This factory right over here, it looks like they're creating fabric from some kind of thread, or they might be sewing of some kind. And a human equipped with a power loom or with a sewing machine could produce much, much more than they could have ever produced before by hand. So the steam engine and things like electricity also create a revolution in transportation, the transportation of goods and people, but also the movement of information. This right over here is a picture of a steamship which you could use for trade, but you could also use it to project military power. This here is a railroad. Similarly, transport goods and people, but it also allows you to keep control over a larger swath of territory. And this is a telegraph.
