World Accelerator

World Accelerators (WAs) are singleblocks that can accelerate the tick rate of blocks around them using EU. World Accelerators come in eight tiers, from LV to UV, with higher tiers taking more power but providing a greater speed boost and covering a larger range. World Accelerators support two modes, which can be toggled with a screwdriver. In Normal Mode, they can only accelerate simple blocks (non-tile entities), will consume up to 3 amps of their tier, and have a large cube-shaped area of effect centered on the World Accelerator. In Tile Entity Mode, they are able to accelerate tile entities (with the exception of GregTech machines), but consume 6 amps of their tier and can only affect the 6 blocks directly adjacent to them. World Accelerators above LV can also be decelerated by right clicking them with a GregTech wrench, which allows underclocking to any lower tier, with each underclock halving the speed and quartering the power usage. Multiple World Accelerators can be applied to the same block, with a roughly additive effect.

In Normal Mode, World Accelerators have a very large area of effect, but cannot accelerate tile entities (any block with complex data, including everything with an internal inventory). Although the tooltip describes their range as a "radius", in reality World Accelerators work in a cube centered directly on them, with a side length of ${\displaystyle {\displaystyle 2\times {\text{Radius}}+1}}$. It is possible to decrease the operating range of a World Accelerator by shift-right clicking it with a screwdriver, which will also decrease its power usage. When doing so, the power usage is given by this formula (the tier is based on the acceleration factor, not the tier of the block):

${\displaystyle {\displaystyle 3\times 1{\text{A}}_{tier}\times {\frac {{\text{Range}}_{curr}}{{\text{Range}}_{max}}}}}$

The following table compares the efficiency of each tier of World Accelerator at default settings in terms of EU per extra tick, both in optimal conditions where the entire range is used, and in a simpler scenario where only one layer of blocks can be accelerated, such as saplings in a tree farm or a single-layer crop farm.

Most of the interesting blocks to accelerate are tile entities, so the main use of a World Accelerator in Normal Mode is to accelerate non-IC2 crops, especially Thaumic Bases crops such as Sweed, Redlon, and Rainbow Cacti, before the Extreme Industrial Greenhouse is available.

• Tree of Time Sapling - another source of tick acceleration through the Timewood Clock.

In Tile Entity mode, World Accelerators are able to accelerate almost any block in the game, with a few exceptions such as GregTech machines and OpenComputers devices. It is much more useful than Normal Mode, especially due to its ability to accelerate non-GregTech machines to keep up with the processing demands of lategame, but this power comes at the cost of using twice as much energy (6 amps instead of 3) and being restricted to only accelerating its six neighboring blocks, rather than the hundreds or thousands available in Normal Mode. Some notable uses for World Accelerators in this mode include:

• Apiaries, largely to speed up the process of manual bee breeding, but also for certain bee effects like the Empowering Bee.
• IC2 Crops, also to speed up manual breeding.
• The Blood Altar and Alchemic Chemistry Set from Blood Magic.
• The Thaumatorium (next to the central block) and Infusion Altar (next to the Runic Matrix) from Thaumcraft.

Since World Accelerators use quite a bit of power, they should usually be toggled by a Machine Controller Cover to prevent them from drawing power when the blocks to be accelerated aren't active.

Higher-tier World Accelerators than IV should not be used in Normal Mode, since multiblocks like the Extreme Industrial Greenhouse or Tree Growth Simulator can accomplish the same tasks with better performance and power usage.
