Surface-wave energy transmission proven in 1893. The maths arrived in 2026. Hogeland is the first neighbourhood to deploy it.
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.
TX pod pushes energy through soil. Node harvests. Balloon adds atmospheric charge. LED lights up.
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.
Before EED you could only stumble into these effects. Now you can engineer them.
Health monitoring, wealth generation, and civic resilience — built on physics 150 years overdue.
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.
Physical sensors feed real data into each resident's Berichtenbox. Health data (damp, mould risk), wealth data (energy use, heating efficiency).
Neighbourhood-scale power beaming from a single transmitter. Residents register a receiver, receive a key, receive power. The cooperative earns 70% of relay fees.

€956 total setup. Every capability serves the neighbourhood within months. Add €460 for biophoton UPE camera.
No sphere. No battery. No wiring. One push and forget.
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.
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.
Recharges in minutes from Earth TX or ambient RF.
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.

400 battery-free nodes. Every packet is empirical evidence of wireless power delivery.
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.
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.
Soil conductivity effect on TX efficiency. Wet sandy peat soil (Hogeland) is near-optimal. The data will show exactly how much rain helps.
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.
