By the time I build it I am feeding it using ender chests from automated processing systems fed by an ender quarry and using a basic computer craft setup to regulate it. After that a 9x9x5 that makes over 8k/t passive, and will eventually fuel 4 turbines making almost 100k/t that will get me to endgame unless I go deep in Draconic. It will mine way more than enough to feed the reactor and start making parts for the bigger reactor and I rarely have to add fuel once I load a few stacks into it. I start with ender IO sterlings, and go straight to a 4x4x3 reactor that makes 1k/t to run a BC quarry. I've used most of the power gen systems available in Infinity and nothing can match big reactors for either cost per RF/tic or total output. So in summary: not easy but consider it a nice challengeĪs a bonus in the end you will have a world that has guaranteed no instability. That dimension will use just 10RF/tick and has tons of lava to pump out.
And Shallow Ocean will incur a cheaper cost on the liquid lava dimlet. It will give a relatively shallow ocean but it is flat and thus easier to pump out then (for example) lakes or liquid orbs. This can be only used in combination with any of the 'island' terrain types. A good feature dimlet that gives you a relatively easy way to pump out liquids is the 'shallow oceans' feature.So that's a choice you have to make first.
On the other hand it is much easier to pump or quarry the liquid/material if it is an ocean or flat terrain as compared to having to get it out of liquid orbs or tendrils scattered through the sky. That's because you will usually get more of it if you use it for a terrain. First a Liquid or Material dimlet used in combination with a terrain dimlet will be more expensive compared to having the same dimlet with a feature dimlet.The goal here is to use little RF/tick for the dimension but still have plenty of lava.
