Le programme de frontière
Quoi construire ensuite, et la mesure qui tranche.
Ce site existe pour former celles et ceux qui bâtiront la suite : les futurs ingénieurs de la fusion, les ingénieurs de la propulsion par distorsion, les expérimentateurs du plasma et du vide, et les métiers qui les entourent. Chaque fiche est une chose qu'une personne pourrait entreprendre : ce qu'elle propose, les résultats publiés sur lesquels elle repose, l'expérience ou la construction qui la mettrait à l'épreuve, sa place sur l'échelle de maturité, et le nombre qui trancherait. Prenez une fiche, réalisez sa mesure décisive et publiez la réponse, quelle qu'elle soit.

Puiser dans le champ du point zéro

The quantum-energy-teleportation cell
Build a small array of entangled two-qubit cells that release usable energy at one end when a measurement result arrives from the other end over an ordinary wire. Nobody pumps the ground state locally, because the ground state forbids it; instead one side measures, pays the energy cost of measuring, and sends a single bit that tells the other side exactly which operation unlocks the energy already sitting there as a suppressed fluctuation.

The geometry-tuned Casimir cell
Stop choosing materials and start choosing shapes. The force the vacuum exerts across a gap can be turned down about tenfold or up about threefold using nothing but the surface pattern, with the same metal and the same air.

The switchable vacuum rotor
Build a nanoscale motor whose only power supply is the vacuum, with an ordinary electrical switch on the front. Two recent results give the two halves: a voltage that flips the Casimir force from attraction to repulsion, and a magnetic field that switches on a Casimir torque between surfaces that carry no built-in direction at all.

The real moving boundary versus the electrical one
Settle an open disagreement between two people building vacuum-energy hardware. One argues that every existing dynamical Casimir experiment cheats — the boundary is moved electronically, never physically — and wants to move real walls along a tapered cavity so that different sections carry different mode counts and the device has a time structure built into its shape.

The Moddel cell and the thermodynamic ledger
Take the most advanced vacuum-power hardware claim in the field and settle it the way hardware claims are settled: independent fabrication, independent measurement, published artefact analysis. The device is a metal-insulator-metal tunnelling diode — palladium and nickel about two nanometres apart — with a Casimir cavity on top, so the vacuum inside the cavity is thinner than the vacuum outside.

The Casimir force at nuclear separations
Follow the vacuum force down from the hundreds of nanometres where everyone measures it to the femtometre gap between two protons, and see what it does there. Two recent papers take that step and find the force is not negligible at nuclear separations: the zero-point energy in such a gap corresponds to an enormous effective temperature, that fills the gap with electron-positron pairs, and those pairs screen the vacuum force into the same mathematical shape nuclear physics writes as the short-range nuclear potential.

Aneutronic fuel and the compact machines that suit it
Burn proton and boron-11 instead of deuterium and tritium. The reaction gives three helium nuclei and 8.7 million electronvolts with no neutrons in the main channel, so the products come back as charged particles you can convert straight into current instead of neutrons you must shield against and whose damage limits the life of the machine.

The sheared-flow Z pinch and the repetition problem
Revive the simplest fusion geometry ever drawn — run a large current straight down a column of gas and let the column's own magnetic field squeeze it, with no external magnets and no auxiliary heating — by fixing the instability that killed it in the 1960s. Give the column a sheared axial flow, faster on the axis than at the edge, and the kinks stay suppressed.

Fusion by field conditioning rather than by heat
Every fusion machine ever built spends most of its input energy overcoming electrostatic repulsion by brute force — heat it, squeeze it, or accelerate it. A different family of proposals asks whether the form of the electromagnetic field the nuclei sit in changes the effective interaction, so that less input energy is needed for the same reaction rate.

Warp Factory on a laptop
For thirty years warp drives were argued about on paper: somebody proposed a metric, somebody else did the algebra for one class of observer, and the argument continued. There is now a numerical toolkit that takes any metric, solves Einstein's field equations on a grid, and reports the energy density, pressures, momentum flows and energy conditions that metric actually demands — sampled across every observer rather than one.

Look for somebody else's warp drive

The superconducting gravity bench — an emitter and a mirror
Build the two components gravitational-wave engineering has never had: a laboratory source, and something that reflects. Both proposals run through the same physics — a superconductor is ordinary matter in which an enormous number of electrons move as one coherent quantum object, which is why it is the one material where a coupling to gravity might be large enough to use.

Condition the field, not the power
Ordinary electromagnetism couples to gravitation far too feebly to be useful. The conditioning programme says the weakness is not about how much energy you put in but about the form the field takes — give an electromagnetic field a structure closer to the one underlying gravitation and the coupling gets much louder.

