FYI Eutectic Autofridge (keeps cold)

Not what we were looking for, but found advertised second hand for private sale a Eutectic Autofridge.

Extract from website quirks.com.au -

The AUTOFRIDGE comprises a compressor driven system combined with the power-saving advantages of the eutectic refrigeration system - the 'eutectics' act as a cold storage compound for the refrigeration contents. The eutectic fluid surrounds the outside of the four walls of the interior cabinet acting as an 'ice bank', and, in an ambient temperature of up to 32 degrees Celsius, having initially pre-chilled the AUTOFRIDGE, it need only be run on its maximum setting for a total of 5-6 hours per day (preferably 2 hours in the morning and
~3 hours in the afternoon), and during this run-time, the fluid is frozen and the cabinet contents are thoroughly chilled. The AUTOFRIDGE can be turned OFF in between the run-times, and the eutectic fluid acts as a thermal phase change (cold storage) compound and provides the continuous refrigeration hold-over for NIL power consumption. Figures quoted assume normal usage of your refrigerator, e.g. opening/shutting the lid to use or replace contents.

Just in case anyone is interested and hasn't heard of this type of fridge. Would be good for people like us who keep the fridge in the car and turn it off at night when the car is not running.
