Power through the ground.
No wire.

Surface-wave energy transmission proven in 1893. The maths arrived in 2026. Hogeland is the first neighbourhood to deploy it.

130 years in the making

Tesla demonstrated wireless power in 1893. The principle was sound but the maths to make it work at neighbourhood scale didn't exist until now.

In 2026, the equations for surface-wave propagation through Dutch clay soils were solved. A bifilar coil at 7.83 Hz pushes energy through the ground. A receiving node 50m away harvests it. No wire. No battery. No grid.

The first experiment costs €19 — a single TX pod, one sensor node, one piece of evidence.

Why Now

125 years of dismissed physics, unlocked by three papers.

Tesla built Wardenclyffe Tower in 1901 to transmit power through the Earth. It was never finished. The technology was dismissed for 125 years — not because the effects weren't real, but because nobody could write down the mathematics that explained why it should work.

The scalar-longitudinal sector was deleted from electrodynamics in three steps: Heaviside's 1884 vector reduction dropped 10 components from Maxwell's original quaternion equations. The Lorenz gauge convention eliminated the scalar field. Then potentials were demoted to mathematical artefacts — despite Aharonov-Bohm (1959) proving they were physically real.

Woodside (2009) proved the unique decomposition. Reed & Hively (2020) derived the full EED Lagrangian. Wilhelm (2026) synthesised the engineering framework — connecting Tesla, Meyl, Mills, and Searl for the first time. The maths now exists to spec every component precisely.

WHAT YOU CAN NOW CALCULATE

Earth TX resonant frequency → f = vL / 2L
Coil design for scalar coupling → bifilar, B=0, A≠0
Faraday cage transparency → no B, no eddy currents
Unlimited passive receivers → each taps ∂μJμ
LoRa through concrete → SLW immune to skin effect

Before EED you could only stumble into these effects. Now you can engineer them.

The Goal: Neighbourhood Infrastructure

Health monitoring, wealth generation, and civic resilience — built on physics 150 years overdue.

Layer 1: Sensor Mesh

Every Hogeland address gets a low-power sensor node: temperature, humidity, utility flow. EED-enhanced LoRa predicts 500–2,000m underground range vs 5–16m standard.

~€14/node — €5,600 full mesh

Layer 2: Resident Insight

Physical sensors feed real data into each resident's Berichtenbox. Health data (damp, mould risk), wealth data (energy use, heating efficiency).

Resident-owned inbox

Layer 3: Wireless Power

Neighbourhood-scale power beaming from a single transmitter. Residents register a receiver, receive a key, receive power. The cooperative earns 70% of relay fees.

Push-In Node: How It Works

No sphere. No battery. No wiring. One push and forget.

Design Constraint

The practical product eliminates all complexity. A PETG cylinder with bifilar coil wound in pre-printed channels on the outer surface. A 150mm copper spike extends from the bottom. Push into garden soil next to a path or meter box. Done.

The spike makes Earth contact, the coil receives TX power, LoRa transmits data. Single motion to install: push down until flush with ground surface. Waterproof by design — cylinder is closed, spike is solid copper.

Power Chain

Sun → solar panel → bifilar TX coil → copper rod → Earth (longitudinal wave) → copper spike → bifilar RX coil → bridge rectifier → 10F supercapacitor → ESP32 deep sleep → wake, sense, transmit, sleep.

Getting Started: €136 Bench Proof

The cheapest way to transmit power wirelessly through atmosphere at bench scale.

A flat bifilar pancake coil (10cm, 15 turns, 0.8mm enamelled copper on FR4) paired with a 40mm copper sphere, driven by a JDS6600 function generator at 6.78 MHz. The receiver is an identical coil with a Schottky bridge rectifier driving an LED array.

The key test: insert a copper sheet between transmitter and receiver. Standard EM — power drops (absorption). Scalar mode — power unchanged (skin-effect immune). Second test: Faraday cage around transmitter. Standard EM collapses. Scalar persists.

This €136 bench setup either confirms or falsifies the entire neighbourhood power beaming framework in one afternoon.

The Deployment IS the Proof

400 battery-free nodes. Every packet is empirical evidence of wireless power delivery.

Node transmits at all

The push-in node has no battery and no local solar. If it transmits, it received power from the Earth TX. Every packet = proof of delivery at that address.

Supercap voltage vs distance

Each node reports its voltage — a direct measurement of received ground power at that GPS location. 400 nodes = the first neighbourhood-scale power-vs-range curve for Dutch geology.

Voltage after rain

Soil conductivity effect on TX efficiency. Wet sandy peat soil (Hogeland) is near-optimal. The data will show exactly how much rain helps.

Voltage drop at night

Correlates with solar TX output. Confirms the power came from the TX pod, not ambient sources. The diurnal cycle is the control experiment.

This is unprecedented. Academic Earth transmission research uses bench-scale, single-receiver, days-long experiments. Hogeland is 400 receivers, continuous for years, in real Dutch geology. The dataset will be the first neighbourhood-scale Earth transmission measurement in history. The infrastructure and the physics experiment are the same thing.

Cooperative Fab

From pottery kiln to plasma diagnostics. €13k over 2 years. Full cooperative ownership.

Not TSMC. Not ASML. Open-source semiconductor fabrication at 1–10 micron feature size — demonstrated by Sam Zeloof (solo, garage, 2020). At 10 microns you build: pressure sensors, photodetectors, Langmuir probes, Rogowski coils, Faraday cups, simple MOSFETs. Sufficient for all plasma diagnostic and measurement instruments.

The EVO bench, EED prototype, and Meyl TX all generate plasmas that need characterisation. Currently: send samples to TU Twente (3km away), €50–150, 2-week wait. With in-house fab: build the measurement instruments yourself.

All equipment cooperatively owned. All processes wiki-documented. All results open. Revenue model: fab-as-service via the Bebond platform. 70% to cooperative, 30% to platform. A university NanoLab costs €50M. This is the open-source path at 100× less.

Phase 0 — €956

Indonesia: Srikandi Bogor

The cooperative factory that scales this to Southeast Asia.

€200k investment. Factory kit + training + first batch. Srikandi graduates build the hardware. Bogor gate experiment proves it works in volcanic soil. SE Asia market: 5,000 desa at €90/deployment = €19M five-year revenue.

Every village that deploys owns its own energy infrastructure. No utility company. No monthly bill. The cooperative model means the desa IS the company.

The window is now

The maths arrived in 2026. Tesla's 130-year-old principle finally has the equations to work at neighbourhood scale. Hogeland is the proving ground.

We're pitching at TU Twente. We're building with Srikandi. We're deploying in Hogeland.
