ELI5: Explain Like I'm 5


A heliostat is something that tracks the Sun's movement and reflects the sunlight. It looks like a mirror that can be rotated and pointed in different directions. The heliostat works by reflecting sunlight onto a particular target, like a building or something else. This is so that the target always gets the same amount of sunlight, even when the Sun is moving across the sky. Heliostats can be used to help make energy from the sunlight, or to light up buildings or streets at night!
