    whilst compressor fridges have been around for a long time they do use quite large amounts of solar power that is not available in the winter. A conventional fridge uses power on standby.
    Dr Tom Chalko, whilst looking to overcome the problems came up with the chest fridge which only uses power for about 90 seconds an hour. his remarkable design is shown below and could serve as a blueprint for self builders.

    just goes to show there are some clever people about.
    Whilst chatting to Happyhippy, Rob mentioned a thermo generator that will charge his batteries by utilising the heat difference between two surfaces and a system developed for use on a wood burning stove. He has seen it working and has ordered one.

    The effect is a well known and brilliant for those dull winter days when your solar panel does not cut it. As long as you have a heat source i.e. a wood burner or even a paraffin lamp then you can continue to charge your batteries without being constrained by daylight hours.

    When I fitted out my boat I used a compresor kit and made is top loading, the insulation was 5 inches thick and was very economical on power use, I am supprised that the caravan/motorhome world has never gone down this path.

    On the back of that vid, I have just ordered an arger for the van

    Nice chap said it would be no problem to fit and assured me it only ways a few lbs

    Well given the fact I will be able to ditch the leisure batteries and the solar panels, I thought, why not !!

    Here is the one I am having installed...
