EARTH LAUNCH COST

Carbyne is a one-dimensional chain of carbon atoms. Pure sp hybridisation — alternating single and triple bonds, or cumulated double bonds. Theoretical tensile strength twice that of diamond. The only material that cuts nuclear corium. The boring tooth that goes through the Elephant's Foot. The wiresaw that sections reactor cores. Manufactured at L4 from asteroid carbon in zero-G vacuum — the only environment where carbyne synthesis works correctly.

The Material

One Carbon Atom
After Another

Carbon has three hybridisation states: sp³ (diamond, tetrahedral), sp² (graphene, planar), and sp (carbyne, linear). Each step up the hybridisation ladder increases bond strength and reduces dimensionality. sp is the theoretical limit. One-dimensional. Linear. Absolute. The carbon atoms in carbyne are linked in an unbroken chain with no branching, no defect sites, no cross-linking. The chain is the structure. There is nothing else.

DIAMOND HARDNESS
Theoretical tensile strength exceeds diamond by a factor of two. At the current limit of carbon bond mechanics. No harder material exists.

GPa YOUNG'S MODULUS
Three times stiffer than diamond under compression. Resists deformation at pressures that shatter any other material.

°C SUBLIMATION
Carbyne does not melt — it sublimes. The highest thermal stability of any carbon allotrope. Operational in reactor environments that destroy all other cutting materials.

PURE HYBRIDISATION
Every carbon atom in pure sp hybridisation. No sp² defects. No branching. No amorphous contamination. Zero-G CVD synthesis at L4 achieves this purity consistently.

POLYYNE / CUMULENE
Polyyne (alternating single-triple bonds) is semiconducting. Cumulene (cumulated double bonds) is metallic. Phase selected by CVD process parameters at L4.

ONLY CORRECT SYNTHESIS
On Earth, carbyne chains collapse to graphite under gravity and atmospheric contamination. Zero-G vacuum CVD at L4 grows perfectly aligned isolated chains. Not a preference — physics.

The Application

The Elephant's
Foot Won't Cut Itself

Reactor 4 sub-basement. 200 tonnes of corium — melted uranium oxide, zirconium, graphite, and structural steel fused into a silicate glass ceramic matrix at temperatures exceeding 2,000°C in April 1986. Now solidified. Now intensely radioactive. Now sitting in the dark for 39 years waiting for a machine that can cut it and a chip that can survive long enough to run that machine. The corium ceramic is harder than any conventional cutting material that has ever been sent into that room. Diamond tools attempt it and fail — the radiation environment destroys the tool's bonding matrix before the cut is complete. Tungsten carbide wears in minutes. The corium is not the problem. The tools are.

Radiation transparency: Carbyne is a pure carbon allotrope. sp hybridised carbon has no metal binder, no polymer matrix, no ceramic bond phase — none of the components that conventional cutting tools use and that radiation destroys. The chain is carbon. The radiation cannot attack what is not there. Carbyne boring teeth and wiresaws operate in the Chernobyl sub-basement for the duration of the mission. The corium is sectioned. The drone completes its task.

Industrial Cutting Products

Boring Teeth.
Wiresaws.
Nothing Else Cuts This.

Carbyne cutting products from Speculāris are manufactured for one class of customer: those facing materials that no other cutting tool survives. Nuclear corium. Depleted uranium ceramic waste forms. High-level waste glass matrix. Spent fuel assembly cutting. If the material is harder than diamond and the environment destroys conventional tooling, carbyne is the answer. There is no alternative.

Replaceable boring tooth insert for TBM cutterheads, core drill assemblies, and rotary boring systems. The CBT insert seats in a standard carbide seat geometry — direct retrofit onto any existing TBM or core drill that uses replaceable disc cutters or button inserts. The carbyne cutting edge replaces the tungsten carbide insert. No drill modification required. Designed for C1 Scout drone spectrometer-tip core drills and C2 Operations drone boring systems in the Chernobyl remediation programme.

Corium penetration rate limited by drive torque, not tool hardness. The carbyne insert does not wear on corium contact. Replace on schedule maintenance interval, not on failure.

