I was assuming no buildcraft, but given his mention of transformers, I would say it's safe to say he has buildcraft
For my part, I didn't mean Buildcraft 
But as a pumping lava device, BC pump + BC pipes are better than IC pump (because not limited to a 9*9 area)
No, I mean put a miner down with a pump next to it in the Nether, put empty tin cells in the pump, and then put the lava cells in a geothermal generator for 20,000 eu each.
30 000 if the Geogen is directly on a side of your pump 
(And you don't need cells (chest + bucket or nothing) [I believe]
Just made Geogens less OP.
What ? You ... didn't understand what I said ... the problem is that GreenGen are already OP (if they are not, could you tell me please why solar pannels are so used ? you can answer "because there is many people thinking it's hard to deal with nuclear reactor ... but in my mind, this precise fact makes it UP. Windmills are OP if you compare EU-generation and cost to Solar Pannels, but setting up a windmill plant is just annoying, because you've to put it very high, so you need scaffold/cobble pillar while building, you've to use cable in the good way ...). Adding pollution would in this case buff greengen and nerf Fuel-based one, and even if Nuclear Reactors are currently not so much UP, basic Generator are. So I guess adding pollution would need buffing Nuclear (very little), Geogen (the same) and Generator (much more).
Display Moreuranium from sea water does not take that much energy, it can be selectively absorbed with certain fibers, from which the yellow cake (uranium ore) can be easily extracted. The main energy needed is for the pumps for flowing the water past the fiber. This is not the same extraction method used for hydrogen or many other compounds involving centrifuges, this is a much much cheaper and energy efficient method.
As for the being finite, with scrap you can already get an unlimited supply of most minerals, so that shouldn't be a concern. Stuff from ocean water is supposed to be practically unlimited anyway, just certain things are more difficult to extract.
As for determining if it is ocean water, you could do a check that it is in the right biome, then some sort of check for volume of water (when placing the extractor make sure there are more than a certain number of water blocks connected to the one it is extractring from, then have it only be able to use water it collects, not any other source of water)*. This way the only way to cheat it would be to build a giant artifical pond in an ocean biome, ie a waste of time.
*you could have it run a check on the block next to the water block it is placed in, make sure it is water, then check one next to that, and repeat for some large number. only if it is enough water will it allow the extractor to be placed at all.
The simplest way would be to ignore any of the above checks, and just have a biome restriction to ocean and beach biomes. and have the extractor not accept any other input besides the water surrounding it.
A possible mechanic for making the extractor more limited, would be to have it consume an extraction fiber, where different fibers can extract either specific or a range of specific materials, and take different times to do so. Then to make it more bulky you can have it require some large number of filled fibers to create a single piece of ore. also limiting the stack size of the unfilled fibers would then require a system to provide the extractor with fibers and remove the fibers when done. This would make it a bit more difficult to just have one machine that makes everything, like a high speed recycler turning cobble into anything you need.
Okay, I guess the method is good, and after checking the proportions of Ura in seawater, I guess it could be industrialized at a very high cost (ressources + EU/way of crafting maybe ?) But ... I guess if it should be implemented, others things should come before (ex way of getting Ura from Basalt/Lava/other mineral)
Quoted from "Hironimo"
As far as I can see it's needed to build a Matterfabricator and thus more iridum ore or other uu-matter stuff. It seemes it's needed in so much stuff in your mod .... I assume thats intentional?
It's configurable (you can disable a lot of things or enable a lot of others, as Matterfabricator recipes)
Display MoreTool boxes could be reworked to work like this :
It automatically stores all your tools inside and auto switches tools depending on your work
If you are using a non-toolbox tool it will be stored inside your inventory. If inventory is full, it will store it temporarily into the tool box until a slot of inventory is free.
Breaking stone like block : swap automatically to a drill or a pickaxe.
Breaking dirt like block : swap to a drill or a shovel.
Breaking wood like block : swap to chainsaw or an axe.
Breaking leaves like block : swap to chainsaw or a shears.
Attacking any entity (mob/player) : swap to an active nano saber, if not available, chainsaw instead or a sword.
Hold M and rightclick into any wrenchable block : swap to a wrench.
That's a good Idea, but it would seems strange punching a block with a .. ToolBox 
(and everybody know when wearing a Toolbox-like, we're very easy to kill, before placing the building :p)
--> it this case I suggest Tools non appearing if there's no empty slot in your handbar, so nothing happen, but if you've one, just click with it (so with nothing in your hands and the Toolbox in your handbar, the needed Item will automatically appear in your hand (as SpwnX suggested it). To change, just right click with it on nothing, and it will fill the Toolbox. To emptify (is it the right verb ? ^^) the toolbox, rightclick the ground (as it work now).
