Re: [papercreters] solar collectors

Someone marketed an inflatable reflector years ago, with clear front and mirrored back, but I haven't seen one lately. I think if I had an inflatable reflector I might just leave it as is. It would be great for those wilderness camping trips. I do have a couple of mylar space blankets that could be made into a balloon. Maybe I could seal the edges with Gorilla tape.

Another nice design I saw was based on a round container of mercury that was rotated. The mercury flowed into a parabolic shape with focus determined by rpm, and made a great reflector. Too bad it was extremely toxic.

It got down to the mid 50's here a couple of weeks ago. I put on long pants and a hoodie.

If you have time and want to do a big one tape some Mylar to a hoop, shiny side in, add another layer of any kind plastic and inflate.  Spray papercrete on the back of the Mylar and when it's dry cut off the second layer of plastic and you should have a smooth Mylar covered reflector.  I haven't tried it yet but I think it will work.  I hauled rocks sand and top soil into the planter beds n the greenhouse today.  It must have climbed into the mid 50's F
