Using a Stirling Engine to power an arduino

I was just looking at one of these engines too on ebay.  I was thinking more for using sunlight, but this is still pretty neat. Ethanol-Powered Arduinos

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/

Make your own cheap Parabolic Mirrors

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

Nice solar light jar build

Nice build, I don’t know if I would glue the light in since I like being able to take it apart, but I do like the use of cheap hose clamps to hold the jar to a post. http://www.instructables.com/id/Jar-Solar-Lights-That-Wont-Fill-Up-With-Water-and-/

Interesting tech from Xerox, print out solar cells

This sounds cool, Xerox PARC has a method to print out solar cells.  This could come in handy with printed circuits (giving them a power source).  I wonder if anything will become of this. https://www.technologyreview.com/s/601097/a-xerox-machine-for-super-solar-panels/

Nice idea to teach kids about solar energy (Thermal)

Nice idea, the students build some simple solar thermal heaters, and record the results of heating up water. http://www.instructables.com/id/Kids-Solar-Water-Heater/
