Can't you get wood from indoor mushrooms?
Yes, but it will require transporting water to the site we intend to use. I'll work on it later.
Our Power Plant is finished! It generates 4100 Kittenpower, and loses 530 to friction... so that's 3570 Kittenpower available.
Pumps need 10 power each, and I'll need at least 270 of them. That's 2700 power required for the pump stack.
That leaves 800+ power in reserve.
Notice those two green things in the power train, one just south of the Water Wheels, and the other adjacent to the (yellow) Pump Stack.
Those are "dry" pumps... pumps placed on land, where they can't pump anything. What is their purpose? The output end of a pump is treated as a solid wall. So I've placed and oriented those two "dry" pumps so that they can transfer power THROUGH the wall, without leaving a hole that someone could use to enter the Power Plant or the Pump Stack.
Naturally, this whole assembly is roofed in, so it is effectively a sealed unit. If for some reason it required servicing, I would have to deconstruct a wall to get in.
