Tesseracts are not that expensive, particularly when you're factoring in (if this whole thing worked, which it apparently doesn't) that the end result would be completely free endless energy. All you really need to make the tesseracts is:
- Some tin (trivial to obtain)
- 2 shiny ingots (if you have any TE3 infrastructure at all, this is also trivial)
- 1-2 stacks of ender pearls (trivial to obtain with mimichite)
Add in about 8 blaze rods for the ender tanks (also easy to get if you can find a nether fortress) and you're set. I don't see how this recipe would be all that difficult, unless you're bottlenecked on blaze rods or something.
Let me double check here...
Ah, yes, see it's 3 tin dust, 1 shiny dust, and a bucket of resonate ender for the enderium blend. Cool beans. Then it's blaze powder, coal dust, and sulfate (IIRC) a bit of redstone for a 2 blazing pyrotherium. Take 2 enderium blend and throw in a induction smelter(or w/e from TE3) for some Enderium Ingots. Then mix those with hardened glass(lead and obsidian dust in the same thing), and a diamond, and get a tes' frame. Take that and fill it with 1 bucket worth of ender and you have a filled tes' frame. Mix with 4 bronze and 4 silver for 1 completed tes', of which you need two to get anything done.
That's a stack of ender pearls or a complete pair of Tes'. Trivial with Mimichite? Hardly, since Mimichite doesn't work on Ender Pearls. Or most mob drops.
