A solar cooker is a device that collects solar radiation to obtain heat for cooking. It burns no fuel, causes no pollution, is faster than a briquette stove in normal use and has the same speed as a gas stove.
Buying a solar cooker is not very cheap. In fact, we can make a solar cooker suitable for preparing snacks ourselves.
Materials and methods
1. Find a concave reflective bowl on a large flashlight.
2. Use rigid foam plastic or wood to cut out a cylinder about 4 cm long, with a diameter that can fit tightly into the round hole of the reflecting bowl.
3. Drill a thin hole transversely in one end of the cylinder, insert a wire with a diameter equal to the diameter of the hole, then bend both ends of the exposed wire 90°. , leaving 5 cm on each side.
4. Insertthe cylinder into the round hole of the reflecting bowl, then insert both ends of the wire into a plastic foam or wooden base plate.
5. Sharpen both ends of a thin bamboo stick, insert one end into the cylinder in the center of the reflecting bowl, and insert a small piece of potato into the other end.
Now place the device in the sun with the reflective bowl facing the direction of the sun. Then, patiently adjust the length of the bamboo stick so that the inserted potato is exactly in the focus of the light. Before long, the potatoes will be roasted in the sun and become fragrant.
Prospects of solar cookers
A solar cooker is a device that collects solar energy and uses it for cooking and boiling water. The key element of the solar cooker is the condenser mirror, which not only offers the choice of mirror material, but also the design ofthe geometric shape. The most common reflectors are silver or aluminized glass mirrors, but there are also polished aluminum mirrors and aluminized polyester film materials. With the progress of times, advanced technology has gradually entered people's lives. Solar energy is an energy-saving and environmentally friendly equipment in the 21st century. In today's increasingly scarce environment, solar energy environmental protection equipment is becoming more and more popular among people.
Protecting the earth is our common responsibility, and maintaining ecological balance is our common wish. Therefore, environmentally friendly solar products will occupy most of the market and almost every household will be able to use them. Stoves require energy like gas, electricity, etc. If you use solar cookers,you will save a lot of energy.
