Connections[edit]

Performance penalty for colonists working in another connected dome is 10 (source: NonHomeDomePerformancePenalty).

Water[edit]

Basic Dome[edit]

A basic dome requires 10 polymers. That the equivalent of 20 waters.

It allows you to build a water spire at the cost of 40 Cement, 20 metal and 10 polymers, as well as the spire slot and workers working full time, 3 if they can work at 200%. When fully staffed, the dome will cost only 0,3 water per hour, or 7,2 per day.

It will take the spire 28,5 hours to return the water it costed to produce it's polymers. Considering it's sizable Cement and metal investment, it's not worth spamming in all basic domes. It might be worth it in domes where food is produced.

Barrel Dome[edit]

The barrel dome requires 20 polymers that is produced from 40 water. It has the same water consumption as the basic dome, if no spire is used, it provides 86 hexes instead of 60, an increase of 43%.

2 Barrel domes would have 172 hexes while 3 Basic domes would have 180 hexes. Running at two water instead of three, the two barrel domes would return the increased water that was required to produce its 40 polymers instead of the 30 polymers of the three basic domes in less than a sol, and from there run at higher efficiency.

Metal[edit]

  • 2 Barrel domes have 172 hexes
  • 3 Basic domes have 180 hexes.
  • 2 Barrel domes cost 40 metals
  • 3 Basic domes have 60 metals
