Something I was thinking of after reading about someone's MFSU farm.

Personally I think the way to deal with energy beyond the 10M EU of a MFSU is to use it, but I gather some of you want to store the energy instead?

So...some ways to do this

Lapotron crystal silo:

I would anticipate using 4 retrievers to do this, might be possible to do it in 2 or even 1 and a sorter? The system consists of a charging section, a storage section and a discharge section. Retrievers move the crystals around. It should be possible to put 4 chests round each tube in the storage so a very high density is possible, especially if diamond chests are used.

Water cell silo:

I'm not sure how well this would work, it depends if the electrolyzer has distinct input faces for the two inventory slots (allegedly electrolyzed cells are bottom face, all others are water cells), as if it doesn't (like some industrialcraft bits) then probably the only way to route cells correctly is to ensure it never gets empty of either water cells or electrolyzed water cells.

It would suffer from a slow charge rate but the storage would be very cheap compared to lapotrons.

Oil or Lava Silo

Well the obvious problem with oil is turning it back to EU afterwards, I have no experience of Buildcraft engines but I gather they blow up frequently.

Lava is easy, though inefficient. Remember this is power you'd lose otherwise, so don't worry that the lava costs more EU than it gives back.

Storage could consist of a tank farm (remembering to include the wooden pipes and engines to extract the liquid).

Or...

You could pour it out into a big hole in the ground somewhere...more on that later.

Anyway this stuff is just ideas right now, anyone likes the idea maybe I could make a tutorial?
