Artisan Archive

Hello,
I just got eng 4 and it says I can craft a bunch of different types of extractors. When I go to the installation tab of the general crafting tool, the only option I have is a wind power extractor. Where's the rest? I have even tried standing next to the crafting stations in town, but still no luck.

thx for the help
