Revision as of 08:28, 8 June 2008

I've not used waterwheels yet, so I'm unsure if this is the case, but couldn't you, theoretically, set up a perpetual motion machine using a waterwheel and a screw pump?


The article contradicts itself, it says on the first line "in" a flow, but the next line refers to a flow underneath, which is correct? Matryx 17:34, 31 October 2007 (EDT)

A perpetual motion device is easy enough to setup once you have an understanding of screwpumps and power. I currently have a water wheel placed between two underground resevoirs that runs a mill and pumps water from the lower tank to the higher one. Its very energy efficient aswell. Three axles, a gear, the mill and the pump only draw 40 power leaving me 60 for other devices.

I'll try get up screenshots of it or maybe a tidier one later --Lucid 19:58, 31 October 2007 (EDT)


Someone removed my edit, but the water wheel actually only requires one square of water underneath it, not three. - Sludge Man

We could really use better pictures. The tileset in these screenshots is terrible, (lets use the default one) and they are very unclear. I do not understand how to build a working waterwheel after looking at this page.

I removed the unclear example of a perpetual motion machine with a forum link to much clearer designs. We still need clear pictures and elaboration of the method of construction. I'll get around to it once I understand it myself, if no one beats me to it. --Turgid Bolk 15:48, 5 November 2007 (EST)

Sorry about the tilesets but I didn't think anyone would mind my custom one considering the only noticibly difference is the pump which looks like 2 barrels.

Although my screenshots were specifically for a perpetual motion machine which is why they lacked indepth wheel and pump construction. I was hoping to create a video or some sort of tutorial to add in the construction section which dealt with creating waterwheels for someone who has absolutely no idea of any of the mechanics.

Also how reliable are the new designs? I checked out that link and I previously toyed with designs similar to those and found them to be excellent power generators but not true perpetual motion machines, they all lost power intermittedly for varying lengths of time. --Lucid 18:30, 5 November 2007 (EST)

Perpendicular to water flow

Strange as it may sound, water wheels do 'not' need to be parallel to the water flow direction to work. VengefulDonut 16:31, 23 November 2007 (EST)

This is as in real life - you can build a less efficient water wheel by putting the "buckets" at an angle - and indeed might put the "buckets" on a 360 degree pivot for some purposes.GarrieIrons 07:21, 8 January 2008 (EST)

Water Flow Needed?

Actually there is no need for water flow at all. A water wheel seems to generate power even if it is built to a water body with no current (no "entry" or "exit" points). So basically the water wheel just needs to touch water and that's it. This is what I've noticed when confining a canal with floodgates at both ends. --Flaa 07:47, 22 April 2008 (EDT)
This seems to have changed in a recent version. In previous versions you just had to connect a canal to a brook and the whole canal would count as 'flowing' even when nothing was moving. In my latest game this hasn't worked. So it's either changed, or the fact that I tried a 4-tile wide canal has stopped it working. --Juckto 18:22, 10 May 2008 (EDT)

Powering a Water Wheel

It seems that you can connect a Water Wheel to a Windmill, or other power source and cause it to spin - is there a purpose to doing this? can you move water along channels this way? What are the benefits? --SeiferTim 12:47, 12 March 2008 (EDT)

I think that it's because water wheels use power to run. Hence, they produce 100 power by themselves, but end up using 10 to spin, making the net power output only 90. Therefore, most likely the windmills provide that 10 power to the waterwheel. I don't think it does anything, but it does look cool.

Verify Carpenter

Does the water wheel require carpentry to build?--Richards 04:11, 21 April 2008 (EDT)

Yep--Dorten 04:15, 21 April 2008 (EDT)
Thanks Dorten.--Richards 04:26, 21 April 2008 (EDT)

Minimum water level

What is the minimum water level and flow required to power a waterwheel? --Sphexx 16:48, 27 May 2008 (EDT)

Definition of "flow"?

The article states that waterwheels need flow under them, but how exactly does the game calculate this?

I was thinking that it means any water changing depth below it, but that would rule out building on a river/ocean full of 7/7 tiles. Will a waterwheel work on top of water full to the brim but supposedly "flowing" (i.e. ocean, full river)? G-Flex 04:28, 8 June 2008 (EDT)

I believe that right now a waterwheel will provide power as long as there is at least 4/7 water depth below it, or at least that is what has been the case in my experience, as I don't think a dead end channel would really provide any water flow yet a waterwheel will still provide power if place over one. --Elvang 04:15, 8 June 2008 (EDT)
Are you sure, though? Juckto (above) seems to believe the state of affairs is a bit more complicated. I guess I can just test it out for myself at some point.
