-    unit: dimensionless
-    description: Betz theoretical maximum power coefficient (16/27).
-    source: Betz 1919, "Das Maximum der theoretisch möglichen Ausnützung des Windes durch Windmotoren" — the universal upper bound on Cp for any wind energy extraction device.  A candidate value for a power-coefficient constant; the empirical operating value is somewhat lower.

-    unit: kW
-    description: Senvion MM82 turbine datasheet rated power.
-    source: Senvion (now Nordex) MM82 turbine product datasheet — the rated electrical power output at v ≥ v_r.  A candidate value for the asymptote / rated-power constant.

-  - name: silicon_solar_band_gap
-    value: 1.12
-    unit: eV
-    description: Crystalline-silicon photovoltaic semiconductor band gap.
-    source: A solar-energy domain quantity but irrelevant to wind power generation, which operates via mechanical kinetic-energy extraction rather than photon absorption.
