A '''Sleep accelerator''' is [[miscellaneous]] building added by the [[Ideology DLC]]. It increases the rate at which a pawn sleeps, giving them a longer working day, in exchange for increasing the amount of nutrition they require and consuming power. 

== Acquisition ==
Sleep accelerators can be constructed once the [[Research#{{P|Required Research}}|{{P|Required Research}}]] research project has been completed. They require {{Required Resources}}, {{Ticks|{{P|Work To Make}}}} of work, and a [[{{P|Skill 1}}]] skill of {{P|Skill 1 Level}}. Sleep accelerators can only be constructed by colonists with an [[Ideoligion]] containing the [[Ideoligion#Transhumanist|Transhumanist]] meme.

== Summary ==
[[File:Sleep accelerator all placements.png|thumb|left|Every valid placement and rotation of the sleep accelerator. Note that only one accelerator can be active for a bed.]]
Sleep accelerators can be installed to a bed, granting +35% [[Rest Effectiveness]] and +20% [[Saturation#Hunger Rate Factor|Bed Hunger Rate Multiplier]] to the colonist sleeping in it for 400W power. Note that this Rest Effectivenes bonus is applied before the quality multiplier on Rest Effectiveness of the bed, that is the bonus is multiplied by the '''bed's''' [[Quality#Structures|quality (Rest Effectiveness Factor)]]. It is applied ''after'' the multiplier from being a bed being made of stone. It takes 50W power when it's not being used. 

As noted by the description, the sleep accelerator must be placed adjacent to and facing the head of the targeted bed to have effect. More than one accelerator has no effect. A [[double bed|double]] or [[royal bed]] only requires a single accelerator to affect both pawns.

The following beds can utilize the sleep accelerator: {{#ask: [[Facility::{{PAGENAME}}]]}}.

'''Nota bene:''' As the rest effectiveness bonuses apply to the bed ''before'' the bed's [[quality]] multiplier is applied, the exact bonus the sleep accelerator applies scales with the '''bed's''' quality.

Pawns with a Transhumanist ideoligion will gain a {{+|3}} [[mood]]let for 24 hours whenever they sleep with a sleep accelerator.

== Analysis ==
=== Costs and benefits ===
{{For|full analysis of rest and sleep saved|Rest}}
When sleeping in a normal quality [[bed]], sleep accelerators will save 1.4 hours of sleep per day (5.8% of a day). In a masterwork bed, this is reduced to saving 1.25 hours (5.2% of a day). While this might seem paradoxical, considering the accelerator's increased Rest Effectiveness, using a masterwork bed means that there's less sleep need to be saved. In both cases, sleep is reduced by roughly 20%.

Consequently, other means of sleep reduction, like [[psychite tea]], [[bionic heart]]s, [[circadian assistant]]{{RoyaltyIcon}}, or the [[Genes#Low sleep|Low sleep]] gene{{BiotechIcon}}, will all reduce the relative impact of the sleep accelerator. However, with multiple means of sleep reduction, pawns will start to go well "beyond" a 24 hour sleep cycle. In this scenario, setting their [[schedule]] to all Anything will reduce the time pawns travel to and from bed, increasing efficiency in a different way.

The power draw is significant and spikes while colonists sleep. If a pawn sleeps for 6 hours a day and [[batteries]] are used, then an average of roughly '''{{#expr: (300*6/15) + 50}} W per day''' if said power is constantly supplied. Batteries will only store 50% of any excess power. So if [[solar generator]]s are used while colonists sleep at night, then more power is required, up to the upper limit of {{#expr: (300*6/12) + 50}} W per accelerator. The hunger cost can largely be counteracted by growing more food, or by using a [[nutrient paste dispenser]]. <!-- 50 W all day. +300 W for 6 hours = 1800 W hr. Batts store 50% energy when stuff is offline. 6 hours online, (18 * 0.5) effective hours offline, or 15 effective hours a day. 1800 W hr / 15 hr = 120 W average, plus +50 W all the time, assuming chemfuel generator.-->

=== Should you build? ===
Overall, the sleep accelerator is a permanent {{+|5%}} or so buff to colonist time, once you can afford the resource and power cost. However, most players should consider these buildings with the entire Transhumanist package. In addition to being happy from accelerators, transhumanists will demand [[neural supercharger]]s at moderate [[expectations]] (80,000 colony [[wealth]]). Once high [[expectations]] (180,000 colony wealth) are reached, [[biosculpter pod#Age Reversal|age reversal]] will also be demanded.

* Neural superchargers are another power- and resource- hungry machine, requiring {{Required Resources|Neural supercharger}} and consuming {{Q|Neural supercharger|Power Consumption}} W all day. For the entire day, the supercharge gives {{+|10%}} [[Consciousness]], boosting a wide variety of stats, along with {{+|25%}} [[Global Learning Factor]]. However, pawns will be more hungry, in addition to the power cost.
* Age reversal takes a minimum of 2.61 days/year, or 4.31% of the year when tuned in a [[sterile tile|sterile]] room. In a regular, clean room, this takes 3 days/year (5% of the year). This negates most of the benefit from the sleep accelerator, and comes with the downside of pawns unable to exit freely without [[Ailments#biosculpter sickness|biosculpter sickness]].
If your colony has not reached high expectations yet, or the {{--|4}} to {{--|10}} moodlet from no age reversal is taken, then the accelerator and supercharger are a maintenance-free positive to work. If pawns are getting age reversal, then sleep accelerators are a ''very'' slight positive to work (though you'll get the full benefit from the supercharger).

=== Tips ===
* Pawns in a [[double bed]] will share a sleep accelerator, so you may want to pair pawns up. Manipulating their actions, using the "Romance" option in the Social tab, and/or using the Word of Love [[psycast]] can all help power. If you're using solar generators, then you may want to have pawns sleep in the day in order to ignore the battery's 50% penalty and use the generator's full draw of power. If you are doing this, remember that [[light]] impacts both movement and work speed.
* If another faction has the Transhumanist ideoligion, then you can have their pawns construct sleep accelerators and neural superchargers without your entire colony demanding accelerators/superchargers/age reversals/body parts. This is also possible with a fluid ideoligion, though development points can be somewhat prohibitive.
** If your faction is against Diversity of Thought, then you can [[arrest]] the other ideoligion pawn as soon as they are done building them, and put them in [[cryptosleep]] until you need more fancy buildings built.
