With all the natural disasters that seem to be coming our ways, this article may become the outbacks, campers dream.

Studies by a professor at BYU found the sun could cook and then improved the design. Imagine, a disaster area, no wood, gas or matches, this device uses the sun to cook your food.

Might be something to keep in mind or to even try, "just in case".

There is also a discussion of a working COOLING model.

Anyone interested should read this.

Fairly innovative design, but an hour and a half for a boiled egg, could
probably be improved upon. Perhaps by increasing the over all size of the
collector.

Well understanding that this was developed for areas where they have to burn wood to cook and the wood supplies are almost gone, this is a great find, its cheap and anyone can use it.

In our world, any prep for bad weather, shortages etc, is a plus, not a minus.

The cooker is cool.

EDIT>>>>
What I found of interest, Other than making this is rather cheaply done and the heat source is FREE....

If you look down the page a ways, there is a pic of an updated design.

The first version had a plastic bag around the jar and it had to sit on a block inside the zone of the reflector.

The update that one of his students came up with, has a large glass Pot that takes the place of the glass, the metal bowl fits snuggly inside the glass pot, the outside of the bowl is painted black. A top that fits the pot is painted black on the outside and fits the bowl snuggly.
The glass pot is then placed inside the zone of the reflector, just about as easy as cooking on the stove or in the oven... and clean up would be just as easy as any regular dinner.

This would certainly be of value in an area where a hurrican has come through or a flood where cooking normally is not possible..

Disaster planning??? I suppose I am looking in that direction...

If you get the work out of the way

I was intrigued by the ability to use the reflector to cool stuff off at night to 20 degrees below the night air temperature.� Obviously I did not listen well enough in high school physics or I could have figured this out my self.� My teacher said."heat does not rise, it is pushed up and displaced by dense cooler air..."� I am sure he said something like take away the heat and stuff will get cool. The solar reflector reflects away infrared heat so stuff can freeze when the outside temperature is above freezing.� Will my coach will get colder in winter if parked on white cement rather than on black asphalt?� I think it would be fun to have such a solar oven to do vegetables for dinner.

We've played with all sorts of solar ovens but in and out of Boy Scouts.
There is an easy cardboard one that we made to bake a cake. I'd love to
get a large (>6') old satellite dish and make a real solar furnace out
of it. With a blackened pot/Dutch oven, you can make soup/stew in a
short amount of time. Heating various materials like mineral oil or
water could generate power too. I think that would also work to make a
Crosley Icyball and get the best of the hot and the cold.

Some place on my computer I have a schematic for a solar
refrigerator/freezer that does just about that, with the same principle that
the Crosley Icyball uses. It uses a solar reflector to heat the hot side
which is a length of black iron pipe, after the sun goes down, and the pipe
cools off, the chemicals in it draw the ammonia back to it, thus providing
the evaporation that cools the cold side.

That's the idea. You really need someone who knows how to work with
pressure vessels before dinking around with an Icyball.

Oh, I also taught the Scouts how to take a soda/pop can and polish the
bottom with whatever was on hand. Chocolate or toothpaste works good.
Once it was polished up, it can reflect the sun enough to start a fire.
Same principle as the solar furnace.
