Air density: 1.225 kg/m³. For this vertical-axis rotor, area = swept diameter × blade height, using the maximum blade radius from the 3D mesh. The same assumed Cₚ applies to all creatures; no shape-specific aerodynamic ranking is implied.

Within the assumed operating range: electrical W = min(rated W, max(0, ½ρA × Cₚ × efficiency × (wind³ − start³) − fixed loss)). The start-speed subtraction is an illustrative ramp. Below start or at shutdown, output is zero. Energy Wh = W × hours at constant wind. RPM is an illustration derived from the chosen tip-speed ratio; it is not a speed prediction.

The model assumes a suitably matched low-speed generator and controller. Cogging, voltage versus RPM, gearing, torque matching, temperature, turbulence, fatigue and storage are not simulated. A larger rating does not guarantee more output. Light is supplied before sound; a negative balance indicates power that would have to come from storage or another supply.

Method background: DOE Small Wind Guidebook and NREL study of rotor and generator power. All creature coefficients, thresholds, efficiencies and dimensions here are user-editable scenario assumptions, not specifications from those sources.
