A particle receiver is like a special container that can catch tiny particles, called particles of sunshine, that come from the Sun. These particles are called photons and they are like super tiny bits of energy.
The particle receiver is a part of a system called a solar power plant. This plant uses the photons from the Sun to make electricity. But before the photons can be turned into electricity, they need to be caught by the particle receiver.
The particle receiver is made up of lots of mirrors. These mirrors are like big shiny sheets that reflect the Sun's light. They are arranged in a special way so that they can all work together to catch as many photons as possible.
When the photons hit the mirrors, they bounce off and go inside the particle receiver. The receiver is like a big box that can hold the photons and keep them inside.
Once the photons are inside the particle receiver, they can be used to make heat. The heat is then used to make steam, just like when we boil water in a kettle. The steam is very hot and can spin a special machine called a turbine.
When the steam spins the turbine, it creates movement. And this movement is what makes the electricity. The electricity is then sent to homes and buildings, so we can use it to power our lights, computers, and other important things.
So, in simple terms, a particle receiver is like a special container that catches tiny particles of sunshine, called photons. These photons are used to make heat, which is then turned into electricity that we can use to power things.
