Parabolic trough facts for kids
A parabolic trough is a special device that collects energy from the sun. It uses curved mirrors to focus sunlight onto a pipe. This pipe contains a liquid, often water or oil, which gets very hot.
This technology is similar to a solar panel tower. It helps us create clean electricity from the sun's power.

How Parabolic Troughs Work
Parabolic troughs are designed to capture a lot of sunlight. They have long, curved mirrors that look like a "U" shape. These mirrors are very shiny.
Collecting Sunlight
The mirrors are pointed towards the sun. They reflect the sunlight onto a pipe that runs along the center of the trough. This pipe is filled with a special fluid. The concentrated sunlight heats this fluid to very high temperatures.
Generating Steam and Electricity
The hot fluid then flows to a central power block. Here, it heats water until it turns into steam. This steam is under high pressure. It pushes against the blades of a large machine called a turbine.
The spinning turbine is connected to a generator. The generator then produces electricity. This electricity is sent out to homes and businesses.
Why Parabolic Troughs Are Important
Parabolic troughs are a type of solar thermal energy system. They help us make electricity without burning fossil fuels. This means they produce less pollution.
They are a way to use the sun's energy for our needs. This helps protect our planet.
