DIY solar oven ?

[russ]

You are quite correct that I have no desire to construct or use a solar oven.

Try using one in the Alaskan interior in the winter. They don't work well when you get in the higher latitudes in winter months.

I do have an SOS Sport that is used when we are at the ranch. Being off grid and hot in the summer it makes sense. I can't see firing up the propane stove to cook unless absolutely needed and with the fire danger this summer outdoor grills are pretty much banned unless setup on a concrete patio.

Russ I have filled up 2 passports in the last ten years and quite a few in the previous 30 yrs...I think it is safe to say I have seen just about every squaller and slum area in most countries.. And if there are some I have missed its not important I have seen enough.
Its not expensive to make bricks that are adequate to keep an oven hot for hours.
its useless trying to explain this to you as you obviously have never used a good solar oven . but it may inspire others to give it a try as they have nothing to lose as it costs very little to build one. and they may actually have fun building and using one.

So you have traveled - next time look around while doing so - maybe that would help. I spent 30 years working outside the US and then retired to my my present location.

Try using one in the Alaskan interior in the winterAnd that would be about 1/2 a % of the worlds land mass.

The same would go for the rest of the world toward the North pole - same for the South. Not a lot of population but a lot of land.

What do you think is the best choice : DIY solar oven or buy one to professionnals ?That was the original question. There was more than a fair chance the person lives in a place where it does not snow all year or at Mt Everest heights or live where there is no land at the north pole.He most likely lives where there is enough sunshine to make its use viable.If he lived in the middle of Alaska or Greenland he would have been aware that there was inadequate sunshine ,and would not be asking if better to buy or DIY.
All you gave was negativity,nothing useful,nothing that would really help him make a decission .
I tried to give him my experiences of making one to show you dont really need to buy one and they can be made simply and cheaply with limited carpentry skills.I gave in the hope he would find that information useful and then may decide to "give it a go" Who knows he may have actually enjoyed making something useful and liked to use it.

The OP is an avid user of solar ovens. Who knows, a 1% type may come along and want to try it.
