It's so crazy that we've found like six different ways to use rocks to boil water. You'd think there'd just be two or three

It's going to be boiling water again... Isn't it?

Must be the water

I'm gonna need help identifying all of them. So far I have burn them, smush glowing ones together, and reflect radiation with them.

Coal. Set it on fire, use fire to boil water
Geothermal. Go down where the rocks are hot, use hot rocks to boil water.
Nuclear. Magic rocks get hot all by themselves. Use them to boil water.
Photovoltaics. Shape rocks into solar panels, use solar panels to power stove to boil water.
Concentrated solar. Use mirrors to reflect sunlight onto salt (a rock). Boil water with hot salt.
Put water in a glass tube. Use mercury (which comes from a rock) to draw a vacuum. Water boils at room temp under a vacuum.
Lob a space rock at the planet. Space rock vaporizes everything in a 100 mile radius, including water.

I'm sure we can think of more

Dam. Stack rocks to block water, use leaking water to turn propeller.

Ohhh right that makes sense. I was only thinking of ways to use rocks to boil water to make electricity. So I missed geothermal and disregarded photovoltaics.
