keeping cool in the sun
|
When working in the garden, it can get pretty hot, so I made the wife a solar face cooler that runs 2 small CPU fans. Works well in full sun, and is very light weight.
Not being the type that is easily satisfied, I got a bit carried away with my mega solar hat. The panel on top has a self powered X/Y tracker, with slip ring power output, and also has a hatband made from rechargeable NIMH cells set up as a 12V string. The panels around the brim are two parallel strings, so no mater which way you are facing the cells can charge. A bit on the top heavy side for every day use, but it is a great way to get people to come over to our alt energy displays at green events.
