I was getting together a list of Mountain House stuff together for my upcoming vacation and came across this style of solar oven, looks like a folder, might give some ideas.

That one has caught my eye, too. Seems expensive, but if it works, hey.

I made a trip to the city yesterday and picked up a cheap closed-cell foam pad and a space blanket. I forgot to get spray adhesive, but the hardware store here in my town should have that. The pad is 20" x 72". That makes it about the same size as my existing cooker, once I make a few necessary cuts.

The plan is to follow the instructions for making the fun-panel, using velcro to secure the seem. That way it can be used as either a ground pad or a cooker. Pics to follow.

A quick refresher of the fun-panel

Here are directions for making the fun-panel:
http://solarcooking.wikia.com/wiki/Fun-Panel

And here are the materials I have assembled:
IMG_4765.JPG
I am working out a strategy for laminating the emergency blanket onto the camping pad. I think the best method will probably be to tape the emergency blanket out flat, then roll the camping pad out onto it, spraying the adhesive as I go.

I opted for the Sol brand of emergency blanket because it will stretch a good bit before tearing (unlike mylar), and so should take more abuse without becoming tattered. I had planned to use mylar wrapping paper, because it comes on a roll with no creases and would be easier to apply (I think), but I couldn't find what I had in mind and did not want to spend more time in the city than I had to.

Once I have successfully laminated the shiny stuff to the camping pad, I'll cut off a piece 18" long and install velcro on both long edges. Then I'll mark all the fold lines on the back (non-shiny) side. Then I will score these lines, maybe 1/2 way through the foam. I am hoping that the folds will be stiff enough to take out most of the curvature in the foam (from being rolled up), but if not, I will add some foil tape to the fold lines to stiffen them up a little.

Here's the basic layout:

The velcro will join the small piece alongside the big one, as well as close the seem when deplyed as a solar cooker. I'll add some velcro on the end of the big piece, so that the small piece can be returned to it's original position (before cutting) and make the camping pad full-length again.


I'll try to get photos of the whole process. I hope to end up with a camping pad that can be easily re-deployed as a solar cooker. I am sure that I will find other uses for it as well (snow melter, umbrella, signal device, lantern reflector, rain-catcher, solar still, other stuff...)

Really look forward to your unfolding of the project.

Found this on ebay 30"x40"

I've been looking for a good place to do the glue up. Too cold outside, and I can't do it inside with a baby present (fumes). But my mom is traveling and I have to water the plants. Figured I might use her garage. The fumes should dissipate before she gets back, so all she'll know is that I swept the garage (such a good boy :-D :-D :-D ). The baby can nap inside with a monitor nearby. Maybe later today.

I had to scrub this mission- flight cancelled. @ weeks until reschedule, but it's warming up, so maybe I can sweep off the concrete pad and do it outside. I'll post...

Ask you Mom to go to the store for you tomorrow or some other excuse to have out and about for whatever time you think you need :D

The weather is unpredictable. I started disassembling my greenhouse last Sat. and last night we got 5" of snow :roll:

Bummer! Hopefully it doesn't cave in from the weakened structure....

It all melted off by noon today....hooray!!!

Big flocks of robins in my yard today chirping without end, ahhh, so nice to be able to hear them again ;) They are in my White Ash trees eating the blueberry size seed berries. The field is still covered with snow so they took to the trees for meals. In the spirit of will edibles I should go out there and gather some berries for me :D

Last Sat. morning I saw a coopers hawk come down and snatch up a robin for lunch :o Bird eating birds. Driving down the freeway one year a peregrine falcon came along side my car flying parallel in hot pursuit of a mallard duck. Came to an overpass and both veered up and to the left out of sight, never saw them again.
