Tesseracts will output up to 1 bucket per tick, per side, if my memory serves me correctly. The problem you will most likely run into is that liquiducts may only transfer 160 millibuckets per tick per side. 5 sides of a tesseract will need to be used to take steam from a full size boiler, and the output tesseract will also need 5 sides in use unless directly touching some machine.
Well, I was just going to put the tesseracts directly next to the boilers, so this shoudln't be a problem right?
Also: is there a limit to the amount of liquid that can pass through an ender tank at once? If not then i'll probably just use them.
EDIT: Well, it seems i've got another problem. I've got my first 36hp boiler going, but for some reason its only producing 80 mb of steam per tick. Can anyone think why? Its getting plenty of fuel and water.
EDIT AGAIN: Apparently liquid tesseracts got severely nerfed, they can only accept up to 80 mb/t of stuff. Looks like i'm using ender tanks...
EDIT AGAIN AGAIN: It seems evem ender tanks can only handle 100mb/t. Sod it! I'll have to place the bloody power converter on the boiler itself.
EDIT AGAIN AGAIN AGAIN: Even putting the steam consumer next to the boiler doesn't solve the problem. Looks like i'm using industrial steam engines...
