I got another question. Answered

Guys..i got another question.
I'm interested in this one project. Here's the link (http://www.tuvie.com/portable-parabolic-cooker-collects-solar-energy-to-cook-your-food/comment-page-1/#comment-19374)
It heat up oil using the solar and the oil is the one which produce heat to the coil which will be use for cooking.
My question is do you guys have any idea what oil is being used?
I'm trying to find out about the oil because that solar cooker is much more easier than what I'm planning to built. That's the only problem about the solar cooker, I don't know what type of oil is used.

I imagine any decent engine-oil will do the trick, since it is staying in the closed system and not coming in contact with the food.

Who said petrol ? Engine lube will handle 150 deg C for a long time. Silicone oils ~200C

. It depends on how hot you can get the oil. Since you will have purged all the air from the system, thermal decomposition should be your main worry.
