Aroma, here's his code (IC2 Beta Planner):

Laziness or not, it creates a level of expectation that should either be removed or leveled properly.
I think if that were the case, it wouldn't need 15, but only like 4-6.
The miner used to have JUST enough slots to hold everything. With the advent of multiple stone types (Diorite, Granite, Andesite), 3 additional slots are taken and it is likely a miner will run out of space.
Why this is significant: Where before a miner might have taken up 2 slots with 64 cobble and 26 cobble, now it might take up 4 slots with 51 cobble, 1 Diorite, 20 Andesite, and 18 Granite. In a recent real-world test on level 49, 15 slots were filled with cobble x5, Diorite (1 block), Andesite (20 Blocks), Granite (18 blocks), dirt, tin, lead, copper, iron, uranium, redstone and coal. There is still the possibility of diamond and gold, and we are already at 16 blocks. I removed 3 cobble to make room for testing to bedrock, or else the redstone would have been on the ground.
I know a chest and an ejector would also work, but if that was the point, why not have no space at all? I feel the space is there to allow a miner to hold all items at a significant level above bedrock.
HV cable tooltip says "2048EU/t, .80 loss/t" no matter how insulated it is. Is this intentional, or should I submit a bug report?
If intentional, what is the point of 3x ins HV cable?
Speiger, have you ever said "your code is bad, use this exact code I fixed it" with the exact code / fix attached or shown? Just wondering.
How do the new water devices work?
I know how the old ones worked. I think I made a water turbine, and it said something like "only works in ocean biomes". I'd rather have an explanation than screw up again.
OK, necropost... but in 1.10 you could use tanks with either Fluid pullers or Fluid Ejectors. Not SUPER cheap, but not too bad. If you need it shut off, pull the ejector / puller from the start.
The discussion and results are all much appreciated. Thank you.
I bow to your superior reactor engineering!
Ok, two more challenges and one more question.
Question: Do you think there is any more to be gained beyond 704?
Challenges:
1. Create a reactor that generates base 690-700 heat, so it will not need an additional fluid exchange but is still significantly better than 672.
2. Create a reactor that requires only one type of fuel (Only Quad Rod, or Only Double rod) so it can be better automated
Omicron, I found the reflector reactor to be the hottest stable reactor for fluid reactor heat generation. I have not seen a reactor generate more than 672 heat per tick, and I would love to have a more powerful one. The subsets of the main one are because I don't like rebuilding reactors, this allows plug-and-play of only key components.
On the flip side, I've found the 420 reactor to be the highest-output reactor EU-wise.
I submitted these because it looked like Korlus was asking about high-efficiency reactors, and I use these for their efficiency. Using reflectors makes them even more efficient, so I do.
If you have a higher heat reactor that only uses IC2, I want to know!
Here's the reactors I use, in the new format.
6-chamber, 320 EU, 640 heat, 16 uranium. Builds easily into the next one.
EFF: 4.0

6-chamber, 240EU, 672 heat, 8 uranium + 16 iridium, for efficiency or for heat reactors:
EFF: 6.00

6-chamber, 420EU, 672 heat, 28 Uranium, for when you just need more EU and don't care about efficiancy:
EFF: 3.0

6-chamber, 260EU, 603 heat, 12 Uranium. If you want slightly more efficient than 4.0.

Edited to add efficiency.
Any chance we can have a Qty added to the replicator? I've often needed 10 or 20 of something, but I didn't need the 22 I got for leaving it on continuous.
Just a number with + and - buttons above the "single run" button would be good enough for me, I've never needed more than 20 in one run, and that would be good enough for me.
Alternately, add redstone input, and people can turn it off once X items pass through a funnel or pipe.
I second the question about lithium... but only for curiosity, mind you 
Speiger, you were doing so well at a calm, thoughtful discussion... until that last sentence. Inside voice, not outside voice.
I appreciate the responses and input. Maybe I'll just overclock things then.
I still think a method for making wire faster would be a good thing. There are dedicated extruders in real life; why not in Minecraft?
Alternately, how many overclockers does it take to make a machine work 9x faster, and how many transformer upgrades would it take to power the machine at that level? Alternately, do you have a bank of metal formers in your workshop in minecraft, and if so, do you find that level of repetition enjoyable?
My goal it to keep the upgrading and building enjoyable. I did not find making 1500 wires enjoyable because of the time it took. I am suggesting some way to make that time get reduced.
Oh, and I've destroyed 3-4 hammers just to speed things up. Making 128 copper plates for heat conductors is not any more fun.
I can use the hammer to make 80 plates at once for 6 iron; there is no way to make 3 wires per bar except with the machine. If I use clippers it's only 2 wires, using 50% more material (not acceptable when you first make your nuclear reactor)
Math:
43 motors from my reactor setup for component heat vents, overclocked heat vents and advanced heat vents.
let's say 3 dense ejector build-outs, 1 puller build-out = 4 motors
47 motors * 16 wires each = 751 wires, / 3 per bar = 251 bars of copper for one reactor into wire.
251 bars at 3 seconds per bar = 12.5 minutes waiting for wire. If you pre-cut the wire, would need 12 spaces to hold them all; basically a chest just for wire (and plates, let's not be silly about storage). If I forget, it will take minutes to get the wire I need.
If the clippers made wire at 3:1, it would be acceptable. Frankly, I haven't tested them in some time; it may have changed.
I made a MOX reactor that works pretty well... but outputs only a similar heat to the same reactor with quad cells. This does not make it more efficient to me.
