Dermot Westcott reccomends adding a solar panel to trickle charge the
battery powering Cliff Golden's thermoelectric cooler that holds the
food/medicine/whatever that absolutely must be taken camping and cooled.
The cooler costs about $100, a 150 amp-hr deep-draw battery is $110 on sale
(in Indianapolis in 1993), and a photocell array with assorted electronics
necessary to control the charging process (don't want to overcharge!)
shouldn't run more than $350 VWG (very wild guess). So far we've spent
$560, and after adding odds and ends to hold everything up, point the solar
cell array, etc., the total cost shouldn't run more than $600. Am I
forgetting anything? Hate to bring this estimate in on the low side. Given
the proliferation of hardware this setup is only going to be suitable for
sites that you can back your half ton truck up to. (Should we cost the
Seriously, if refrigeration is necessary, there are several alternatives to
an electric cooler powered from a gas powered alternator. I like Cliff's
thermoelectric cooler idea the best, but I think that it is only suitable
for relatively short term usage, say a long weekend, where a large battery
can be used to power it for the entire stay. The propane powered
refrigerator has the advantage of a compact power source that is readily
renewable (not in the cosmic sense) at your nearest propane retailer.
Any more ideas?
