The three bladed rotor attached to the main shaft is attached to a flywheel driving the friction wheels which operate multiple generators.  The rotor and flywheel operate with the same inertia. The design is reliable because it inherently limits the torque transmitted through the drive and incorporates the following key advantages:

- No gearbox – no oil, gearbox bearings or gears to fail
- No single point of failure
- Reduced costs overall for manufacture, operations and maintenance
- Not reliant on conventional turbine supply chain for bearings, gears, generators or gearboxes
- Friction drive system built to absorb sudden wind gusts – energy is stored as momentum and recovered when gust passes
- It is impossible to overload drive train
- Multiple Generator Drive, each operate at the most efficient point – each generator only operates when there is sufficient wind, ...therefore energy yield is higher even when running below rated power
- Independent load paths giving continuous operation at part load while waiting for maintenance or replacement of component parts
- Distributed load paths allow operation up to 95% availability during faults as only the fault load path is isolated
- Distributed power system , low torques
- Ability to maintain, service and replace all drive system component parts using only the internal nacelle crane
- Full power conversion – grid friendly and variable speed
- Scalable to 7.5 MW
