Anybody know about sun tracking devices?
(antioch, CA US)
I never built a solar cooker , but I assume that everyone has to move or adjust the solar cooker manually to align it toward the sun every 15 minutes or so. I have yet to see anybody coming up with an automatic sun tracking device that can do the job for you. Telescopes use tracking devices to keep telescopes trained toward same spot in the sky all night . or you know, we have solar tower with scores of heliostats (mirrors with tracking device behind each) bouncing sunlight toward the top of the solar tower concentrating heat to genereate steam for electricity generation. I guess there is no inexpensive sun tracking devices made available that can guide our solar cookers... They are expensive becaue they are heavier.. Where is the light duty variety, anybody??
If it is crank powered, I will take it.. though.
Where are the lightweight, cost effective solar tracking devices for sale to the public?
We have been searching for a commercially avialable solar tracker as well, but we have not found an inexpensive one yet.
There are some available but they are a bit pricey.
If there is someone who knows of the whereabouts of such a device we would also like to know about it. We could use a little guidance as well.
