How To Build a Solar Generator
Affordable solar power using auto parts could make this electricity source far more available.

Interesting ideas. Wish for more detail but that seems the norm.
Update — Steve mentioned the auto tracker thing in a comment on this post and rather than bury this info in a comment here it is…
The easiest auto tracker I know of is a power steering assist cylinder with 2 12 oz freon cans attached on either side of a metal plate and attached to the hub of the device needing to follow the sun.
The cylinder is hooked to the control arm of the device and each side charged to balance the unit with both cans covered.
Each can is attached to one of the lines on the cylinder so that when one is in the sun the pressure is higher than the one in the shade and the unit moves to keep them both equally shaded/in the sun.
Quite elegant actually. One moving part and that is the piston.
Any low boiling temp gas should work as long as it doesn’t eat the rubber in the seals or lines. Propane should be safe and is easier and cheaper than freon r 12 to obtain and nowhere near as bad for the ozone, just highly flammable. Will have to try it and see.
