Of course, we first need to find a way to focus the sunlight onto a small spot. To make a solar cooker with curved reflectors, you can first make a stand. Of course, it must first be strong and safe. Adjust the reflector to allow sunlight to focus on the center of the stove and attach the reflector. Sunlight moves, so you need to adjust your position from time to time to use as much solar energy as possible.
I've heard about the efficiency of solar cookers since I was a child , but why are they? not popular in rural areas now? You can produce solar energy with local methods. Frying pan?
Preparing materials: Collect several pieces of aluminum foil from cigarette boxes and a satellite antenna (a diameter of 1.5 meters is optimal).
Production process:
1. Glue the foil as flat as possible to the inside surface of the antenna.
2. Remove the tuner and associated cables from the antenna.
3. Place an enamel water cup on the fixture where the high frequency head is located (the bottom of the water cup can be painted black to improve heat absorption).
4. Adjust the elevation and direction of the antenna so that the antenna focuses solar energy onto the enamel water cup.
5. Wait, it will open in a moment.
Congratulations on using 300 yuan to make a solar cooker worth 100 yuan.
The situation you mentioned should be possible, but it can only be used at a certain time and the limitations are relatively large.
It is understood that some box-type solar cookers are in the situation you mentioned.
Currently, solar cookersThe products produced by factories are very mature, easy to operate, simple in structure and low in price. You can find a professional manufacturer to inspect them.
Many regions are now promoting solar cookers on a large scale.
