If you are fed-up of ordinary inefficient solar cooker designs and wondering how to make a solar cooker that works in a truly effective way, then probably you have reached the right destination.
A low cost solar cooker design that heats up instantly and actually cooks your food in minutes has been meticulously discussed here.
When it comes to making of solar cookers, harnessing solar energy most efficiently becomes one big criteria. The idea presented here is perhaps one of the fastest heating solar cooker designs.
Making a Super Efficient Solar Cooker
You must have read and studied many different solar cooker designs, but do they really work effectively? Precisely speaking most of them work only under cent percent ideal conditions. Moreover, cooking over many of these cookers look pretty impractical and cumbersome.
The main criteria for achieving optimum results with solar heat lies in efficient collection and concentration of sun rays. Solar rays falling straight over a surface may produce just ordinary heating; however collecting them inside an air proof enclosure covered with glass may help enhancing the accumulated heat to more than 50%.
This happens because the usual sun rays which are normally made up of long waves make their way successfully through the glass cover into the box but the reflected rays from the container surface are converted to short waves which by the virtue of their property get trapped inside the box and are unable to escape from the glass cover resulting in the increase in temperature of the enclosed area.
However, acquiring temperatures up to levels that would actually be suitable for cooking purposes looks a big ask as far as getting it from the natural resources is concerned.
Solar cookers made from multilayered boxes with glass covers definitely generate high temperatures inside them, but can never reach temperatures that would cook vegetables or meat optimally.
These cookers are good only for heating water or food that’s already cooked, furthermore as already discussed placing and withdrawing food containers over them doesn’t appear clean enough and may cause a lot of discomfort
The present content will not only answer the question “how to make a solar cooker,” but also a perfect solution to effective cooking using solar power.
Let’s peek into the proposed design and see how it works.
The design produced here is not new and has been exploited over and over again. As discussed in the previous section the main criteria of effective and maximum concentration of the solar rays over a tight spot is the basis of this design.
How to make a simple solar cooker at home:
An appropriately sized bowl painted black over its bottom round is fixed through welding at the top end of the pipe as shown in the diagram.
As the sun rises, the rays incident over the cone’s inner polished surface gets reflected at a certain angle and get concentrated around the top end of the pole where the welded bowl is positioned.

solar cooker is not practical in home….people dnt cook food in terrace what abt
1. pollution dust
2. crows and incests
3. difficulty in cleaning

Dear Swagath, I’m sure you must have known about the Battery Desulfator, can you give a good schematic for the same
Swagatam says
You may check the following article, though it's not tested, it should do the job:

sir,my aim is not to make different types of solar cookers,but to convert this idea into an experimental project by relating the efficiency….any way let me try this idea itself sir….thank u
Swagatam says
Hi Surya,
I haven't checked this unit practically so it will be difficult for me to analyze everything in detail.
You may refer the following link for exact info:

In fact if you google – how to make a solar cooker, you will find a huge DIY data about it.

sir,again i have changed my topic;i am interested in doing an experimental project regarding this;sir,can we relate the amount of water boiled and the time of heating and the surface area of the tin foil?I mean to find out the efficiency of the cooker and relevance of this in a large scale?please suggest me suitable ideas regarding this for doing an experimental project

sir,sorry 4 disturbing you….can you pls suggest me some solar applications like this,which are cheap….?i have referred almost all circuits regarding this solar energy…but the solar module/panel is very costly and also is not available here….pls help me sir
Swagatam says
Hi Surya,
The above project is the easiest and effective, other better projects will require a solar panel.
Or may be you can buy a small cheaper solar panel and make a solar cell phone charger circuit.
Regards.
surya s says
thank you sir…will try it
surya s says
sir,what should be the height of the metallic pipe?what aboutthe time taken?
Swagatam says
Th pole height can be anywhere between 2 to 3 feet depending upon the users convenience. I am not sure about the time, it will be most efficient between 10 am and 2 pm and will produce very high temperatures if aligned perfectly.
surya s says
thank you sir,i have selected my topic as APPLICATIONS OF SOLAR ENERGY IN DAILY LIFE..I will try all these….for the desalination plant,T SHAPED tube and funnel having tap also is not available sir..
Swagatam says
Very nice Surya go ahead… I wish you all the best.
You can make he above solar heater project, it can be used in rural areas for cooking food.
