Open source tracking solar concentrator is go.
For nearly two years now I've been developing the prototype for a solar energy device makeable from scrap and recycled materials, using very basic tools and skills.
It's now working, details available here:
Facebook group here.
This has been possible largely due to the awesome help and support I received through this site.
Currently I'm back in New Zealand, preparing the first free workshop on the device's construction and use, taking place the three weekends after Easter at the Tui community, Golden Bay. Then back to Europe for the summer and tour this thing around.
Animated tutorials will be available at www.solarflower.org as soon as I find a spare second to do them and finish the website.
My God I'm busy.
