格雷4避雷针的被雷批中概率计算以及输出功率计算

通过向避雷针的上方堆叠铁栅栏来获取雷电的能量.

在比较落后的版本中只要堆到256格高就会在下雨天气里获得电力.

新版本中必须被雷电劈中铁栅栏才能获取能量

要想使雷电劈中铁栅栏，铁栅栏必须堆到128高度以上。

铁栅栏每秒内被闪电劈中一次的概率=(铁栅栏高度-机器高度)×铁栅栏高度÷13421772.8

显然机器放得越低栅栏高度越高中概率越大

注意闪电劈没劈是GREG自己决定的，也就是用暮色传送门的闪电或者服务器命令的闪电劈中避雷针都是无效的

输出为8192eu/t

A Lightning Rod is a device which converts the power of lightning into usable EU. One lightning bolt will instantly be converted to 25,000,000 EU expelled at 8192 EU/t. The only way to be able to harness this vast amount of energy is with the help of 4 HV Transformers placed on the sides of the Lightning Rod.
避雷针能够将雷电转化成EU。一次雷击生成25,000,000 EU，按8192 EU/t输出。利用这些电力的唯一方法是用高压变压器。

Uses

The Lightning Rod gets power when lightning strikes it. The higher the Iron Fences structure reaches, the more likely it has a chance to be struck with a lightning. Only the length of the lightning rod affects the probability of a strike.  Building a lightning rod “net” will not make it more likely for a power generating bolt to strike.  The Gregtech mod only takes into account the iron fence blocks above the Lightning Rod block. Source Code Sn ippit.
避雷针在被雷击后得到电力。铁栅栏越高，概率越高。仅仅避雷针的高度影响概率。建造一个避雷针组不会提高概率。格雷mod仅仅考虑避雷针块上的铁栅栏块。

Lightning rod block emits EU from its sides at the rate of 8192 EU per tick. Out of all the machines, only the Matter Fabricator and the Fusion Reactor can receive power directly from it. For others, HV Transformers should be used.

The lightning rod has an internal storage of 25,000,000 EU. Each bolt of lightning that hits it will fill it completely. If there is a storm, and it gets hit multiple times, it will only store a max of 25,000,000 EU, so if you cant drain it fast enough, you lose the additional EU generated by subsequent strikes as it can only hold what its internal storage allows.

The Lightning Rod could be a very efficient way of gaining energy for mystcraft ages. Setting the age to be always stormy, would generate a lot of EU. The Mindcrack modpack however doesn't have Mystcraft, and the Direwolf20 modpack doesn't have Gregtech although you could add mystcraft/gregtech manually or switch to the Ultimate pack.

Trivia

According to the source code the effect is not actually triggered by lightning striking the rod. Instead, it calculates a random number, and checks if this number is below (Rod_Length * Top_Of_Rod_Height).

If that is the case (and there is a thunder storm at the moment), it generates an artificial lightning bolt that strikes the rod. Then the charge is set to 25.000.000. If a real lightning bolt would hit the rod, nothing would happen.

Using other mods to create more lightning bolts won't do anything. What does help, though, is to use mods that set the weather to thunder storm, since the Lightning Rod needs a thunder storm to do anything at all.

If one is willing to live with the negative side-effects, the Dragon Egg Energy Siphon and the Lightning Rod can be used for effective generation of power: The Energy Siphon will inevitably produce huge amounts of Flux. As a result of this, a message about Flux altering the weather will appear quite often, causing a thunderstorm and thus setting excellent conditions for lightning strikes on the Lightning Rod. Note though that the frequent lightning strikes directed at the player are a huge downside, plus they cannot be used for power generation.
