Re: A few things to ponder...
Awhile back ago after the hurricanes hit us in 2004 and I was sitting in my patrol car for the only air conditioning available I had the notion to build a homemade battery operated system for a small room that ran only on D cells, charger pack or solar cells. At first, it was just a battery operated fan with the copper tubing wrapped around it and a small fish pump that was battery operated that siphoned ice water from a cheap small cooler.
Then the project got bigger. I found a small radiator and used the same principles in mind and then although efficient, it drained the batteries faster so I improvised with solar cells. This kept up quite well during the storms that knocked out our power for a day or so. Then I started thinking of a way to maximize ancient evaporative cooling versus conducted cooling within a 6 man tent for those days where it got a bit warmer...
Then both of the ideas came into play. I got the battery operated fan to mount on the top of the tent to blow downwards with the sump cooler but the whole operation is solar powered and continuously charged by the battery cells that I've maintained during the day. With a little help of an engineer, we strapped on a small thermostat so we can maintain a certain temperature during the night. Plus I collected about five emergency blankets and had an insulated cover built for the tent. It's kind of like those solar windshield protector things...it's about the same depth. I have to admit, for a shoe string budget and some creative thinking, one can make some pretty neat stuff for austere conditions.
The greatest thing is that the solar cells and charger that I use for this AC unit can also be integrated into powering up many other things in the field. From laptops, wi-fi extenders, players of all types...the next thing I'd like to build with the FJ in mind is a mount to reuse an old satellite dish as the ultimate wi-fi extender out in the field. If I could get it to rotate, it would look like an old school radar and a legit target of opportunity from the air.
