Micro-Wind Systems · DAWT architecture
Wind energy, protected by design.
Coevo's Micro-Wind system is being developed as a compact, enclosed wind charging platform for battery-backed remote infrastructure. The system uses a DAWT-style architecture, or Diffuser-Augmented Wind Turbine, intended to improve wind capture in a compact form factor while supporting safer, more practical deployment around remote industrial assets.
Purpose
Power that shows up when nothing else can.
Solar owns the daytime. This platform owns everything else — nights, storms, winter, dust, and shade. Paired with solar and storage, it keeps field batteries at a healthier state of charge around the clock, which is where battery life, uptime, and operating cost are actually won.

Diffuser-Augmented Wind Turbine
What DAWT means, in plain terms.
DAWT stands for Diffuser-Augmented Wind Turbine. Coevo's Micro-Wind system uses a DAWT-style architecture intended to improve wind capture in a compact, enclosed form factor for remote infrastructure and battery-backed field assets.
Coevo's Micro-Wind architecture is designed to use a compact diffuser and enclosure approach to support wind capture in remote, industrial, and infrastructure-based environments. The rotor is an enclosed-blade vertical-axis design, and the surrounding shroud has been engineered with an integrated diffuser intended to improve blade protection and low-wind performance. Aerodynamic gains are design intent and remain subject to wind-tunnel validation.
What the architecture is intended to do
- Improve wind capture in a compact form factor
- Protect the blades behind a structural enclosure
- Support low-wind performance at typical field sites
- Accept wind from any horizontal direction, without yaw
- Enable deployment where open blades are restricted
Aerodynamic performance gains from the diffuser are design intent and remain subject to wind-tunnel validation.

The conceptual comparison shows how supplemental wind input may reduce depth of discharge versus battery-only and solar-plus-battery systems — lifting the overnight floor that drives battery wear.

Where the air actually goes.
CFD analysis lets the program evaluate rotor geometry, diffuser and shroud interaction, and wake behavior in simulation — resolving design questions long before a prototype is cut. These are results from a development rotor at a low-wind operating point.

Velocity field — elevation section
A vertical slice through the complete assembly. Air enters through the louvered shroud, works on the rotor, and exits downstream — while the housings above and below sit in near-still air.
How to read it
Shows how the protective enclosure shapes flow into and out of the rotor.
Preliminary CFD analysis of a development rotor configuration at a single operating point. Simulation results inform design direction — they are not a substitute for instrumented power-curve testing, and no performance rating is derived from them here.
Engineering development
Built with teams that do this for a living.
Coevo develops the platform with two specialist engineering partners, each engaged where their strengths matter most — one carrying the design from simulation through fabrication, the other putting the results in a wind tunnel.
Design & build
A multi-disciplinary engineering development group
Carries a design from simulation through fabrication under one roof — the reason the program can ask a hard question and have hardware answering it the same month. The velocity fields and streamlines above are output from their work.
- Aerodynamic analysis and CFD simulation
- Mechanical design with structural and load-path analysis
- Rapid prototyping, machining, and in-house fabrication
- Design for manufacturing and production readiness
- Generator, power-conversion, and controls integration
Test & validate
An aerodynamics specialist with wind-tunnel facilities
Deep heritage in wind and flight systems, engaged to build test articles and characterize what the hardware actually does under controlled, repeatable conditions — the step that turns a simulated result into a measured one.
- Wind-tunnel testing across controlled wind speeds
- Applied aerodynamic design and analysis
- Prototype and test-article fabrication
- Performance characterization and data capture
- Independent validation of simulated results
Why we split the work
Enclosed micro-wind is a harder problem than an open rotor: the shroud, rotor, bearings, generator, and containment all interact, and every change to one moves the others. Simulation narrows that design space quickly and cheaply — but a wind tunnel is what tells you which parts of the model were right. Keeping the two in separate hands means our aerodynamic results get checked by a team that didn't produce the model.
Safety begins with controlling the moving system.
Surrounding the rotor with a protective structure is what lets Coevo pursue sites where exposed rotating machinery is unsuitable or restricted. These are engineering intents — each one subject to validation of the complete assembly.
- Reduced direct access to rotating blades
- Potential containment of damaged rotor components
- Reduced wildlife contact exposure
- Reduced risk from exposed rotating machinery
- Potential reduction of conventional blade-throw concerns
- Better fit for compact sites
- Greater control over ingress
- Application-specific screening options
- Cold-weather mitigation opportunities
- Protection of internal components
What enclosure does not automatically establish
Equipment qualification is based on identifying and mitigating risk pathways — including ignition pathways in classified locations — across the complete assembly. Enclosure is a prerequisite, not a certification conclusion.
Enclosure alone does not establish ATEX certification.
Enclosure alone does not establish IECEx certification.
Enclosure alone does not establish NEC suitability.
Enclosure alone does not certify a machine as OSHA compliant.
Enclosure alone does not guarantee wildlife approval.
Enclosure alone does not prove ice containment.
Enclosure alone does not prove blade-fragment containment.
The complete assembly requires assessment.
Site suitability remains jurisdiction- and application-dependent.
Physical access and guarding
Opening size and rotor standoff must be engineered together — there is no single universal “safe opening” dimension. Small openings may prevent finger or hand access; larger slots require greater standoff; very large openings may be treated as full-body access. Mounting height changes the applicable guarding considerations, and OSHA guarding duties and ISO reach-distance standards must be considered together, particularly for rotating systems mounted at or below seven feet.
Wildlife
Wildlife risk varies by site and species, and no single opening size establishes universal compliance. Screening may reduce access, but site assessment remains necessary. Some bats may pass through openings around 3/8 inch, and for birds the governing dimension is body cross-section rather than wingspan. Enclosure may materially reduce direct rotor exposure — it does not guarantee wildlife approval.
Ice and cold weather
Enclosure may reduce external blade-icing exposure, but inlets and outlets remain open for airflow and internal ice can still accumulate. Detection, shutdown behavior, anti-icing measures, drainage, and containment may all be needed depending on climate. Cold-weather design remains under engineering review.
