It seems to me that one of the best and cheapest uses for solar
thermal would be for trough style collectors to raise the temp of a
container of sea water for a passive solar still that operates slowly
but continously to water crops. No moving parts and extremely low
cost. I may try this, I'll make it out of Aluminum flashing.

Google "aluminium salt water" for good reasons not to use aluminium
(although if you are just doing this short term as an experiment you'll
probably be fine)

Eh? Please tell more about your trough style collector with no moving
parts - I have a special fondness for minimizing the number of moving
parts in a design...

That proves my point.
