After you have your Metallurgic Infuser and Enrichment Chamber, the next machine to craft would probably be the Crusher which does exactly what you think it does. This will help you in a number of things, including ore tripling. Up until now you have been probably using the Heat Generator, which isn’t that efficient. My favorite early and middle game generator is the wind generator. This gives you a large amount of power, and isn’t to hard to craft. If you want to get the maximum amount of power out of your wind generator, put it at a high altitude, This can give you almost 4 times the power that you can get at ground level.
