Cordless Electricity

A room where everything has power and nothing has a cord

The room where nothing happens — instrument sight reveals what the room never shows.

What this is

The product is invisibility: a ceiling emitter array keeps every device in the room charged, and the proof is what is missing — no outlets in use, no cables sagging behind the furniture. Beams retarget electronically when things move, and a gaze guard kills any beam before eyes can arrive in its path. The room simply works, and never explains itself.

The optical micro-grid

A dense array of low-power, non-ignition lasers transmits continuous energy across an indoor space — a centralized solid-state emitter matrix paired with decentralized, intelligent device battery buffers, scaling from a studio to an enterprise floor. Each module is stripped to diode, driver, and collimating lens: a 5.5 × 15 mm cylinder. Honeycomb-packed, 3,434 of them nest into a single square foot, and at a non-burning 78 mW per beam that array puts out 267.85 W of optical power.

Receiver plates

The collector is a 4 mm-thick rigid plate of Indium-Gallium-Arsenide photovoltaic wafers — about two stacked quarters. At 60% optical-to-electrical conversion a single 1 ft² plate yields 160.7 W of continuous electricity, a steady 3.85 kWh across a day. A hard physical threshold caps any one plate at 50 concurrent beams, so no single point can be overloaded or overheated.

Buffered by design

Every device on the grid carries an internal pack holding twice the capacity its duty cycle needs. Startup surges — a refrigerator compressor kicking on — are absorbed entirely by that local buffer, so the array never sees the spike; it sees a flat maintenance demand to refill. The same deep reserve rides straight through alignment drops, thermal drift, or a momentary obstruction without a flicker.

Two-stage targeting

Coarse first, then certain. Devices beacon their battery and draw over BLE; the array reads angle-of-arrival phase shift to fix each one in 3D space and steers a beam to it. Then the optical handshake confirms the path: the array pulses a device-specific pattern (e.g. 100 kHz), a passive 0 mW retro-reflector on the plate bounces it straight back, and only when that exact reflection returns does the cluster lock on and ramp to continuous transmission.

Safe two ways

The reactive floor: if a person, pet, or object breaks the beam path, the optical handshake drops and the orchestrator kills that cluster of beams in under one millisecond — before any optical energy can register or harm. On top of it sits the predictive gaze guard: approach is detected and the beam is pre-empted before a line of sight to the eye can even form. The reactive cut-off is the guarantee; the gaze guard means it almost never has to fire.

Allocation without moving parts

A central orchestrator recomputes a “desperation metric” — time-to-empty, not raw battery percentage — and redistributes the beam pool proportionally to need, so a surging fridge outranks a device that merely reads low. Beams move electronically through liquid-crystal optical phased arrays, retargeting in microseconds with nothing mechanical to wear out; the 50-beam plate cap and a clean cut-off at 100% charge free streams for lagging devices. Total tracking overhead is ~5.02 mW per device — a 0.003% tax on the 160 W it delivers.

What it covers

Because each plate is so power-dense, the footprint stays tiny: a 500 sq ft apartment (3–5 kWh/day) needs two plates; an 8,000 sq ft building (up to 80 kWh/day) needs only 21 square feet of receiver plate across the whole property. The grid carries lights, refrigeration, routers, TVs, and laptops while leaving the utility connection in place for the high-draw thermal loads — air conditioning, ovens, water heaters — it is not trying to replace.
