Reefer power

On many cruising boats the biggest power hog is the reefer.

Dead batts are common along with a variety of charge systems.

FIBER OPTIC CABLE ,for POWER?

I do love the propane fridge as it is cheap to operate and silent.

If our USA buroRat masters allowed we could simply run reefers and cook stoves and lights on acetylene as its lighter than air so no danger.

Heat is what makes a propane fridge operate ,

I have been wondering if a mirror setup that would track the sun could deliver enough heat down a fiber optic cable to power a unit?

With little mass a solar capture mirror should be lots less juice to keep aimed at the sun than operating a compressor.

How do we get the energy to where its needed?

Eutetic fluid could easily hold overnight freezer temps.

Any ideas???

I tried to create an acetylene generator , as was frequently done in apartment buildings at the start of the 20 century , but the problems of variable output and explosion was a stopper.

But the thought of cooking and cold beer from a can of rocks was attractive.

 

Just as an idea, you could also make a portable refrigeration kit which uses the night sky radiation for cooling the eutectic plates during clear nights.

The core part of the system is a parabolic reflector, which can be bought online:

or home-made:

Just as it can focus the sun rays into the focal point during daylight, a parabolic reflector (or mirror) can dissipate heat from the objects placed into the focal point during clear nights. The deep-space background temperature is -270°C, but the Earth atmosphere shields us from this ultra-freezing cold, so the so-called black-body temperature of a clear sky in a mild-climate regions is approxim. -10°C at the sea level.

Basically, whatever you place at the focal point of a parabolic mirror exchanges the radiant heat with the sky, and can easily be cooled down to below 0°C. So you can cool your can of beer by putting in the focus of a parabolic mirror for free and with no mechanical or electrical parts involved.

Incidentally, the next step in this direction might be what guys at Stanford University are doing:
