Since the season seems to have turned to PMM discussions, which is
really a quest for the free energy endowed to us by Mother Nature,
I propose the following air conditioner and water heater (the former
is the most useful feature of the device in Arizona) for net-think.

Construct a vessel of two ellipsoids with different diameters and
common focal points.  Combine half of each ellipsoid with a spherical
surface which has one of the focii as a center.  After carefully
soldering and polishing the interior so the walls reflect radiation
'perfectly', you have a device with a cross section that looks like...

My apologies for the graphics.  Now, mount a small bulb at each focus
so that a fluid (e.g. freon, water, etc) can flow to and from the bulb
thru small pipes which enter thru the walls.  In the following, we can
ignore 1) the non-perfection of the interior surface and 2) abberation
due to the fluid pipes.  These become negligible by building larger
and larger vessels.  (The one I use is 69 cm end to end, made of spun
and polished aluminum 6064 sheet, with copper bulbs and pipes :-)

Now, the geometry of an ellipsoid will focus all radiation from focus
f1 onto f2; all rays from f1 meet an ellipsoidal surface and are thus
sent to f2.  However, not all radiation from focus f2 is focused onto
f1; the fraction which meets the spherical surface is returned to f2.

So, as time goes by (another assumption, albeit a persistent one), the
bulb at focus f2 will receive more radiation than the bulb at focus f1.
This is immediatelly put to work to heat water.  And, the bulb at f1
looses energy since it does not have a balance of radiation emitted
versus received.  We compensate for this by heating the bulb from our
living room air.  Evacuating the vessel will increase efficiency.

Now, as we sip our hot tea and take in a cool breeze wafting our way
for free, can someone devise why this device works (or doesn't it?).

(:-) Larger commercial versions could generate electricity, aluminum,
conundrums, etc.  One can add a mechanism to defocus the device to
reduce the energy flow, lest it melt down and/or freeze up (:-(.
