Personal Levitation Systems
MINIATURIZED HALBACH ARRAYS
The rotating Halbach array generates lift through eddy-current repulsion in a conductive floor. At 3,600 RPM with a 200 mm array diameter over 6061 aluminum, the calculated lift force exceeds 1,350 N — sufficient for a 90 kg rider with margin.
THE FLOOR
6061-T6 aluminum alloy plate, 20–40 mm thick, serving as a passive eddy-current track. No power supply, no moving parts, no cryogenics on the ground side. The floor is inert metal—the intelligence is in the board.
THE BOARD
Miniaturized Halbach array of N52-grade neodymium magnets arranged in a rotating flux pattern, driven by a brushless motor at 2,400–4,800 RPM. At sufficient relative velocity, the array induces eddy currents in the conductive floor (6061 aluminum, minimum 12 mm thickness) that generate a repulsive force proportional to the square of angular velocity. At 3,600 RPM with a 200 mm array diameter, the calculated lift-to-weight ratio exceeds 1.5 for a 90 kg payload. No superconductors required at the consumer tier — room-temperature operation, but power consumption of 800–1,200 W limits battery endurance.
SCALING PATHWAY
Three tiers from entertainment to transit:
Tier 1 — Recreation: Hoverboard parks and rinks with 12 mm 6061 aluminum floor panels. Consumer-grade boards: 25 kg, 1.2 kWh lithium-iron-phosphate pack, 15–20 minute endurance at 90 kg rider mass. Maximum hover height: 15–25 mm, limited by eddy current decay rate with distance.
Tier 2 — Campus Transit: Levitating personal pods on aluminum-surfaced pathways. Frictionless, silent, zero-maintenance track. Deployed at the Institute campus and Modular Habitats installations.
Tier 3 — Urban Integration: Fermat Logistics integration for last-mile freight and passenger movement. Aluminum-embedded roadways in city-scale infrastructure.
The H-LEV system that moves a maglev pod at 500 km/h uses the same Halbach array physics that floats a consumer hoverboard 20 mm above an aluminum surface. The engineering differs in scale — coil diameter, field strength, cryogenic requirements — not in fundamental principle.
