Solar oven project update

Posted by admin on Sep 29th, 2008

I started cutting out the frame of the new solar oven from scrap plywood laying around in the garage this past weekend. I have all of the sides cut out and ready for assembly, I just need to find my wood dowel pins to put the pieces together and I need to find a scrap piece of wood big enough for the bottom. I had to make the sides in two pieces because I didn’t have anything left that was big enough to make it solid. Here’s what I have so far:

The top of the sides are set at a 30 degree angle – I had read that is the optimal angle for solar panels somewhere. Once I locate my dowel pins and find a piece for the bottom then it should go together fairly quickly.

Here’s a picture of the one I built last summer. It’s got an old window I found in our garage from some previous owner, and it works pretty well. It’s lined with foil and the bricks in the bottom are to help keep the temperature a little more even. The test I did with it yesterday got it up to over 170 degrees. If it was built a little better and all the gaps and holes sealed up then I might be able to get it hot enough to boil water. I’ll be adding reflector flaps to the new one to ensure it will get more than hot enough for that. It currently sits on an old skateboard for portability, because with the bricks it’s quite heavy:
