Mechanism and Primitive Description
The disclosed primitive is a transportable Flash Joule Heating assembly that converts locally sourced carbonaceous biomass, agricultural residues, forestry waste, coffee grounds, rice hulls, urban green-waste, construction-site woody debris, into turbostratic graphene at the point of structural pour. The unit comprises four functional subsystems: (i) a pair of discharge electrodes defining a feedstock-confinement geometry within which the FJH event occurs; (ii) a capacitor-bank energy-storage subsystem dimensioned to deliver the millisecond-scale current pulse that raises feedstock temperature beyond the graphenization threshold; (iii) a feedstock handling subsystem comprising hopper, comminution, conductive-additive blending, electrode-cavity loading, and post-flash output collection; and (iv) a credentialed signing module that attests the feedstock-to-graphene conversion event with cryptographic provenance.
Operationally, prepared biomass is fed into the discharge cavity, mechanically or electrically pre-conditioned to the conductivity range required for ohmic-resistive heating, and subjected to a high-voltage capacitor discharge. Joule heating drives the carbon matrix above approximately 3000 K within a sub-second window; volatile non-carbon species are expelled, and the residual carbon lattice reorganizes into a few-layer turbostratic graphene morphology. The product is collected, optionally further milled, and routed directly into the cementitious or polymer mix at the construction site.
The primitive is distinguished from a benchtop or pilot-scale FJH apparatus by three architectural features: transportability (skid- or container-mounted form factor with ruggedized power-conditioning), feedstock agnosticism within the local-biomass envelope, and on-board credentialing. The credentialed signing module records feedstock species, mass, location coordinates, energy delivered per discharge, and graphene yield per batch, producing an attestation that travels with the carbon into the structural pour. The lineage chain is therefore established at the site of incorporation rather than reconstructed downstream from shipping records.
Operating Parameters and Engineering Envelope
The mobile FJH primitive is bounded by parameters that follow from the underlying flash physics and the construction-site context. Discharge voltages typically sit in the 100 V to 400 V range for laboratory-scale work; the disclosed transportable embodiment scales the capacitor bank to deliver pulsed currents on the order of kiloamperes per discharge event, with per-batch feedstock masses ranging from grams to kilograms depending on cavity geometry. Pulse durations are on the order of 10 to 500 milliseconds, and peak temperatures exceed 3000 K to ensure transition to the graphenized phase rather than to amorphous char.
Feedstock preparation imposes its own envelope. Moisture content must be reduced to a level compatible with stable ohmic conduction, typically below 10 percent, and particle size must be reduced sufficiently for uniform packing within the electrode cavity. A conductive additive (typically a small mass fraction of carbon black or recycled flash-graphene fines) is blended in to bring bulk resistivity into the range that the capacitor bank can drive. The disclosed handling subsystem performs these conditioning steps on-site, removing the requirement that feedstock arrive in a pre-processed state.
Power input may be drawn from grid connection where the construction site has temporary service, or from the building's own substrate-mode storage in embodiments where the carbon-bound cell array is already populated and discharging during the carbon-incorporation phase. The latter configuration closes a small loop in which energy that the structure will eventually store is borrowed during construction to produce the graphene that enables the storage. Throughput is bounded by capacitor recharge time between discharges and by the duty cycle of the feedstock handling subsystem; nominal operating throughput is set such that graphene production tracks the rate of structural pour.
Environmental envelope includes ambient operating temperature, vibration tolerance during transit, dust-and-moisture ingress protection, and electromagnetic emissions during discharge. These constraints distinguish a deployable mobile unit from a fixed-installation FJH cell that need not survive transport or operate outside conditioned indoor space.
Alternative Embodiments
The disclosed primitive admits a range of embodiments differentiated principally by form factor, power source, and feedstock specialization. A skid-mounted embodiment occupies the footprint of a small shipping pallet and is craned into position adjacent to the structural-pour zone; a container embodiment is housed within an ISO intermodal shell and arrives by truck or rail; a trailer embodiment integrates the FJH unit with a generator and feedstock-storage volume on a single road-legal chassis.
Power-source embodiments include grid-tied, generator-fed, photovoltaic-and-battery-buffered, and substrate-mode-buffered configurations. The substrate-mode-buffered embodiment is of particular interest where the structure-under-construction has already received a partial complement of carbon-bound cells and can deliver the discharge energy from its own incipient storage. Feedstock-specialized embodiments tune the comminution and conditioning subsystems for a target waste stream, sawmill residue, agricultural straw, biosolid char, or municipal green-waste, without altering the core discharge architecture.
