Windmill tower calculation check

1st Official Post

    Hello guys,


    i have created an Excel Spreadsheet to calculate how many energy can produce a windmill farm.


    So here is the hypothesis :


    - The tower is made of 8 stack of wind mills. far enought from each other to not interact with the nearby stacks.
    - Each stack is a straight cable pointing to sky, and leaving at least 2 cables under the last wind mill with nothing on it.
    -the first layer of each stack always start at the layer 128.


    -top view of a stack


    ....:Wind Mill:
    :Wind Mill: :Cable: :Wind Mill:
    ....:Wind Mill:


    -Side view of a stack (for exemple a stack with 3 layers, it can be more or less, that's the point of the calculation ....)


    :Wind Mill::Wind Mill::Wind Mill:
    :Wind Mill::Wind Mill::Wind Mill:
    :Wind Mill::Wind Mill::Wind Mill:
    ....:Cable:
    ....:Cable:
    ....:Cable::Cable::Cable::Cable::Cable:


    and now here are the maths : for exemple a stack of 15 layers of windmills




    explanations of how it works.


    layer wind mill : this is the Y position of a layers of wind mill
    wm above : the amount of windmills above the concerned layer in a max range of 4 block according to the behavior of the wind mill.
    wm under : idem, but range max 2b and we must count the 2 cables at least if = 0.
    obstruc : the amount of obstructions. 4 for the layers itself (the windmill isn't a obstruction for itself and i count the center cable). 5 obstruc for each layers above or under the concerned layers. and eventually the minimum of 2 blocks of cable under the stack.
    energy (for ONE layer and for one day/night cycle) : 250*4*(layer-obtructions)
    total : total of all the layers.
    "for tower ub eu/s" typo fail here. i mean the total in eu/s for 8 stacks. so (total*8 )/24000



    e.g. for a layers .


    layer 125 as 3 layers of mills above (126,127,128 ) and 2 layers of mill under (125,124) so the amount of obstruction is : 5+5+5+4+5+5 = 29 obstructions.


    energy outut for this layers is 4*250*(125-29) = 96keu for one day. (so 1eu/s for each mill (96k/(4*24000), still logical). (IT'S OVER NINE THOUSANNND)



    Infine, this post has 2 purpose. checking the calculation and sharing the idea. so what do you think of this ? :)

    Very nice windmill setup, suddenly they seem like a worthy opponent to solars :]


    In actual usage, you'd need to either use fibre cable or batboxes (then the number of layers is limited by the 32 EU/s output of the batbox) or LV-transformers between every 3 4 layers (max output 128 EU/s) or tin cable once it's fixed.

    That was my intention when I remade them :D

    Lesson 1: Watch over your crops....

    After some calculations:


    In a wind-tower with 32 layers or less, every windmill (by average) makes more energy per iron used than a solar.
    (I counted 10 iron for a windmill and 6 iron for a solar)
    1 layer - 1.525 times more
    2 layers - 1.462
    4 layers - 1.35
    8 layers - 1.228
    16 layers - 1.13
    32 layers - 1.005


    If it's more than 95 layers high (more like deep), the total energy produced decreases with every additional layer.

    Does anyone have a saved file of an example of a really packed in area or even video screenshots etc? Right now this is how I generate power:



    This is the most efficient way I could think of generating power. But if you think I can save resources and Build as much per area or near that would kick ass.

    I'm pretty sure it would be an impossibility to make it any more compact and efficient. I used the same design on an old map and currently have plans to do it once more on my map now.

    For the same amount of energy you'd need for example: 8 towers, 13 layers each, fibre cable inside them, spaced 6 blocks between cables and built from the top of the world. It's just a question if you prefer large, flat solar arrays or tall windmill towers :)

    Or both :p there is only 20 blocks without sun on the tower area, this mean you can hit more than 512 eu/s during the day and 350-400 during the night with a tower of 17x17. where you need a 23x23 area with full solar for 512 at day and 0 at night.


    and yes, this is uselless unless you want a huge uu matter production or powering an entire town in smp ^^

    I was just messing around and designed a layout for a 27 x 51 solar array (using just tin cables). It did have some gaps though (so only 1359 panels .. which would need to be connected to a HVT *boggles*).
    I think I could do better, and possibly make it square... Ed: Looks like I can do 39x39.. Ed2: Still Gaps [1499 panels..]
