Interesting build,  It cycles cold thru the bottom, which gets heated up and then “steam” out side. https://www.instructables.com/id/How-to-Make-Solar-Water-Heater/

Simple Solar water heater

Nice build overall.  Not so sure I would use plywood for the backing in the elements.  Could be a good away to heat small pools.  I like the use of flashing for the backing. http://www.instructables.com/id/DIY-Solar-Water-Heater-Deluxe-Aluminum-Backed-COPP/

Another solar heater way to generate electricity

Have a magnify glass focus on one side of a peltier, the have that in water to cool the other side to generate electricity.  Interesting idea overall. https://www.instructables.com/id/Generate-Electricity-From-Nothing/

This is one big Solar Pop Can heater.

OK like wow that’s allot of soda cans.  It sounds like the build does a good job heating things up with the sun.   Not so sure I could get something this big by my family for a build. https://www.freeonplate.com/how-to-build-diy-solar-panels-out-of-pop-cans/

Interesting solar thermal heater build

A more advanced solar tracker

This build uses a RPi to track and position panels for the sun.  Its a nice build.  Cheap too if you can source the servos yourself. http://www.instructables.com/id/52kW-Solar-Tracker-Controlled-by-Raspberry-Pi/

Stumbled on this on hack a day,  The first mirror is easier to make, but …it depends on air pressure (lack off) to keep its shape and could leak out.  The second one is a bit more involved in building, … Continue reading
