CONSTRUCT THERMAL BOREHOLE sB RATE 24
A thermal borehole is a shaft driven through the crust of Planet to tap direct-
ly into the geothermal energy and rare mineral resources of the inner core. A
thermal borehole yields +6 minerals and +6 energy, regardless of terrain type.
No other enhancements except roads and mag tubes may be built in the same
square as a thermal borehole, and they can only be built on land.
Requires Ecological Engineering.
DRILL TO AQUIFER Q RATE 18
This command taps into a subterranean fresh-water source and brings it to the sur-
face. The new water source immediately begins to flow to the sea, creating a river.
Requires Ecological Engineering.
TERRAFORM UP ] RATE 12
You can raise the elevation of a square, raising surrounding squares propor-
tionately, to create a natural slope. Terraforming up can increase energy pro-
duction in the region and also provide a natural barrier to trap atmospheric
moisture (see Energy/Elevation, p. 38), increasing rainfall on the windward
slope and decreasing it on the downwind side. It can also be used to build land
bridges by raising the sea floor.
Requires Environmental Economics.
TERRAFORM DOWN [ RATE 12
You can lower the elevation of a square, dropping surrounding squares pro-
portionately. Sea formers can lower coastal squares below sea level, turning
them into ocean shelf squares (this is done by lowering an ocean shelf square
to make it an ocean square—the slope created causes adjacent coastal squares
to drop below sea level). This destroys any enhancements and units in the sub-
merged area, as well as any bases not protected by a Pressure Dome facility.
This option can be used to destroy land bridges.
Requires Environmental Economics.
