The Reactor is the core technology of the Belluaire Component. It is the object that couples to the activated medium, resonates at the key signature, and drives the Load that the Collector converts to electricity. Every other part of the Component exists to support it.
Throughout this book, the Infrasonic Reactor is called the Reactor. The Infrasonic Reactor +Source is called the +Source — it is understood that the +Source is always a Reactor with the Source coupled to it. In contexts where both are discussed, the full name Infrasonic Reactor +Source is used to avoid ambiguity. These prose forms are used everywhere except in formulas or technical specifications, where the abbreviations IR and IR+ may appear.
The Reactor has five sub-parts: the Resonator, the Pedestal, the Tuning Mechanism, the Load, and the Load Bearing Mechanism. Each is described below, followed by the assembly that holds them together.
The Resonator is the oscillating element of the Reactor. It is the part that swings.
The Resonator is ferromagnetic. This property is required because the Source drives it by magnetic force — a pair of complementary semi-circular electromagnetic coils, alternating, pulling the Resonator first one way and then the other. A non-ferromagnetic Resonator would not respond to the Source.
The Resonator has a hole opening at its very top. The Pedestal passes through this hole. The hole and the Pedestal have matching profiles — once the Pedestal is inserted and fastened, the Resonator is completely locked to it. There is no slipping and no independent motion. The Resonator and the Pedestal move as one body.
The Resonator’s geometry and material determine its natural frequency. Its dimensions set the frequency at which it swings; its material purity determines how long it sustains that swing once driven. These are design variables, chosen to match the key signature of the Source.
The Pedestal is the support structure of the Reactor. It is the part that holds the Resonator and transmits the driving force to it.
The Pedestal is lowered into the Altar, which seats in the Platform opening. It extends downward through the Altar and the Platform into the chamber beneath, where its shaft rests in the Seat and connects to the Tuning Mechanism. Above the Platform, it passes through the hole at the top of the Resonator and is fastened there by the Load Bearing Mechanism.
The Pedestal is more than a rigid support. It is a spring. It deforms under asymmetric load and returns to its unloaded shape when the load is removed. This elastic behaviour is essential to the Reactor’s operation: it is the restoring force that prevents the inverted pendulum from falling, and it participates in the oscillation as a frequency-selective element.
The Pedestal also provides the freedom required for the Resonator to swing. A bevel in the Pedestal confines this swing to a single axis — a flat, back-and-forth motion in one plane. This constraint is not incidental: the Collector hovers in a fixed position above the Load and depends on the Magnetic Interface sweeping a predictable, repeatable arc in that plane to maintain reliable magnetic flux coupling. If the Resonator were free to rotate or wobble around other axes, its swing would drift off that fixed arc and the Collector would lose coupling. The quality of the bevel determines the minimum friction loss in the oscillation cycle.
The Tuning Mechanism is the part that adjusts the Reactor’s frequency. It seats at the bottom of the chamber — the opening under the Platform that houses it.
The Tuning Mechanism connects to the Pedestal. By raising or lowering the Pedestal along its axis, it changes how much of the Pedestal projects above the Platform. That change in exposed length alters the Resonator’s swing profile — its effective pendulum length and the distribution of mass about its pivot — which in turn shifts its resonant frequency. A shorter exposed Pedestal produces one tuning; a longer one produces another.
The mechanism never touches the Resonator itself. It changes the geometry the Resonator swings from.
In the Belluaire Component’s own design, this adjustment is electronic and continuous. Built-in sensors read each Resonator’s actual tone in real time, and a controller compares that reading against the target frequency, calculating the deviation introduced by constant vibration and wear. It then drives the Tuning Mechanism to raise or lower the Pedestal by whatever amount returns the Resonator to its ideal tone. The loop runs continuously, holding every Reactor in the array at its designed frequency despite drift that would otherwise accumulate over hours or years of operation.
The Load is the part of the Reactor that interfaces with the Collector.
The Magnetic Interface is the magnet assembly at the Resonator’s crown. As the Resonator swings, the Magnetic Interface sweeps through an arc. The Collector’s coils are positioned along that arc, and the changing magnetic flux through them induces the electrical output. The strength of the Magnetic Interface determines the output voltage per unit of Resonator velocity.
The Load Bearing Mechanism is the structural fastener at the crown of the Reactor.
It fastens the Pedestal, the Resonator, and the Load into a single moving body. The three elements are held as one rigid unit; the Load Bearing Mechanism is what makes the crown of the Reactor act as a whole.
The five sub-parts assemble into a single functioning unit. The sequence is:
The result is a Reactor: a ferromagnetic Resonator, suspended on an elastic Pedestal, mounted in an Altar at the Platform level, its shaft grounded in the Seat, tuned by a mechanism in the chamber below, carrying a magnetic Load at its crown, free to swing at its natural frequency, and ready to be driven into sympathetic resonance by the activated medium.
