So, you know how we use electricity to power our homes and devices? Well, most of the time, that electricity comes from burning things, like coal or gas, which is not good for the environment.
Scientists have been trying to find a way to make electricity without hurting the planet, and one way they are doing that is through something called a spherical tokamak.
A tokamak is a funny-looking machine that scientists use to try to create fusion energy. And fusion energy is what powers the sun!
Now, a spherical tokamak is a special kind of tokamak that looks like a squished ball. It's smaller than other tokamaks, but can still create a lot of power.
The way it works is that scientists put a special kind of gas, like hydrogen, into the machine and heat it up, just like in the sun. When the gas gets super hot, the atoms start to smash together and create energy!
This energy can then be turned into electricity, and because it doesn't come from burning anything, it's much better for the planet.
So, scientists are working really hard to make these spherical tokamaks work even better, so one day we can all have clean, green electricity without hurting the Earth!