The reversal test
Before any propellantless thrust claim can be believed, the field needs a shared instrument and a shared protocol. That protocol exists, it is published, and it is unglamorous: turn the thruster around inside the vacuum chamber without opening it, and see whether the force turns around with it.

Settle the inertia correlation function
The 1994 result that inertia is a Lorentz force exerted by the zero-point field on accelerating matter has a specific, published technical objection, and that objection names its own resolution. The dispute comes down to a single mathematical object: which correlation function actually describes zero-point radiation as seen by a uniformly accelerated detector.

Angular acceleration, not rotation rate
The rotating-superconductor gravity experiments have a thirty-year replication problem, and one specific parameter has never been systematically varied: the rate at which the disc is spun up. If the effect depends on angular acceleration rather than on steady angular velocity, then every replication that ramped gently was testing the wrong variable, and the thesis's own emphasis on acceleration transients — rather than speeds — says exactly that.

The analogue-gravity bench
Curved-spacetime physics genuinely emerges from ordinary matter in a laboratory. Push a fluid past its own speed of sound and waves inside cannot fight their way back out; the sound field then obeys exactly the wave equation of a massless field on a curved metric assembled from the fluid's density, flow speed and sound speed.

Build a Nachamkin plasmoid on purpose
There is a family of solutions to Maxwell's equations, in a partially ionised gas, that behaves like electromagnetic energy trapped in a ball and holding itself together — with a calculable critical frequency and calculable resonant sizes at which the object exchanges no energy at all with its surroundings. Nobody has built one to the specification and measured it.

Make ball lightning and instrument it
Long-lived luminous balls can be produced on a bench with an ordinary electric arc, and one natural example has been caught in spectrum. The subject therefore has everything it needs to stop being a collection of stories: a laboratory recipe, a natural measurement, and a growing structured observation channel cross-checked against professional lightning-location data.

The EVO crater — two accounts, one micrograph

A 2022 paper from a former Naval Research Laboratory materials physicist offers a conventional account of the same craters.

Calibrated sky, not footage
Every argument about anomalous objects in the sky is really an argument about instrumentation. A passive electro-optical or infrared sensor cannot supply range, so a size and a speed derived from one camera depend entirely on an assumed distance.

Adopt, publicly and as a matter of course, the two disciplines that decide whether any energy claim in section 2 means anything.

Isotopic forensics
Make it standard practice to open the device afterwards and ask what the material became. A stray impurity arrives with its ordinary isotope ratio, so a ratio that is wrong points at a nuclear process rather than at contamination — which makes isotope mapping the single most decisive after-the-fact measurement available to this field, and one that modern instruments can now do point by point across a sample.

Listen for gravitational waves far above the band the big interferometers cover. Nothing in the known astrophysical catalogue is small and dense enough to ring at megahertz to gigahertz, so anything found there is new physics — and, for this site specifically, that band is exactly where the laboratory emitter proposals of section 3 would radiate.

If a cavity changes electron-phonon coupling, then it changes the screening energy
Two settled facts have never been put in the same room. First: an unpowered resonator placed near a superconductor changes its transition temperature, and first-principles calculations trace the effect to the vacuum field reshuffling how electrons trade energy with lattice vibrations.

If Planck's constant measures the field's density, then find the test that separates it from the fine-structure constant
One strand of this subject holds that Planck's constant is a measure of the zero-point field's energy density — deeper ocean, larger constant — and that changing the density changes the vacuum's permittivity and permeability and therefore the local speed of light. The people who hold that view also state its own falsifier plainly, and it is a sharp one: measuring the fine-structure constant alone cannot detect any of this, because its terms compensate, so a null result on the fine-structure constant is not evidence either way.

If entanglement is the vacuum's fuel line, then the cell array has a scaling law
Quantum energy teleportation is the only route to ground-state energy that has been run on hardware, and the accounting stays ordinary throughout: the measurement pays. Everyone therefore treats it as a curiosity rather than as an energy technology, and stops.

If a plasmoid is vacuum-coupled, then its lifetime tracks the boundary around it
The central puzzle of section 5 is lifetime: laboratory plasmoids last microseconds and the objects this site is interested in are reported to last minutes. One reading of the thesis is that a long-lived plasmoid is coupled to the vacuum — that its boundary modulation and its energy source are the same thing.

If the zero-point field carved the voids, then the void edges carry its fingerprint
One published model says the zero-point field does something visible at the largest scale there is: because the field's spectrum looks identical from every moving frame there is no drag to damp its kicks, so an isolated proton in near-empty space slowly gains energy, the emptiest regions are energised most, they push outward, and they compress their surroundings into sheets until trapped magnetic fields lock the structure. If that is right, then the foam of voids and walls redshift surveys actually show is a zero-point-field signature, and it should differ in a specific, statistical way from the structure gravity alone would build.