Further embodiments contemplate networked operation, in which a fleet of mobile FJH units is dispatched across a region and reports credentialed conversion attestations to a shared registry, and roving operation, in which a single unit moves between sites on a route determined by feedstock availability and pour schedule. Hybrid embodiments combine the mobile FJH primitive with stationary biomass pre-conditioning depots, where comminution and drying occur at a regional hub and the conditioned feedstock is delivered to mobile FJH units in batched form, preserving the on-site conversion property while consolidating the most energy-intensive preparation steps.
Composition with Adjacent Primitives
The mobile FJH primitive composes with three adjacent primitives in the carbon-substrate-flow family. First, it composes with the credentialed-feedstock-attestation primitive: the on-board signing module emits attestations in the same schema consumed by downstream incorporation and pour-record systems, so that the lineage chain crosses the boundary between conversion and incorporation without translation loss.
Second, it composes with the substrate-mode storage primitive of the carbon-bound cell family. When the construction is at the stage where some structural carbon already participates in storage, the mobile FJH unit may draw discharge energy from that storage rather than from the grid, closing a recursive loop between storage and conversion.
Third, it composes with the structural-pour-incorporation primitive: the graphene exits the FJH cavity, optionally passes through a brief milling or de-agglomeration stage, and enters the cementitious or polymer mix at controlled mass-fraction. Because pour and conversion occur within meters of one another and within minutes of one another, the incorporation primitive can rely on freshness and provenance guarantees that a long-distance supply chain cannot provide.
Prior-Art Distinctions
The disclosed primitive is distinct from the centralized FJH facility model in which biomass is shipped to a fixed conversion plant, graphenized at industrial scale, and the product is then shipped to construction markets. Centralized FJH benefits from economies of scale but inherits the long-distance transport, batch-aggregation, and provenance-loss problems characteristic of conventional carbon supply chains. The disclosed mobile primitive trades unit-scale efficiency for transport elimination, regional supply enablement, and on-site credentialing.
The disclosed primitive is also distinct from conventional carbon-additive supply (carbon black, expanded graphite, commercial graphene oxide), all of which arrive at the construction site with provenance fixed at points upstream of and disconnected from the pour. None of these supply modes admit a credentialed conversion event whose attestation is generated at the geographic and temporal coordinates of incorporation.
Finally, the disclosed primitive is distinct from prior on-site biomass processing (pyrolysis kilns, biochar units), which produce amorphous char rather than turbostratic graphene and which lack the cryptographic-attestation infrastructure that anchors the disclosed lineage chain.
Disclosure Scope
The disclosure scope of the in-situ flash graphenization mode under Provisional 64/050,895 covers transportable FJH apparatus comprising at minimum a discharge-electrode pair, a capacitor-bank energy-storage subsystem, a feedstock-handling subsystem, and a credentialed signing module configured to emit attestations of feedstock-to-graphene conversion events at the geographic coordinates of a structural-pour site. The scope encompasses skid-, container-, and trailer-form embodiments without limitation to a particular chassis class.
Power-source scope is open across grid, generator, renewable, and substrate-mode-buffered configurations, with explicit contemplation of embodiments in which discharge energy is sourced from the carbon-bound storage of the structure-under-construction. Feedstock scope is open across woody, herbaceous, residue, and waste-stream biomass categories, subject to the conductivity-conditioning envelope described above.
Credentialing scope covers any attestation schema that records feedstock identity, conversion-event parameters, geographic coordinates, and a cryptographic linkage to the downstream incorporation record. The disclosure expressly anticipates network embodiments in which fleets of mobile FJH units publish to shared registries and roving embodiments in which a single unit serves multiple sites along a feedstock-driven route.
Disclosure scope does not extend to fixed-installation centralized FJH plants, to non-credentialed mobile carbonization equipment lacking the signing-module element, or to on-site biomass processors that produce char rather than graphene. The boundaries of the primitive are set by the joint presence of transportability, flash-graphenization capability, and on-site credentialed attestation; the absence of any one of these elements removes a candidate apparatus from the disclosed class.
The disclosure further contemplates that the credentialed attestation is interoperable with downstream verification systems used by structural engineers, building inspectors, and carbon-accounting registries, so that the lineage chain established at the construction site is portable to the regulatory and commercial frameworks that consume it. Scope therefore reaches the attestation-schema layer in addition to the apparatus layer, and embodiments that emit attestations in formats consumable by such downstream systems fall within the disclosed primitive.
