Solar is a device which Run from sunlight
Because if we will not paint then the heat is reflect on the solar cooker
to save energy and to make it portable
The key to solar ovens is basically a four-step equation for you to solve. You need reflectivity, directivity, a heat sink and "containment" to stop moving air. Reflectors are needed to redirect the sun's rays. The mirrors must be pointed in what is generally the "correct" direction, too. Third, you need a big black heat absorbing pot or vessel to put your goodies in. Lastly, it's a good idea (great, actually) to minimize air movement around the cooking unit. Moving air will act as a convection mechanism to remove heat from your pot. You don't run your oven with the door open when you're cooking, do you? No, you don't, and you know why. The same thing applies to the solar cooker. There are a number of "designs" for home brew solar cookers, and some of them are pretty darn good. Those who posted the "how to" in various places on the web have almost always actually constructed and experimented with them, so they "designs" are proven. That's a plus for you. Rather than write out or cut and paste directions (which is a WikiAnswers no-no), we'll just provide you with some links to different ones. You'll find those links below. Clean Pizza Box # Aluminum Foil # Plastic Wrap # Duct Tape # Scissors # Pen or Pencil # Ruler Step 1: Completely cover the pizza box with the aluminum foil Step 2: Cut a 1in. hole in the top, center of the pizza box Step 3: cover the hole with plastic wrap Step 4: Place the solar cooker into a nice, sunny area and start cookin' NOTE: Place whatever it is you are cooking inside the pizza box, where you are able to see it through the hole
solar energy from solar panels :) ;)
Venus is the 2nd Planet in Our Solar System. Our Solar System is in The Solar Neighborhood. The Solar Neighborhood is in The Orion Arm. The Orion Arm is on The Milky Way Galaxy.

A parabola solar cooker works the best and fastest
A solar cooker and a pressure cooker are two completely different ways of cooking. A pressure cooker can still use a heat source like a gas or electric cook top. A solar cooker is as the mercy of the heat of the sun and the contents will only cook as well as the amount of heat it obtains.
A panel cooker is a way of using solar power to cook an item. The advantage of using a panel cooker is that it is using solar energy and not electricity.
horace de saussure invented the first solar cooker bout the year 1797

because he did not have stoves back then so he made a solar cooker to heat his food up

Depending on the type of solar oven/cooker, it can be chilly outside, but if there is direct sunlight and especially a high UV index, the cooker can get very hot.
You can use a solar box and compare.
yes solar cooker's can achieve 250 degrees farienhiet.
