@Siro:
the high end solution for that (if you have the ressources to creade IDSUs, you have the ressources for that too): set up a fusion reactor and supply it constantly with deuterium and tritium aswell as energy. take the plasma and feed it into a liquid tesseract (optional: extra tanks like railcraft tanks or the quantum tank).
and there you go, wireless high end energy. the setup on the receiver side is just another tesseract plus the plasma generator and a few transformers to get the voltage down. a nice and quite space saving setup.
Yup, that's the plan. It's just taking forever to get all the chrome I need for it (is there really not a uu recipe for chrome??). Time to automate some more centrifuges or step up the bee production. The IDSUs actually took a long time to build and I was hoping to use them as a way to repurpose my lava age (which I set up as eternal storm) once lava ceased to scale well. But I'd read some things about how it negatively effects tick rate to calculate rod to sky on lightning rods, and I've been having some tick rate issues (and unfortunately the item loss in me networks in the tickthreading mod has scared me away until its fixed; hoping Naller does well on their exams). The steam is a good mid range solution though. I'd get along fine with having to build steam turbines, but it seems silly to not use a better (in my opinion) tool when it is available. Steel isn't really an issue once you build an enderman spawner and automate minium stones (or breed the bees for minium & ender pearls or steel or both).
Can the new fusion reactor fit inside a single chunk? If it can I'd seriously consider trying to rebuild everything within a single chunk base because I'd read that tick threading didn't eat stuff in an me network if the network didn't sit on a chunk edge or cross boundaries.
