Solar Baked Stucco (Walls)
I have used a Solar Parabolic Cooker for several years now, and know that safety is a necessary precaution with any instrument designed for cooking with high heat and temperatures.
Despite knowing all of the safety measures and precautions for the safe use of a parabolic, I left my Solar Burner Parabolic on the back patio turned away from the sun, but up close to our stucco back wall, thinking that it would be safe and fine there for a while.
When I finally returned to the back patio after a few hours I found etched into our tan stucco two moon shaped, bright red spots where the stucco had been burnt out. And when you passed your hand over the burnt areas the stucco fell like fine dust to the ground.
The off-angle of the parabolic still allowed for a focal point to form and to create enough heat that it caused our stucco to burn.
I also made the same mistake about a year earlier with a small parabolic that I was transporting inside of our van.
I supposed that inside of the van and with the windows blocking most of the UV rays that I would not have to worry about covering the dish of the parabolic. Luckily I smelled the burning ceiling material before it could do too much damage.
I have the photographic evidence of my negligent actions to be able to show others "what not to do" with a parabolic cooker.
