Cities and homes on vacuum power

The capability we assume

Assume the endpoint, because the endpoint is what the people building this are aiming at.

Every building here carries a sealed device that draws steady power out of the vacuum. No fuel line, no flue, no tank, no bill, nothing delivered. It is the domestic form of the free-energy chip — the thing Ashton Forbes describes in its consumer version as a chip in your phone that runs forever. Harold "Sonny" White states his Casimir power cell's target as power density comparable to a solar cell, except that the cells combine in parallel and in three dimensions. Stack them and a cupboard runs a house.

That is on the bench now, in three funded programmes with hardware: Garret Moddel's asymmetric optical and Casimir resonator at Colorado Boulder, White's Casimir power cell, and Charles Chase's asymmetric resonant tunnelling diode at the UnLab, where electrons tunnel through a barrier they should not get through and pull the zero-point energy with them. Chase's summary is that all three are one idea: create an asymmetry in the vacuum, then use it to do work, force or current. Underneath them sits settled physics — the Casimir force, measured to about one percent by 1998, and Wilson and colleagues in Nature in 2011 turning vacuum fluctuations into real photons.

The first door into that reservoir is fusion, opened from the vacuum side. NASA Glenn published real nuclear reactions inside a deuterated metal lattice in Physical Review C in 2020 — published and peer-reviewed — because a lattice screens charge and lowers the Coulomb barrier locally. The barrier is an adjustable parameter, not a wall. The fuel that matters is aneutronic, proton and boron-11: charged particles you convert to current directly in a coil, with no steam, no turbine and nothing to shield. Chapter 6 and the zero-point field and Casimir course teach all of it.

The second capability is the same knob turned the other way. If inertia is the vacuum's reaction to acceleration — Haisch, Rueda and Puthoff, Physical Review A, 1994 — then modifying the local vacuum reduces effective inertia, and a craft with reduced inertia and no reaction mass hovers, accelerates hard and makes no sonic boom. Salvatore Pais holds a US Navy patent for that device. Ashton's line is the one to hold: extract zero-point energy and you get energy, and you also get motion. Chapter 8 teaches the craft; Chapter 4 and the metric tensor course teach the geometry.

Silence in the basement, silence in the sky.

First-order effects

Every building makes its own power and heat, forever. Lights, warmth, cooling, hot water, the lift, the cooking — in any weather, at night, in a blackout that never comes. The grid stops being the artery and becomes a sharing layer.

Comfort stops being bought. Warmth, cool, hot water and filtered air become defaults the way tap water is: nobody weighs heating against groceries, because there is no bill.

The fire goes out of the home. Billions of households still cook over open flame and breathe the smoke. A flameless hob on a sealed cell ends that, in every house, permanently — the most immediately life-saving thing on this page.

The street goes quiet. Field drive carries no reaction mass and burns nothing, so the two loudest things in a city — combustion and the road built for it — go. A street sounds like voices, footsteps, birds.

Anything can be built anywhere. The hardest part of housing was never the house: it was the substation, the main, the sewer and the road. A building that brings its own power, treats its own water and takes freight from the air needs only land and consent. A farmhouse, an island and a city flat end up with identical services.

Second-order effects

Location stops being priced by connection. Land is expensive largely because of what is already plumbed and wired to it. When power, heat, water and delivery arrive with the building, that premium evaporates and the map of where it makes sense to live is redrawn.

Housing cost falls to materials and labour. With the energy term gone from making the materials, moving them and running the building, what remains is the stuff and the people who assemble it — and, as manufacturing shows, unlimited energy makes recovered steel, glass and aluminium the cheap option.

Density and greenery stop competing. No pylons, substations, fuel depots or filling stations, and roads shrink to what people and quiet freight need. Roof gardens and glasshouses cost nothing to condition, so a dense street can also be a green one.

Public buildings come back. Libraries, swimming baths, halls and covered markets were built in great numbers and then closed, and running cost is what killed them. Free heat, light and water make civic generosity affordable again — the effect people feel first in their street.

Third-order effects and beyond

The city stops being an import machine. For two centuries urban form has been dictated by getting fuel in and waste out: the coal wharf, the gasworks, the power station, the ring road, the pylon line. Each is a consequence of energy being expensive to move. Remove the cause and the deepest organising principle of the modern city lapses. What replaces it is whatever we choose — which has never once been true before.

Architecture is released. The sealed, low-ceilinged, small-windowed building of the last fifty years exists because volume costs money to condition. High rooms, courtyards, glass roofs and generous stairs come back within reach of ordinary housing.

The ground comes back to people. A car-shaped city spends a huge share of its surface on roadway and parking. Quiet field-drive movement needs almost none of it, and that reclaimed ground is this world's gift to children, to old people, and to anyone who ever wanted to sit outside their own front door.

And the far frontier opens under the city too. Chapter 4 teaches that the metric — the rulebook setting how long a ruler is and how fast a clock ticks — is a physical object that mass and energy already rewrite every second. Puthoff's programme is titled Advanced Space Propulsion Based on Vacuum (Spacetime Metric) Engineering. A civilisation with a vacuum device in every basement will ask what else can be written into that rulebook, and it will ask early.

A day in that world

Hector wakes at six because he always has, and the flat is already warm.

That still gets him. He grew up waking into cold, dressing fast, hearing his mother say the word for the bill in a particular tone. Now the sealed unit by the stairwell has hummed for eleven years and nobody thinks about it any more than the drains.

He makes coffee on a hob with no flame. Out the window the street is grey-blue and silent: a woman crossing with a dog, two children on a doorstep, plane trees, and where the parking ran, raised beds and a bench. He can hear a blackbird four floors down.

At half seven he climbs to the roof to water the tomatoes. The glasshouse is warm and smells green and wet. Six of the eight flats grow something up here.

He works at the baths. They reopened when the running cost stopped existing, in a building shuttered since before he was born, and there are ninety children in the water on a school morning.

At lunch he sits outside. A freight pod settles onto the roof of the shop opposite without a sound, lifts again, and is gone over the river. Nobody looks up. His granddaughter cycles down the middle of the road, and neither of them thinks about it at all.

Numbers that change

The size of the reservoir under the floor. Eric Davis's comparison table puts dark-energy density at about one nanojoule per cubic metre, and electromagnetic zero-point energy, integrated to the nucleon Compton cutoff, at about ten to the power one hundred and thirteen joules per cubic metre. The roughly one-hundred-and-twenty-order gap between them is the great open problem of theoretical physics, and this thesis reads it as the measure of what is unclaimed.

The marginal cost of energy in a building. Today, fuel is most of the price of a kilowatt-hour and the whole reason a home has a bill. In that world it is zero: no fuel to buy, ship or lift. That is what "infinite efficiency" means in household terms.

The power density of the device. White's stated target is comparable to a solar cell, connected in parallel and combined in three dimensions — which is why the domestic form is a cupboard, not a power station. His programme has raised around twelve million dollars.

Reaction mass carried by anything that moves. Today, every vehicle carries and burns its energy. In that world, none — a field-drive craft carries no propellant at all, which is why the observables are hover, hard acceleration and no sonic boom.

What it would take

Finish the device. Moddel's resonator, White's cell and Chase's tunnelling diode all work inside the rule Chase states himself: you get nothing from the vacuum unless you break symmetry or drive it out of equilibrium. Each engineers that asymmetry. Chase's first cantilever deflected, then proved contaminated by deposition stress in the film, and Sandia National Laboratories is fabricating the replacements — a named systematic and a named next measurement is what a live experiment looks like. Chapter 6 and the zero-point field course take you from nothing to reading these papers. Then build the domestic form: a bench result is not a boiler, and enclosure, thermal path, vibration, service life and building codes decide whether this reaches ordinary housing in five years or twenty.

Solve the materials. Salvatore Pais and the source who goes by Anthony Williams give the same answer to why this is not already everywhere: the theory has been in the literature since Tesla and early relativity, and the bottleneck is material science. That is a fabrication problem — the most tractable kind of hard problem, and where a young engineer should aim.

Take lift seriously as a city problem. Chapter 8 teaches inertia reduction and phase-controlled field drive: the vector potential twisting the phase of a conditioned beam is what couples electromagnetism to gravity, and it is buildable at bench scale. A city needs its own version of that work — quiet, low, dense — designed by people who live in cities.

Stewardship

Retrofit first. The commercial path is premium towers. The wise path is the cold flat, the damp terrace, the village with no gas main — first, by design.

Decide about the sky while it is empty. What flies over housing, how low and how often is a choice a city gets to make once. Make it early, in public, and generously toward the people underneath.

Keep daylight non-negotiable. Free conditioning makes deep, sealed, lightless flats technically habitable. Daylight, outlook, cross-ventilation and an openable window become requirements precisely because energy is no longer the excuse.

Give the reclaimed ground to people. Land freed from parking and roadway will be claimed by something. Deciding now that most of it becomes planting, play and seating is a small policy with huge effect.

Keep the device openable. Ashton expects the rollout to be licensed and controlled. A unit only its maker may open turns the most liberating technology in history into permanent rent. Serviceability, published specifications and a right to repair belong in the first model.

Signals to watch

A vacuum cell running a room. Watch Moddel, White, Chase and Thibado. The first device to power something visible, repeatedly, before another laboratory starts the clock.

Lattice fusion carried to net power. The NASA Glenn result is published; Clean Planet in Japan with Tohoku University and Astral Systems in the UK are pushing the same phenomenon commercially. Watch for the first industrial boiler.

Engineering papers replacing physics papers. When a team stops publishing measurements and starts publishing thermal, vibration and enclosure design — and a regulator writes a code for self-powered homes — the product phase has begun.

Bench results on inertia and field-drive lift. The experiments in Chapter 8 decide when the sky above your street joins the design brief. See energy and the grid and transport for either side of the front door.
