Curious, I rang our largest commercial producer, Angas Park Fruit
Company, in the Barossa Valley.  I was assured that all of their
products - stone fruit, apples, grapes, sultanas - are still sun-dried
in racks after sulphuring.  Exactly the same method my father used when
I was a boy.  The woman I spoke to said that sometimes sheets of
plastic were placed over the drying fruit to caramelise the sugars and
darken it.  The only users of artificial heat she knew of were in
Queensland, where hot air is used for drying mango slices.

This complicated wit-play started off with Dave running power stations
on ?-dried chicken poop.  That being an industrial scale of drying
would perforce have used some, or a lot of the energy from the power
output to pre-dry the fuel.  Alternatively, as you point out, solar
pre-drying would require a large area exposured to the sun.  My humble
suggestion was that the anaerobic digestion of animal and human faeces
in closed tanks to produce methane and fertiliser was a preferable way
of dealing with a pollutant, reducing green-house gases (methane has
about 20 times the green-house effect as CO2), and providing energy.

By all means!
