As the light is neither monochrome nor has a constant phase, just how
will you generate what to achieve cancellation?

Polarization techniques are independent of frequency.
Mixing techniques are independent of frequency.

The rest of your proposal clearly violates thermodynamic fundamentals.

However, Sandia Labs is doing photonic lattice capture to approach some
of what you are suggesting.
Sonic refrigeration also approaches what you are suggesting.

There are sonic refrigeration systems that come close to what he thought
he was asking.
Properly confined cancellation of high pressure sound waves can produce
significant cooling.

But those are compressive waves, not electromagnetic ones.

What is really cute is "Magnetic Refrigeration". Details on my website
and elsewhere.
Works but seems stuck in the lab.

I'm way outside of my area of expertise, but I think you have things a
little mixed up here.

The term "heat wave" is used to describe a series of unusually hot days,
not to describe some sort of wave property of heat. There is a difference
between infrared radiation (just another part of the electromagnetic
spectrum) and the 'random' movement of molecules. People sometimes think
of infrared radiation as synonymous with heat because infrared is not
visible and it is easily absorbed causing actual heat. Also heat is often
radiated in the form of infrared radiation, but infrared only differs from
light or microwaves in wavelength and most people have no difficulty
discerning light from heat.

I've read of both. I believe they use magnetic refrigeration in
cryogenic labs. I'd have to research to be sure.

I disagree.
The basic principal behind sonic refrigeration is close
to Stirling refrigeration. The cool thing is that
compression, regeneration, and expansion along with
the required pressure-volume phase shifting are done
with essentially a single piston, (ah speaker).


I couldn't find the "sonic" refrigeration reference.
