I've been converting redstone to glowdust, then auto-workbenching that to glowblocks. Is that less efficient?
According to the wiki, yes. It's a lot easier in general to aggregate glowdust anyway, a bit less messing around with converting.
A bit of math shows you're right.
154 aggregator-minutes takes 154 redstone to 154 glowdust, convert to 32 glowblocks + 26 glowdust, convert to 1 diamond ore + 156 redstone, restart cycle.
129 aggregator-minutes takes 43 glowdust to 43 glowblocks, convert to 1 diamond ore + 11 glowblocks, convert to 1 diamond + 44 glowdust, restart cycle.
So at say 16 aggregators running at 100% power (glowstone blocks above, below, and on two sides), 8 minutes per diamond versus nearly 10 minutes per diamond.
EE's been fun, but when I upgrade to 1.9 plus IC² + BC + RedPower, and start a new world, I'm not going to put in EE. Maybe I'll play with SDK's guns or Better Than Wolves, assuming they all get updated to 1.9.
Edit: Oh, hey, trees to diamonds. 64 logs, furnace to 64 charcoal, transmute to 64*3 redstone, transmute to 64 coal. Transmute 12 dirt to 8 flint, make 8 coalballs, compress. Transmute 2 dirt to 1 clay, make clayballs, make bricks, make brick block, make coalblock, compress. Make a shovel out of the industrial diamond, transmute the shovel into a diamond.
