SPIRAVEX Atmospheric Energy Harvester

Revolutionary Wind Technology for the 21st Century

The first fundamental breakthrough in wind energy conversion since Tesla's bladeless turbine of 1913. SPIRAVEX operates through viscous drag and omnidirectional funnelling, enabling continuous power generation across the full range of atmospheric wind conditions.

SPIRAVEX Atmospheric Energy Harvester

How SPIRAVEX Works - Technical Deep Dive

01

360° Omnidirectional Capture

Mechanism: Toroidal convergent inlet funnel captures airflow from any horizontal direction

Velocity Amplification: 2-4x concentration through pressure differential conversion

Advantage: No yaw mechanism required - operates equally well in winds from any compass direction

Applications: Essential for platforms that cannot actively orient to wind direction

02

Viscous Drag & Vortex Generation

Mechanism: Co-axial Archimedean screw discs in alternating LH/RH configuration

Energy Transfer: Viscous boundary layer coupling transfers kinetic energy to rotational momentum

Innovation: Opposing thread geometry generates constructive vortex interference

Validation: INIJEVID experimental data confirms 2.5x torque increase vs propeller baseline

03

Bore-Flow & Vortex Cascade

Mechanism: Central bore channels airflow through disc stack axis

Self-Priming: Creates low-pressure zone drawing ambient flow inward

Cascade Effect: Ranque-Hilsch vortex amplification between disc gaps

Efficiency: Reduces cut-in wind speed and maintains entrainment continuity
