yeh the compressor fridges are more efficient, but peltiers work too
and are solid state so you can leave them on for years and run at
different amps, no maintenance.

I wouldn't' be able to use gas if I sealed the shed up.  this will
just be a weekender once I've setup the water tank I can move on..

Easier to get a caravan or build a full house for something permanent
than do up a shed.  But water, power, resources, etc. are good to have
on stand by.

I boarded off the gaps between the concrete slab and walls so no
spiders crawl in anymore
