A parabolic is an improved box cooker.
it's pretty safe to cook in a solar oven, but it can catch on fire just like any other oven
There are a number of retailers which offer solar cookers. You can try visiting websites such as India Mart and Sun Oven to see some examples of what is on offer.
There are a wide variety of solar oven cookers out there, which is a great way to take advantage of the sun�۪s energy and to eat delicious meals (slow solar cooking retains most all the moisture and nutrients of foods ��� and tastes great!). Read more about it at www.modernsurvivalblog.com.
that depends on what you mean by "better." Solar ovens can operate without any electricity or gas, but then, you cannot use a solar oven at night or on cloudy days. Electric ovens can be set at specific temperatures, which is more difficult to do with solar ovens. Electric ovens cost quite a bit of money, while a solar oven can be made with not much more than a cardboard box and aluminum foil. So it all depends on your circumstances and what you are trying to do.
Short answer 150° C (300° F). My personal cooker only reaches 130 degrees, but a friend of mine has recorded his at over 150° C (300° F)! You only need about 90° C (200° F) to sufficiently cook food, and most box-style solar cookers (even if you've made mistakes in making your cooker) have no problem meet this temperature. Make sure to measure the temperature inside your cooker before trusting it to cook anything though. I suggest trying to boil water, which boils at 100° C (212° F), or using a thermometer. Some more advanced panel designs and parabolic cookers can get just as hot or hotter than a stove-top burner!
Double oven cookers are very useful when it comes to cooking a large meal when you need everything to be ready at the same time. A double oven cooker has a higher capacity than a single oven cooker and comes in very useful when cooking Christmas Dinner.
yeah probably:?
I believe it does, if I'm not mistaking you'd have to run the crock pot for 70 hours to equal the power the oven uses in 1-2 hours.
A solar oven is made up of aluminum panels and won't catch on fire itself. However, it is possible for the food being cooked within the solar oven to catch on fire much like a magnifying glass focusing light from the sun can catch a leaf on fire.

well a solar oven reflects light off of the sides of the foil and it creates heat
