Just an efficiency thing that I've picked up along the way.

Anyway, okay, we can see that the iron ore is going in.

Let's check the configuration of the smelter and see what's going on.

We can see iron ore coming in.

We've got iron ingots coming out.

I can take these ingots even and put them in my menu, in my inventories rather.

Cool.

There's also a recipes tab here.

So we can make iron ingots or we can make copper ingots.

So it's important that if you're going to make a smelter over by the copper deposit to automate copper production, you can put a miner on the copper as well, of course, and the stone.

If you put a miner on the copper and then connect that to a smelter, you want to configure the smelter to receive copper ore to create copper ingots, otherwise it won't make it.

Yeah, cool.

So now we have the smelter and now we've learned power.
