Item #: SCP-1803-JP
Object Class: Safe Neutralized
Special Containment Procedures: SCP-1803-JP is currently stored in the research reference room at Site-81██.
Description: SCP-1803-JP is a black metal cube, 80cm on each side. A lever-shaped one-way switch that can toggle ON/OFF is installed in the top corner of SCP-1803-JP. Two silver metal rods, 1cm in diameter and 15cm in length, are placed at 25cm intervals near the top center. Sample collecting and component analysis have currently not been accomplished as the metal comprising SCP-1803-JP has extremely high hardness. Attempts to investigate its internal structure have failed as well.
When the switch on its top is toggled to "ON" side, SCP-1803-JP activates to generate electricity from its metal rods; it produces ███V alternating current between the metal rods, and can output approximately 100kW of electricity at the maximum. Notably, SCP-1803-JP maintains a constant power generation until it is turned off, despite the complete absence of external fuel or power supply. In an experiment before the long-term observation project (see below) was implemented, it was observed to operate continuously for up to 365 days, with no anomalous events occurring during that period.
SCP-1803-JP was discovered on 1986/██/██ by a demolition contractor during the deconstruction of a residence in the city of ████████, ████ Prefecture, Japan. The owner of the residence, a self-proclaimed inventor, is confirmed to have died of illness on 1984/██/██, at the age of 65. While SCP-1803-JP was attached with a sheet of paper describing it as "Perpetual Generator" upon discovery, the documents recovered from the residence provided no information regarding SCP-1803-JP.
Addendum 1: On 1987/██/██, Dr. ██████, who was responsible for the study of SCP-1803-JP at the time, proposed a long-term operation and observation project of SCP-1803-JP. His intention was to keep SCP-1803-JP in operation continuously for several decades in order to research the perpetuity of it. In parallel, a proposal was submitted to utilize the electricity generated as auxiliary power source for Site-81██. Both proposals were approved; the long-term observation project was launched on 1988/01/01 and is still ongoing. was terminated on 2018/01/01 with the neutralization of SCP-1803-JP.
Addendum 2: SCP-1803-JP ceased to function on 2018/01/01. Following subsequent investigation, it was reclassified as Neutralized on 2018/01/05 and has since been stored as research material. A partial record of the incident is attached below.
Incident 1803-JP: Video Log - 2018/01/01
Note: The footage was captured by a surveillance camera, showing SCP-1803-JP attached to the power generation unit in Site-81██, as well as the installed electricity meter.
<Log Start>
[00:00:01] The electricity generated by SCP-1803-JP begins to drop. Researcher ███, who was responsible for monitoring, confirms the irregularity.
[00:00:10] The electricity amount reaches 0 kwh. Researcher ███ starts to move toward the power generation unit.
[00:00:25] A square slit (a subsequent measurement confirmed that each side is 75cm) appears on the side of SCP-1803-JP.
[00:00:26] SCP-1803-JP vibrates violently. Following this, SCP-1803-JP trembles every few seconds, and the slit part lifts up each time. A yellowish-green glow leaks out from the slit. A muffled sound similar to a scream begins to be heard intermittently, gradually growing louder.
[00:00:45] Researcher ███ arrives at the power generation unit and approaches SCP-1803-JP.
[00:00:47] The side of SCP-1803-JP is blasted off, and a high-pitched scream is heard simultaneously. Researcher ███ is surprised and braces himself.
[00:00:49] A sphere emitting a intense light emerges from inside SCP-1803-JP, collides with Researcher ███'s abdomen, and disappears.
[00:00:50] Researcher ███ clutches his abdomen and crouches on the floor. A square metal plate is dropped beside him.
<Log End>
Following the neutralization, the internal structure of SCP-1803-JP was revealed.
SCP-1803-JP is made of 2.5cm thick metal, and has a hollow structure with a square space of 75cm on each side inside. A 25cm long bicycle was collapsed in the center of the inner space with its chassis and spokes deformed. The rear wheel of the bicycle was equipped with a hub dynamo, and electrical wiring had been run from the hub dynamo through the floor and sides to the top metal rods and other parts; the rear wheel could be rotated by fixing it with a stationary stand. The bicycle and hub dynamo were small but elaborately designed, and it was confirmed that electricity can be generated by rotating the bicycle pedals. It should be noted that the pedals would require a calculated ███ revolutions per second to generate the power that SCP-1803-JP was providing.
The following items were also found in the inner space.
- A 50cm long wooden miniature bed, snapped in half.
- A futon sized to fit the miniature bed, torn and spilling out cotton.
- A miniature television, with a destroyed CRT and a bent indoor antenna.
- A yellowish-green light emitting diode embedded in the ceiling. It can be switched ON/OFF using the external one-way switch of SCP-1803-JP.
- Battery installed at the end of a wiring branch from the hub dynamo. Power source for the miniature television and light emitting diode.
All of these items are presumed to have been destroyed during Incident 1803-JP. On the interior surface of the metal plate that was blown off during Incident 1803-JP, multiple footprint-shaped depressions about 4cm in length corresponding to a barefoot humanoid were present.
Mechanism explained. But one mystery remains… - Researcher ███
