Solar Cooker 2.0





Introduction: Solar Cooker 2.0

Cheap solar cooker



- A Small Box

- Aluminum Foil

- Small Cardboard Tabs

- Infrared Thermometer (optional. a normal thermometer can work too)

Step 2: Step 1:

Beggin by wrapping ALL of your box in aluminum foil like shown.

Step 3: Step 2:

- Cut one of the sides as so, and add cardboard wrapped in foil along the sides to hold it slightly up. (thickness optional)

Step 4: Step 3:

-With the lid of the box, make a V shaped piece that fits inside the box.

- You may glue or tape it down if you'd like, however, we left ours un-attached for purposes of being able to adjust it.

Step 5: Step 4:

You should end up with something similar as our picture.

Size of width and length is optional.

Step 6: Step 5:

Be sure to choose a very sunny day and place your project where the sun light will directly hit it from all angles.

In a small container, we put some water(this is optional, you can always test out anything you'd like) and took the temperature of it as soon as we placed it out in the sun.

We left it there for about 25 minutes and then went back to take the temperature once again.

After 25 minutes of sitting out, our water went from 73 degrees to 108 degrees.

In conclusion our solar cooker is pretty efficient as long as you give it more time.

    You can not cook or purify water with 108 degrees. The street on a hot day can read 120 degrees. Add some reflectors and check the angle of the sun touching the cooking pot. To check the angles you can use a square piece of paper and line one edge up with the angle the sun comes in and the 90 degree angle it bounces off the reflector to find the right angle for your reflectors.

    That's an awesome cost effective build :)
