Copper–chlorine cycle

The copper-chlorine cycle is like a big water slide where we use copper and chlorine to turn hot sunlight into electricity that we can use in our homes.

First, we start with the sunlight that heats up water and turns it into steam. We catch the steam and send it through a pipe that leads to a big tank with lots of copper particles inside. When the steam flows over the copper particles, it causes a chemical reaction that makes the copper particles hot and releases much-needed heat energy.

Then, we send the steam into another tank that has chlorine in it. When the steam meets the chlorine, it creates another chemical reaction that makes hydrochloric acid and oxygen, which we can use in other ways.

After that, we send the steam back into the first tank with the copper particles. This time, the steam mixes with the hydrochloric acid that we made in the previous step. When the steam and hydrochloric acid meet the copper, it causes yet another chemical reaction that creates more heat energy and releases a chlorine gas.

We collect the released chlorine gas and send it back to the second tank, where it was mixed with the steam in the first place. We keep doing all these steps over and over again to create more heat energy and useful gases until we've made enough electricity to light up your home!
