Right ok thats a good way of doing it without EE BUT the only problem is if you add all the EMC value of those materials what do you get? 8,192 and how much is a diamond worth? 8,192 I the entire process not only do you waste energy and steam engines for the quarys (or whatever else you used) but you come out with the exact same thing you could have dont if you dumped that coal obsidian (or brick) and flint in a condenser.
