Micro-Wind Systems · DAWT architecture
Remote power, built around wind.
Continuous generation for infrastructure operating beyond the grid.
The Coevo DAWT architecture captures distributed wind energy in a compact, enclosed turbine designed around remote infrastructure applications. It generates through the night, through the season, and through the weather that suppresses solar — behind a structural enclosure rather than on an exposed surface.

Primary configuration
Built around the DAWT 300W.
Coevo's primary remote-power configuration combines a 300W nameplate DAWT with continuous, low-wind energy generation designed around the power requirements of remote infrastructure.
At a 5 m/s average wind condition, the current modeled system generates approximately 498 Wh over 24 hours, providing continuous energy input to the site's power system. At 10 m/s (22 mph) wind speed, modeled output reaches approximately 87 W. The 300W rating is the nameplate at the rated operating condition — not a continuous output.

Modeled performance
Power at a moment. Energy over a day.
Output rises steeply with wind speed and reaches nameplate at 15 m/s (34 mph). The daily energy figures describe something different — what the unit accumulates over 24 hours at an average wind condition. Both are modeled, and both matter when sizing a system.
Modeled performance
Modeled performanceAverage output across 24 hours, against the site's average wind speed. Hover the chart to read any site.
A site that averages 5 m/s does not blow at 5 m/s — it varies. Because power follows the cube of wind speed, the windier hours contribute far more than the calm ones take away, so the day average sits well above what an unvarying breeze at the same speed would produce.

Nameplate, at the 15 m/s (34 mph) rated condition.
Watts (W) are power at a moment. Watt-hours per day (Wh/day) are energy accumulated over 24 hours. A DAWT 300W is a 300 W nameplate machine that is modeled to generate 498 Wh over a day at a 5 m/s average wind — the two numbers describe different things.
Modeled performance, not measured results. Output is derived from the aerodynamic performance measured in CFD report TR-26-0019 (September 2026), applied at sea-level air density with an assumed 80% generator and charging efficiency. Power follows the cube of wind speed, so doubling the wind is roughly eight times the power, and output reaches nameplate near 15 m/s (34 mph). Daily and average figures are evaluated across a Rayleigh wind speed distribution at a 5 m/s (11 mph) annual mean — below the lowest standard small-wind class in IEC 61400-2, which sets Class IV at 6 m/s — on the distribution basis IEC 61400-2 and AWEA 9.1 specify. These are modelled design-basis figures pending wind-tunnel validation; they are not field-validated, certified, or measured production numbers.

Protected energy capture
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 — and it is why generation happens behind a structure rather than on an exposed surface. These are engineering intents, each 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
The enclosure is not only a safety feature — it is what makes the machine work
With the diffuser vanes removed, calculated power collapsed to zero at every rotor speed tested: vortices shed from the housings shifted the apparent wind direction and reversed the torque. The result held when the analysis was repeated in a larger computational domain at a higher wind speed. The diffuser recovers that energy and delivers a far steadier torque signature, which simplifies generator matching and power electronics.
Computational analysis only. Not yet validated in hardware.
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.
Design principles
What the platform optimizes for.
Battery-first value
The platform is designed around battery-backed field assets, not around a headline generation number. The objective is a healthier state of charge across the day, not peak output in a gust.
Protected energy capture
Generation happens inside a structural enclosure rather than on an exposed surface. The rotor is shielded from weather, debris, and site hazards — a durability argument solar panels cannot make.
Solar replacement or complement
Designed to run as a standalone charging source or alongside existing solar and battery systems, adding generation for the hours and seasons when solar output is reduced.
Modular serviceability
Being developed so that bearings, rotor, generator, and shroud components can be serviced or replaced individually in the field rather than replacing a complete system.
Harsh-environment design
Configurable environmental packages target dust, salt spray, cold weather, storm loading, and high-altitude operation. Protection levels are engineering targets, not certified ratings.
Omnidirectional by design
A vertical-axis rotor inside a diffuser accepts wind from any horizontal direction, so there is no yaw system to align, drive, or maintain.
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.
How it works
From moving air to monitored power.
Six stages carry wind energy from the shroud to the battery — and report on themselves once they get there.

How to read it
Shows how the protective enclosure shapes flow into and out of the rotor.
Computational analysis of a development rotor configuration. The aerodynamic performance measured in TR-26-0019 is the basis for the modelled output figures shown elsewhere on this site. Simulation is not a substitute for instrumented power-curve testing; wind-tunnel validation follows.
Engineering development
Built with a team that does this for a living.
Coevo develops the platform with Bravo Team, a multi-disciplinary engineering group engaged through commercialization — carrying the design from simulation through fabrication.
The aerodynamic work has been continuous rather than episodic: a programme of computational fluid dynamics studies run over months, each testing a set of design changes, measuring what they produced, and feeding the result into the next round of redesign. The models are substantial — roughly 32 million cells each, run on the supercomputing cluster at the Ohio Supercomputer Center. The velocity fields and streamlines above are output from that work.
Design, build & develop
Bravo Team
Deep heritage in wind and flight systems, carrying a design from simulation through fabrication. Wind-tunnel validation of the current configuration is carried out with an independent test partner — the step that turns a simulated result into a measured one.
- Aerodynamic analysis and CFD simulation
- Mechanical design with structural and load-path analysis
- Rapid prototyping, machining, and in-house fabrication
- Performance characterization and data capture
- Generator, power-conversion, and controls integration
- Design for manufacturing and production readiness
- Prototype and test-article fabrication
Aerodynamic findings to date are from computational analysis only. Nothing here has been tested, measured, or validated in hardware. Wind-tunnel validation of the current configuration follows in October 2026, and the programme continues in parallel — the next series optimizes diffuser geometry, blade profile, rotor aspect ratio, and housing proportions.
Validation
How we do it, in order.
Coevo is advancing its Micro-Wind system through engineering validation, prototype refinement, wind-tunnel testing, battery-integration analysis, durability testing, and pilot-oriented commercialization planning.
01
Engineering validation
Aerodynamic analysis and CFD across rotor geometry and shroud configurations, used to narrow the design space before hardware is committed.
02
Prototype refinement
Blade geometry and the diffuser shroud refined from analysis findings, then translated into buildable test hardware.
03
Wind-tunnel testing
Instrumented measurement of electrical output across controlled wind speeds, replacing modeled estimates with measured ones.
04
Battery integration analysis
Charge-controller and battery-system integration work to characterize behavior against real field load profiles.
05
Durability testing
Extended-duration mechanical and environmental exposure testing across the intended operating envelope.
06
Pilot-driven validation
Field-test units with partner sites, then customer-specific use-case validation against their own equipment and service intervals.
The system has completed a computational design phase and is moving into physical prototyping and wind-tunnel testing. No performance figure on this site is a tested result unless explicitly labeled as tested, and no certification has been completed.
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.
