Generator using Cobblestone and Scrap

what scrap makes energy?

what scrap makes energy?

870 EU per piece. I think this is either a new or underused function of scrap, but that's kind of impressive that you got the setup to work in such a way like this...

Nerf Cobblestone? lol

I never knew that scrap could be burned.... If you had Equivalent Exchange then you might be able to directly convert cobble to coal some how. On the other hand, that is completely random. Have you reached ignition? How much energy does this make?

Some math:

One recycler uses 1 eu/t and takes 35 ticks per recycling operation.
That means it takes 280 ticks per scrap produced, on average, and consumes 280 eu to do so.
870 - 280 = 590 eu
590 eu over 280 ticks = 2.107 eu/t, which is more than most renewable generators.

Because a generator burns a piece of scrap in 87 ticks, but a recycler takes 280 ticks to produce one, you will need at least one generator for every 3.218 recyclers.

From 3.218 recyclers (which take 10 iron to make) and one generator (which takes 8 iron to make) you will get 6.780 eu/t, and spend 40.18 iron ingots. That's 0.1687 eu/t/iron ingot.

From solar, you get about 0.5 eu/t from 10 iron. That's 0.05 eu/t/iron ingot.
From wind, you get up to 1.3 eu/t from 12 iron. That's 0.108 eu/t/iron ingot.
From unmanned water, you get up to 0.25 eu/t from 4 iron. That's 0.0625 eu/t/iron ingot.
From manned water, you get up to 2 eu/t from 4 iron. That's 0.5 eu/t/iron ingot.

Conclusion: This gives you cheaper power than any other simple renewable source, other than manned watermills.

Thought I should add: I tried this in SMP once, before this topic, but I ended up losing energy overall. I think I got the balance of the various parts wrong then - not enough recyclers to offset the fact that I was making cobble pipes as scrap fodder, which costs energy to macerate and smelt the cobblestone.

Since you're obviously using RedPower for the block breaker, you can do away with the obsidian pipe and just run a brass tube from the back of the block breaker into the top of the recycler.

Ow, before people start spamming this on servers:
This setup is VASTLY more CPU expensive then any other mean with equal energy generation. Don't kill your server by building hundreds of these contraptions please, killerbeez will either kill me or bug me to mod something against that.

This actually already happened on mine. At one point I actually had to prevent lava from flowing to stop these lag machines from making the server unplayable. Thankfully, I have the help of someone who can program and now have found a more elegant solution (making recycling cost much more EU and making block breakers have a 20 second minimum waiting period between operations). I'm not sure if this would be as much of an issue on peaceful servers though. Why go through all the trouble of making this contraption when you can just plop some wind or solar gens down? The only reason my people used them is so they could get the unlimited energy deep underground and in secrecy.

I think this problem should be easly solved through the nice redstonepowered water-generators which were posted today or yesterday in teh forum. Because you can use it deep underground and it brings a lot of EU/t.
So thx to the guy who posted this water-generator-system.

Can somebody post on which kind of generator is most CPU efficent? And I just make wind and water as to use ALL the energy sources. All you really need is solar.

You can hook the Blockbreaker up to a buffer then pump it out using buildcraft redstone engine

Or a chest. Why do people keep involving buffers in things when they're not needed?

They reason they a buffer would buffer better than a chest, even though chests actually buffer better than buffers. Bufferering!

I was JUST saying that the 'Buffer' needs to be renamed, as it doesn't work as advertised. It should be called the 'Consolidator' or some such rubbish. What we need is a 'filter -> chest -> filter but-all-in-one-block' PROPER buffer! Just a filter with some internal storage for incoming items when it's backstuffed.

Sort of like this one?

I choose buffers for simplicitys sake, I mean you don't actually have to use a buffer your can use any kind of containter(e.g. chest etc..)

verry verry nice

il build this one in my experimentation world and look at how fast an MFSU gets filled with 10 of these
