A water wheel is a machine component that provides power via water flow. To build a water wheel, select build menu and choose Machine components. It requires 3 wood and generates 100 power, which can be used for operating a pump or mill. Use axles and gears to access the power produced by a water wheel.


Construction

Intuitively one would place a water wheel in a river, but they can also be powered if placed over brook tiles, but only if you first dig through the surface of the brook. Designate at least a single tile for channeling (dh), right on the brook. The water wheel will sit above this channel, but you cannot place it yet -- it must have a support first. Horizontal axles, gear assemblies, screw pumps, and supported water wheels are all capable of supporting a water wheel, even if the construction of the support isn't finished. Should a water wheel lose its support, it will instantly deconstruct.

Power will be generated once a tile under the water wheel is filled with water at a depth of four or greater. You can transport the power wherever it is needed via horizontal and vertical axles and gear assemblies.

In order for the water wheel to generate power, there needs to be a water flow in one of the three tiles beneath it.

This is by no means the limit of water power from one location, depending on the width of your river/brook/channel you can stack many waterwheels side-by-side (really big assembles will need to be artificial as there's a limit to how wide the game created water flows get). Just remember to make sure there's a support structure in place before you place the next wheel.

Perpetual motion

Due to the low power draw of a screw pump, a self-powering assembly can be made with a water wheel that still leaves plenty of excess power for other uses. This is an exploit, and possibly a bug.

A simple design is available at this forum post.