Chernobyl Remediation — Cutting Sequence

How You Cut
the Elephant's Foot

01
C1 Scout Mapping — Define the Cut Plan
DRAD-1 equipped C1 Scout drones enter the sub-basement. NIR/UV spectrometer maps the corium mass geometry, composition, and temperature distribution. Full 3D model generated. 87 container-sized section boundaries computed. CBT and CWS tool selection per section based on local hardness data.
02
CBT Boring — Penetration and Relief Holes
C2 Operations drones equipped with CBT series boring teeth drill relief holes at section boundary intersections. The CBT boring teeth penetrate corium ceramic at full drive torque — no tool wear on corium contact. Relief holes reduce stress concentration for the wiresaw cut. DRAD-1 monitors torque and feed rate continuously.
03
CWS Wiresaw — Section Cuts
C3 Slicer drones deploy CWS wiresaw between relief holes. Micron-scale kerf — minimal contamination spread. Full section cut through 200-tonne corium mass at container-boundary lines. Cut sequence proceeds from exterior inward — each completed section removed before the next cut begins.
04
Container Loading — 87 Containers
C2 Operations drone manipulator arms load each section into a shielded container. RFID-tagged. Sealed. Logged in DRAD-1 asset tracking system. C4 Transport drones remove containers to surface staging. No human entry required at any stage.
05
Switzerland → Sun — Permanent Disposal
Containers transfer by rail through Austria to the Swiss Alps mass driver. Solar intercept trajectory. The Sun's gravity captures each container. 200 tonnes of corium — permanently removed from Earth. Chernobyl is clean. The carbyne cutting tools made it possible.
Manufacturing

Made in Zero-G.
From Asteroids.

Carbyne cannot be synthesised correctly on Earth. Gravity causes growing chains to sag and contact neighbouring chains. Atmospheric contaminants attack the sp hybridisation. The result is collapse into graphite or amorphous carbon. Zero-G vacuum CVD at L4 is the only correct synthesis environment. Factory 3 Line 3C. Asteroid carbon feedstock. Zero raw material cost.

☄️
Asteroid Carbon Feedstock
C-type asteroid 2020 XL5 — 40–45 million tonnes of carbon. CVD precursor methane synthesised from asteroid CO₂ via Sabatier reaction. Zero Earth launch cost for production feedstock. The raw material is free.
🔬
Zero-G CVD Synthesis
Chemical vapour deposition in L4 zero-G vacuum. No gravitational sagging of growing chains. No atmospheric contamination. Pure sp hybridisation achieved consistently. On Earth this is physically impossible at production scale. At L4 it is routine.
💎
Phase Selection
CVD process parameters select polyyne (semiconducting) or cumulene (metallic) phase. ChemLab 2 XRD verifies phase purity. Boring teeth use polyyne — maximum hardness. Wiresaw uses controlled cumulene/polyyne composite for toughness optimisation.
🏭
Factory 3 Line 3C
Same production line as CVD diamond optical elements and DRAD chip substrates. Carbyne synthesis is a dedicated process step on Line 3C. DRAD-1 controlled deposition parameters. Quality certified by ChemLab 2 before each product batch ships.
🧲
CNT Composite Integration
Wiresaw core uses CNT composite wire — same Factory 3 Line 3B product as FPP coil windings. Carbyne abrasive bonded to CNT composite core. Result: wiresaw with carbyne hardness and CNT tensile strength. The two hardest materials at L4 in one product.

Delivery FOB Earth Orbit

The Hardest Thing
on Earth Cannot
Cut the Corium.

Diamond is the hardest naturally occurring material. The Elephant's Foot is a silicate ceramic fused at 2,000°C containing uranium oxide, zirconium oxide, and graphite in a glass matrix. Diamond tools fail on it — not from hardness, but because the radiation destroys the bond matrix before the cut finishes. The corium has been waiting for a material that is harder than diamond and transparent to radiation.

That material is carbyne. Two times harder than diamond. Pure sp carbon with no binder, no matrix, no component for radiation to attack. Synthesised at L4 from asteroid carbon in the only environment where the synthesis works. Manufactured. Certified. Delivered. The Elephant's Foot has met its match.
