Free Cool — My solar powered AC quest
This is a look at my quest to build a portable solar powered way to get cool on a hot day. It is a move from the “toy” stage to a serious usable device —–powered by free energy. A solar powered fan is very easy but a small homemade real solar powered AC is more difficult. Making the cold is the hard part. I decided to buy a small ac/dc freezer to do that part of the job.
