Materials required: cardboard, aluminum foil, wood shavings or strips, scissors, handsaw, white glue, glass tube or clear plastic tube
Steps:
1, First make a support with wood chips, as shown below.
2. Then fold the cardboard and stick it to the backing with white glue as shown in the picture below.
3. Use white glue to glue the foil to the cardboard as shown below.
4. Adjust the angle of the cardboard and foil to form a concave arc, as shown below.
5. Cut two pieces of wood the same length as the glass tube to make a support. Stick it in the middle of the backing as shown below.
6. Install a post that can adjust the angle of the concave arc behind the bracket and the cardboard. Fill the glass tube with water, place it on the bracket and adjust the angle of the concave arc ofso that the glass tube is right at the focus of the reflector reflecting the sunlight, as shown in the image below.
Use a drink can and spray it with black paint. Put it in the sun, it is the simplest and most primitive solar water heater.
Method 1: Use a drink can and spray it with black paint. Placed under the sun, it is the simplest and most primitive solar water heater.
Method 2: 1. Fill a plastic bottle (preferably a beverage bottle) with an appropriate amount of water.
2. Prepare some mirrors.
3. Place mirrors around the plastic bottles and place them in the sun to heat the water using the reflection principle.
The solar water heater is a heater that converts solar energy into thermal energy, thereby transforming water at low temperatures. Heated to high temperatures to meet thepeople's use of hot water in life and production.
