Gear assemblies take up a single tile and transfer power to any device, axle or gear assembly within the six orthogonally adjacent tiles (north, south, east, west, above, below). Gear assemblies are best used for moving power through right-angles. For example, they can be built as bases for windmills to move power out sideways along an axle. Gear assemblies can also be linked to a [[lever]] to disengage them, which will stop power transfer through that tile. Don't do this with gears that are supporting machinery above them, as the machinery may collapse. | Gear assemblies take up a single tile and transfer power to any device, axle or gear assembly within the six orthogonally adjacent tiles (north, south, east, west, above, below).

− | Because of the high power use of gear assemblies (5), axles are more appropriate and convenient to build when transferring power across horizontal or vertical distances. An axle uses (1) power for every tile of power transfer. An axle 5 tiles long will use (5) power. Axles can be directly attached to windmills, waterwheels and screw pumps in order to provide power. | + | Because of the high power use of gear assemblies (5), axles are more appropriate and convenient to build when transferring power across horizontal or vertical distances. An axle uses (1) power for every tile of power transfer. An axle 5 tiles long will use (5) power. Axles can be directly attached to windmills, waterwheels and screw pumps in order to provide power. For security, one can make an axle-train cross a moat by first going down the moat, across, and then up. Or perhaps a screw pump will make a floor-type security-wall for a downward axle. |
Devices that use power are also capable of transferring it. Adjacent screw pumps will transfer power between themselves. The only way to prevent this is to leave a tile gap between devices, or move them diagonally from each other. | Devices that use power are also capable of transferring it.

Single-tile rollers transfer power in all four cardinal directions. Rollers transfer power perpendicular to their direction and ''may'' transfer along their direction (it's unreliable). | Single-tile rollers transfer power in all four cardinal directions.

− | Rollers need 1 rope and | + | Rollers need 1 rope and exactly as many mechanisms as an axle would need wood; they also may be built individually up to 10 tiles long, but have only the horizontal variant. Rollers consume 2x more power per tile than axles and need more materials. But they aren't used to connect along their direction anyway, and axles don't transfer perpendicularly on their ow. When compared to axles ''combined with gear assemblies'', rollers are good. |
