To progress to the industrial age you will need 20,000 money:
20 Titanium Ingots
20 Batteries
20 Bioethanol

Titanium Ingots are crafted on the Stone Furnace at a 1:1 ratio using Titanium Ore.

Batteries are made on the Generator. To run the generator, it requires either you run, or an animal run on the "hamster wheel" If you run you will lose stamina, if an animal runs, it will run until it perishes.
I recommend setting up a square pen with 1-3 generators and 1-2 breeding stations inside, both of these are made on the work bench. Additionally, craft multiple "Monster Prisms" which you will throw at wounded or low level monsters like pokeballs to capture animals. I used cows because I like when they moo. As they begin breeding you may need to catch your tamed baby cows and then throw them on top of the breeding station. Eventually your pen will fill and they will sort of auto walk into the generator and breeding stations.

While the battery process is semi automated, you will what to set up a good amount of wheat boxes, I recommend 10-20. You will also want to have a well, be close to a water source, or chose the skill to create water magically. You will do this until you you can get a sprinkler or two which can water up to ~8 wheat boxes with careful placement. Harvest the wheat and take it to the "Cooking pot" and make "Wheat Flour" This is made at a 2:1 ratio.

Once "Wheat Flour" is made, move it to an "Aging Station" which will convert the wheat to "Bioethanol" at a ratio of 10:1 Therefore you will need 200 wheat total for this step.

This can be obtained by being invited in a world in which this age has been unlocked.
