Invented by Mr Guy Andrew Vaz of GVWT Energy Pte Ltd after more than a decade of development, the GV Turbine is a Guide Vane Augmented Vertical Axis Wind Turbine. Large retractable guide vanes capture and amplify wind from any direction, delivering significantly more kinetic energy to the rotor than ambient wind alone.
Green Development is the exclusive Australian representative of GVWT Energy.
Retractable sails positioned around a vertical rotor capture wind from any direction and channel it toward the blades.
The vane geometry increases both momentum and velocity before air reaches the rotor, extracting far more energy than ambient wind alone.
The vertical rotor converts this amplified airflow into electricity, operating from as low as 3 m/s and up to 30 m/s wind speed.
Approval In Principle issued by Bureau Veritas for certification as a Wind Turbine.
First patent family granted across 40+ countries. Additional patent families in progress.
Generates from 3 m/s. Viable across sites where conventional turbines cannot operate economically.
Green Development is the only point of contact in Australia for licensing and deploying the GV Turbine through GVWT Energy.
The GV Turbine represents a genuine advance in wind energy technology, not an incremental improvement, but a different approach altogether.
