Unfortunately, unless you either a) farm a fair bit of experience, or b) get lucky, you're not guaranteed a Fortune enchant on any item you make, even if you're enchanting books. Shit, I experimented with it, myself, on a test map and it took me about half a stack of books (and 30 times that amount in xp levels) to get a Fortune book.
Though, if you end up in something like a redwood forest or similar biome with gigantic trees...cut them suckers down, and you'll have more wood than you could ever possibly need. Burn that into charcoal, grab experience, chop more wood, use charcoal to make more charcoal, repeat ad nauseam, and get a decent amount of experience per stack of wood you burn into charcoal. Hell, if you do like I did, and tack on Treecapitator mod, it becomes even easier, because you can actually cut the base of a tree and have the rest "fall down," instead of having floating bloody trees. I know some people will gripe, but its an efficiency and fun thing, for me. Spending 10 minutes hunting down a log hidden amongst a horde of leaves (so the thing will properly decay) on a particularly large tree is not fun, for me. I just want to cut the thing down, get my shit, and use it for whatever purpose I see fit.
GregTech, by default, is a bit annoying, with it altering several mechanics and recipes in ways that, to me, come off as more fake difficulty rather than actual challenge. Making a player be -required- to use a compressor (and, by extension, EU) just to make a simple storage block, then needing a macerator to turn that storage block back into ingots? That, right there, is bloody tedious, if ya ask me. Its not fun, its not challenging, its an extra step just for the sake of making everything require more damn steps to get to. Hell, the solar thing would bother me, but I personally don't use solars, like, at all, since I'm much more partial to lava. Lava just looks better, lol.
On the topic of free energy, players will always find a way to get what they want, even when working within the constraints of a given game and/or mod(-pack). If GregTech somehow, magically, fixed every known infinite energy bug in FTB tomorrow, I can pretty much guarantee you that, by that time next week, someone will have found a new way to get endless power again. Its not a question of if, but when. Trying to fight exploits in a game like Minecraft is an uphill battle in a blizzard, you will never succeed. You can close a lot of them down, and do so quite well, but there will always be bugs, there will always be exploits, and the players will find a way to get what they want, without resorting to cheating or modding.
That said, GregTech's config file could use some extra comments explaining some of the more...arcane bits of it. I pride myself on my ability to discern the meaning of obscure things one finds in places like config files, and even I get stumped by some of GregTech's config options, since I've got to go by name alone. I am trying to make something that'd make editing configuration files a bit less of a hassle...not having to fumble with whether or not you need to use Wordpad, or could get away with just Notepad, finding which section, in particular you're looking for, and perhaps, batch editing of options. Twill take some work, most of it trying to interpret what seems to be the Forge-standard config structure, but between actually playing the game, reading, and now college, my time available for such endeavors is less than what it used to be.
