Home Forums General Discussion Keeping cool off-grid Re: Keeping cool off-grid


While reviewing some reports on industrial solar furnaces that melt steel I saw a video from Japan where an experimenter had adapted a satellite dish reflector with small mirrors. It occurred to me this would lend itself to driving a gas fridge to produce cool air. Only electricity needed would be for fan to blow cool air through the duct system.

Such a solar furnace would also be useful to metal smith needing heat for heating metal to be worked, melted or just re-forged.

Adding mirrors to a scrapped sat dish would be a low cost experiment.
