and remember that you will need really good insulation in the floor at that point. if you have air flow under it, it will pull the heat out.

I considered the raised up situation and was trying to avoid raising it too high.  You may be right on that.  Likely I would never need to move it any way.  Probably just build it on skids like I originally planned.  Definitely will insulate the floor either way.  I found some walk in cooler panels that I may use somewhere....floor, doors, wall.

First post!

I am starting my investigation into the world of solar kilns.  The design in this thread looks very simple and efficient.

I have found some repurposed 4'x8' prismatic skylights



They are double pane and because of the design, they should capture more light in the morning and late evening.

Would they be a good choice instead of greenhouse plastic panels or double pane glass? They are $100 each and I was thinking of using 4 of them for a kiln 18 or 20 feet long.

Thanks,
Clint

Has anyone used the ZIP System OSB sheathing inside their kiln?  Prevents moisture and air infiltration.

The skylights shown will indeed collect energy, but the part that is not getting solar input at a reasonable angle will be a source of heat loss, which will make the benefit much smaller or even negative.  

The key collecting area is the area perpendicular to the sun.

So...at 3am Saturday morning, a strong weather front moved through our area. We had major straight line winds at my home...caused my rear door to blow open and scatter pictures, breaking some glass. I thought a tree had fallen on us! Thank God it was just the door blowing open with no real damage. I walked around the next morning and discovered that my kiln had been blown off the piers it has been on since construction. Iíve needed to move it to another location for a while, and the Lord says itís time. Next week....

Guess what?!! Nine years after building the kiln, the day finally came to test the trailer capabilities. It worked like a champ. There was no rot on the main support timber....yes! We jacked it up, and slipped on the tires, which actually held air after all these years. I backed up my Ď95 Chevy van  to it, and SLOWLY backed it to its new location. It will be fairly sunny in the new area, but not as good as where it was. By moving it though,

 

 itís no longer sitting in the front yard...wife is happy! That makes me happy. We leveled it off and set it on concrete blocks. We then removed the axle and hitch, which was installed to be removed. It is now in itís own little kingdom, out of our way. Here is the new location:
