Wind Mills are Generators that utilize the energy of the wind to produce EU. They are the most unstable and unpredictable type of generators, depending greatly upon both placement and pure luck.

Usage[edit]

Optionally place an RE Battery in the upper slot. The Wind Mill will charge the battery or output power at a rate of 0-4 EU/t depending on placement.

Detailed Mechanics[edit]

  • A Wind Mill will produce on average 250 EU per Minecraft day multiplied by its height in the world.

This number varies greatly due to the highly unpredictable and constantly changing wind strength in the world; this number can be anything from 0 to 1000 EU. (Although numbers far below 150 or far above 320 are uncommon )

  • A Wind Mill's efficiency can be hindered by any kind of block placed in a 9x9x7 area around it.

It's best to have the cable from the Wind Mill underneath it and down at least two blocks before turning.

  • For each obstructing block, a Wind Mill's effective height lowers by 1.
  • A Wind Mill treats non-block items like torches and Redstone wires as obstructions too.
  • A Wind Mill doesn't treat the roof of the world as an obstruction.
  • Wind Mills produce 50% extra EU/t in a thunderstorm, and 20% when it's raining but not in a thunderstorm.
  • If a wind mill produces more than 5 EU/t, it has a chance of breaking. If a wind mill's effective height is no more than 80, it cannot break.

Examples[edit]

  1. A Wind Mill placed as high as possible (layer 256), with no obstructions (apart from the 2 cable blocks under the wind mill) will produce roughly 63500 EU (250 * 254) a day or 2.6 EU/t overall.
  2. A Wind Mill that was placed near bedrock (layer 10) with no obstructions (not including the cable again) produced 2000 EU (250 * 8) a day (0.1 EU/t overall).

Wind Strength[edit]

  • Minimum strength is 0, Maximum is 30.
  • Modified every 128 ticks (About 6.4 seconds)
  • Chance to increase or decrease by 1.
  • 10% chance to increase if current strength is 0 to 20.
  • 10% chance to decrease if current strength is 10 to 30.
  • Current strength of 0 to 9 have (current strength)% chance to decrease in strength. (E.g. 0 current strength has 0% chance to decrease, 1 = 1% to decrease, ..., 9 = 9%)
  • Current strength of 21 to 30 have (30 - current strength)% chance to increase in strength. (E.g. 21 current strength has 9% chance to increase, 22 = 8% to increase, ..., 30 = 0%)

Power[edit]

  • Calculated every 128 ticks (About 6.4 seconds)
  • Minimum power is 0, Maximum is 11.46 (y: 255, obstructions: 0, and thundering), Maximum safe is 4.98 (y: 147, obstructions: 0, and thundering). Maximum safe, with 2 cables, is 4.98 (y: 149, obstructions: 2, and thundering). Maximum safe, with 2 cables, is y = 191 if you wish to ignore high wind and rain storms.
  • Calculation is: power = s * (y - 64 - c) / 750; 's' is Wind Strength, 'y' is Block Height, and 'c' is number of blocks (not including the windmill itself) in a 9x9x7 area around the windmill.
  • Power has a 50% (* 1.5) increase if it is thundering, 20% (* 1.2) increase if it is raining.
  • If the power is higher than 5, there is a 0% to 0.1292% chance (chance based on power) to change the windmill to a generator and drop 0 to 4 iron ingots.

Height and Copper Cables with Wind Turbines[edit]

As of Dec 2012, height ~y=140 gives 50-70% turbine effectiveness.

If using Copper Cables, it is necessary to place Batboxes usually within 4 blocks, serially, from the wind turbine, in addition to having Batboxes every 10 x,y or so to keep the current boosted; Batboxes negate the EU reduction over distance.

Use the EU meter to see how much the turbine produces and how much EU there is in the cable, from the turbine later in the circuit. The current read from the turbine itself will be how much there is being delivered to the network after the Batbox, placing the Batbox closer to each turbine can increase it drastically. Here is an illustration. "

Ensure that the Batbox OUTPUT (Dotted side) is pointed the right way, and always check each turbine individually throughout the circuit.


HAYO[edit]

As well, you can create these nifty daylight-independent Windmills for an all-over-the-day constant energy supply.

Now, it's not THAT constant, as wind strength may change, globally. But hey, in general it will produce a steady supply of energy.

Sometimes, with good wind, it will even produce more then 11 times the power of a Solar Panels! ALL OVER THE DAY, HAYO!

Our company is fully aware of all placement problems regarding Windmills.

Windmill efficiency WILL drastically reduce if not placed high enough, or obstructed by many other blocks in a 5 block radius.

We are fully aware that high wind speeds may damage Windmills.
