Modern wind turbines run pitch control at a few cycles per second, with hand-tuned response curves that struggle in turbulence and across the farm. The same blades, the same lidar units, the same servos — operated with substrate-speed decision-making, library-based control, and fleet-wide federated learning — capture meaningfully more energy from the wind that’s already passing through them. Same hardware, more useful output.
Validiti owns the substrate architecture and the coordination IP. The wind energy industry owns the blades, the servos, the lidar units, the rotors, and the towers. The match between them is published here for the field to evaluate. Architectural license terms favor genuine research collaboration and federal program partnership with NREL, DOE WETO, and the turbine OEMs’ controls research groups.
Validiti does not build pitch actuators, blades, lidar units, or any wind hardware and will not. The shape of this engagement is closer to a Bell Labs preprint than to a commercial roadmap.
Modern utility-scale turbines achieve approximately 70-80% of the Betz theoretical maximum at well-sited locations. Honest accounting of the capture loss attributable to control quality:
| Loss source | Magnitude | Why current architectures struggle |
|---|---|---|
| Suboptimal pitch tracking in turbulence | 3-7% | Hand-tuned response curves chase average wind, miss medium-eddy structure on the 100ms-1s scale |
| Wake interaction in farm | 5-15% | Downstream turbines operate in turbulent wakes the controller was not tuned for |
| Gust shedding for structural protection | 2-5% | Controllers feather conservatively because they cannot resolve gust geometry in time |
| Yaw misalignment in variable wind | 1-3% | Averaging-based yaw control misses high-frequency direction shifts |
| Aeroelastic blade behavior | 1-3% | Static blade-shape models do not track real dynamic flex during operation |
Speed alone gets a faster loop. The substrate adds four structural properties that current controllers do not.
The library can contain rare operating states from prior operation. Off-nominal regimes — high turbulence intensity, wake states, asymmetric loads, aged blade aerodynamics — are handled natively rather than as exceptions a hand-tuned controller fails on.
Three blades, root strain, tip accelerometer, blade pitch, hub forces, nacelle wind sensor, forward-looking lidar — 30+ correlated channels. Joint-pattern recognition catches multi-blade signatures that per-blade controllers structurally miss.
Forward-looking lidar gives 100-500 milliseconds of wind-field preview. Sub-millisecond decision time uses the entire lookahead window — the turbine pre-pitches before the gust arrives, configured for the specific gust geometry rather than its average.
Every turbine in a fleet experiences different conditions. Their experience composes into a federated library, signed and bidirectional. The next turbine that hits an unusual condition has prior recovery already loaded. No current wind-control architecture does this.

Validiti is not building pitch actuators, blades, lidar units, or any wind hardware. We are not pursuing wind energy as a commercial Marketplace SKU. The substrate-on-wind-pitch-control architecture is research-mode work, published for the field, available for licensing to hardware partners and research collaboration with labs and program offices.
Architectural argument, available on request to qualified wind-energy researchers, hardware partners, and federal program affiliates. Preprint paper in preparation; will appear on arXiv and through wind- energy and advanced-controls research conferences. DOE WETO concept paper in draft. Patent filings on the substrate-on-wind-control architectural mapping in process.
