[QUOTE="William Moore, post: 990849, member: 409515"] High efficiency lets you build smaller, otherwise portability is out the window. So yes, I am trying to be efficient. Parabola cookers can cook food, or melt cookware. It is important to place cookware above or below the melting effect of the tight focus. Stray reflections are an issue to the cook's eye, one of the big reasons to control where the light goes after first bounce. Ideal size depends on how many eaters there are. The Gibertini SE series in 75/85/100 are about right, and have a fold down LNB arm as well. If you want to try this, bolt the LNB arm do an upright 25mm x 50mm steel tubing that is anchored or weighted to the ground so it provides stability enough that the stew pot doesn't throw things off centre and fall out. I use a wire cage utensil holder big enough to hold a 125mm stainless steel canister painted black for a cook pot... The reflector will be on its back looking somewhat upward, and the pivot point allows for angular positioning of the dish relative to the post. Your cook pot will hang from the post where ever it needs to be to place the lower part of the pot in the focal point. I have a nice design for a less powerful cooker made from a 22 inch high bay ceiling light, with snap on glass cover. [/QUOTE]
