The technology
The patented Generator Array.
A modular system of smaller drives on a common support shaft, which can be driven by any form of renewable kinetic energy and switched to stored energy for continued rotation of the generator array and continuous energy supply.
01
How It Works
One large generator replaced by a smart array.
A conventional generator is a single machine operating at a fixed RPM. When the input drops below the threshold, it stops entirely. The Generator Array links several individual drives via a series of rigid ties on a common support shaft. All rotors spin in unison, but each stator is controlled independently to match the torque available in real time.
The array can be driven by any locally available renewable kinetic energy source: wind, tidal, wave, water or thermal. When that source drops away, an electromagnetic coupler disconnects the array from the capture mechanism and it is driven instead by localised stored energy, so rotation of the generator array and the energy supply both continue uninterrupted.
The array can be mounted horizontally in a nacelle or vertically in a tower, and a gearbox is optional depending on configuration.
01
Capacity optimisation
Stators activate in sequence to match available torque. Weak input still generates. Strong input generates at full capacity.
02
Built-in redundancy
If one drive fails, the rest continue. Maintenance on a single unit never means downtime for the whole array.
03
Scalable by design
Add drives to increase capacity. Each unit is lighter and easier to manufacture, transport, erect, install and commission than a single large generator.
04
Any kinetic input, plus stored fallback
Any renewable kinetic energy source drives the array. When it drops to zero, the coupler disconnects and the array runs on compressed or liquid air, flywheel, gravity or hydro.
02
Conventional vs. the array
The conventional way
One large generator
A single heavy machine generating at a fixed RPM. Efficient only within a narrow band of operating conditions.
Stops when the resource drops. No operation below 3 m/s or above 25 m/s
Single point of failure
Fixed capacity, heavy, high capex
Requires fossil backup
The Green Flow way
The Generator Array
Many smaller drives on one support shaft. Stators activate to match available torque, continuously and in real time.
Starts generating from 1 m/s, keeps turning on stored energy when the wind stops
Modular redundancy built in
Scalable Kw to Mw, up to 25% lower capex
Zero emissions, no fossil fallback needed

Applications
One platform, deployed across very different worlds.
The same core architecture adapts from grid-scale power stations to the inside of a vehicle. Each setting solves a different commercial problem, and each is a separate route to market.
Renewables: wind, tidal & wave optimisation
The array retrofits into wind, tidal and wave assets to capture more from the rotor and structure already installed. Stators switch in to match whatever torque the resource is producing, and when the resource fails the array is switched to stored energy and keeps rotating.
High-capacity installations become viable in less than ideal geographic locations.
Benefit
Up to 2.5x the capacity from the same torque, blade diameter, footprint and structure. Lower capital cost, easier transport and installation, and generation that continues through calm periods instead of stopping.
Transport: Air-KERS onboard generation
A ducted system on the vehicle captures airflow created by its own motion and channels it through the array, generating electricity that feeds the battery or propulsion system. The method extends range while the vehicle is moving.
An independent feasibility study by Glasgow Caledonian University, supported by Interface and the Scottish Government, modelled the system on an electric bus.
Across three driving cycles it found a range extension of between 2% & 70% of a full-charge journey can be recaptured, depending on vehicle speed, at an electrical efficiency of 70 to 90 percent, with the unique ducting positioned in the vehicle and no impact on drag.
Benefit
Energy recovered on the move that is otherwise wasted, on top of regenerative braking, reducing energy consumption, demand and availability of charging infrastructure and the grid.
Grid & off-grid generation
Controllable generation from kW to MW, with built-in redundancy and the ability to be switched to stored energy when the renewable resource drops. Deployable anywhere: National grid, remote off-grid, or island micro-grid.
Benefit
Clean power with generator and grid inertia maintained through calm periods, replacing the fossil fueled gensets that currently provide back-up in off-grid and island settings.
Maritime, rail & aviation
The architecture scales into the hardest transport modes to decarbonise, from onboard vessel generation and rail installations through to aviation and multi-megawatt deployments.
Benefit
One scalable architecture across every hard-to-abate transport sector, so a single engineering pathway serves multiple markets.