As far as i know Redstone is one of these Resources, which you ever have to much.
Unless your making tons of Solar Pannels. (I remember lacking of redstone while I was Solar Spamming (It's no longer right for me ) But ... it's always good nerfing undirectly Solar Pannels
And ... coding Seawater sources would change to many thing in my opinion.
It supposed to be an (current) endgame energy source. And if you want Infinite energy source, you also could use Grengen. And I see you decided to simply ignore my advice saying that it would be so energy-consuming to create Ura from seawater that you wouldn't get any energy benefit. (And for something very, very expensive in ressources.)
Is it possible to differentiate between ocean water from other sources of water? If so, then an alternate method of obtaining uranium would be to extract it from seawater. Currently it would cost about 10x more to extract from seawater than from mining. Maybe have a thing that can extract minerals from sea water (maybe some sorta thing to check that it is getting water from the ocean?)
This would provide an alternate way to get more of the elements you use.
What ? I could agree for Deuterium Tritium but ... Uranium is maybe contained in seawater, but I guess the exctracting price is SO expensive that you couldn't get energy profits even with using it in Nuclear Reactor ^^. At least, if you really want something that create energy out of nothing (or almost nothing), there's greengen/Fusion Reactor.
Feedback on the idea itself?
I would like it IF it comes with a buff of what can pollute. For 2 reasons:
1- Green gen are already OP if you use it during a VERY long time. I'm not against using 10-20 Solar Pannels to power machines (even if I think using Geogen is smarter at the beggining ^^), but using 100-2000 Solar Pannels to Power MassFabs ... that become annoying. So adding a pollution would make generator even worst because it would reinforce the "finite" aspects of those one. And as generator that could pollute are actually UP (I think about Generator, without Scaffold Glitch and without Adv Gen/ Gregtech addons :D), they would become totally useless.
2- Generally, players (and I also) dislike when something is nerfed. So it would need being nerfed (pollution) and buffed (Output, cost, energy value of fuels) at the same time.
I guess something like pollution could be implemented if something that makes generator very useful also is implemented, i.e. way of using fuel without wasting ressources (I mean using Coal in generator is quite stupid because you could also use Coal to get Carbon Plate/Carbon Dust). Alblaka already said that he will maybe implement a Gas-block later (and device for pumping it (and I hope device for refining, allowing higher energy profit), I guess it could go with Pollution.
Any suggestions?
Try to avoid mentionning the T-Word.
I has? I'm new.
EDIT: Used search bar, it hasn''t.
I tried with only 1 "l".
[Suggestion] industrial pollution
It was coded that way because I did NOT want to copy your casual "Item with own inventory for specific items"-concept. Though it's pretty much the only applyable concept nowadays, it seems
I'm fine with it. That's a way having ust 1 problem: the fact it's annoying when your inventory is full because it make you need to take the time to drop some items. But that also makes it different of all that Backpack and Alchemy bag from the mod I won't quote. Also, IC²-Toolbox is the only one not to be OP in my mind (because it can only store Tools, wich are unstackable, but don't allows you to get 2000 stack of cobble on yourself ...
I guess if the toolbox has been coded like that, it's maybe because it was easier ... but I agree with the Idea.
Hello, could you guys maybe add a slot so i can add transformer upgrades to induction furnace? It's kinda annoying that all my other machines are running hv but induction needs a transformer to run on my powergrid :s
First: the transformer upgrade need a transformer to be crafted so ... maybe your annoyed by space ? And adding transformer Upgrade for Induction Furnace would need slot, so it would need a additional line of code to avoid usage of overclocker upgrade in it ... But I can't see any reasons not to support this. I wouldn't use it but I support it.
Already asked ... use the LOSS-LESS MODE of the electric Wrench.
Melon. Easy to get. Do not mix IRL (In real life, so in Minecraft) and the rest, wich does not count.
Additional use for slime ball, since 1.4.2 I have a lot of slimes in the swamp near my base. (I though they were supposed to spawn closer to bedrock....)
I assume there is already one --> Slimeball to resin or something like that.
UU matter its a little like EE but only on the fact that you can choose what to make, you can't be precise on how many units you want to make nor you can make something with the bare minimum in most cases, its either all or nothing.
You forgot 2 main things: First: reaching endgame is faster with EE than with IC².
And more important: with EE you can turn ANYthing in ANYthing(else) you want. In IC², you can turn UUM in anything you want but you can't turn anything in UUM, so you can't turn anything in anything else.
