Superconductor coil should be more expensive. By the time I had enough materials to fashion the fusion reactor, I had way more than enough coal, redstone, and 1/4 stack of gold blocks which was more than enough to make a coil. Maybe 4 redstone/2 gold bars per piece? So you have to actually spend some effort making it. (Nobody really uses gold for much, but it's nice to have something to spend it on).
Speaking of the fusion reactor, is it required to have all 3 heating elements? Can I mix & match them? What is the differences between them? I've only played around with it a little bit.
The autominer is the single coolest thing I have ever seen. Any chances of changing the recipe to use a personal chest and doubling the inventory space? That way your resources could be protected while they are flying around in SMP.
I think the we/dry vac is deprecated now... You can right click with empty cells to fill them. However, the hand pump could still be handy (haw haw) if you get the empty cells back (I haven't made one yet).
Ok, not sure if this even makes sense yet, but I just thought of it. I'd like to see Lithium used in some sort of complex battery system. Create a Li-6 Cell, compress/extract it into a lithium bar, then use the bar to make lithium sheets. When thrown into water, lithium sheets explode after a moment. The lithium sheets could be used to make a rechargeable battery that has nearly the same capacity as an energy crystal, with the added bonus of being able to charge things from the hotbar (like the RE batteries. I love that new feature). Perhaps some sort of cell deterioration could be implemented, so that you have to make new lithium batteries after awhile. Come to think of it, I with RE batteries worked this way as well. Or at least take some damage if they are fully discharged (lithium batteries hate that). MOAR batteries!
@ plutonium bomb: nuclear missiles already works like that, but the standard nuke tnt does not.
@ Heating elements: You can mix and match them. The ohmic heater is the most efficient, but it can only get the reactor up to a certain heat, where you will have to use another heater.
@ Lithium: The thing about lithium exploding in water is awesome. My science teacher made that experiment once... And the lithium batteries are great, too. However, lithium should be made directly into sheets, instead of using lithium ingots. The ingots would just be another item id used, unless the ingots would have a specific usage, apart from making lithium sheets. Also, it should not be Li-6 cells that would be used. rather just lithium cells.
EDIT: sorry for double post
is a good 1 becus its my fatret mushean
