Abstract
The Crookes radiometer provides a compact laboratory system for studying the conversion of radiant, thermal, and mechanical effects into rotational motion. This paper examines the radiometer as an experimental platform for Quantum Measurement Units (QMU) and the Aether Physics Model (APM), with emphasis on rotational response, pressure asymmetry, thermal gradients, and possible Aether-mediated interpretations of radiometric motion.
Within the QMU framework, radiometer behavior is analyzed through quantized mass, length, frequency, charge, and rotational units. The device is treated as a measurable system in which photon interaction, thermal boundary behavior, gas dynamics, vane geometry, and rotational output can be organized into a dimensional ledger.
The paper contributes to QADI's experimental program by identifying the Crookes radiometer as a practical apparatus for studying force conversion, torsional response, and QMU-normalized laboratory measurements.
Purpose of the Paper
The purpose of this work is to develop the Crookes radiometer as a laboratory test case for QMU. The radiometer is simple enough to reproduce, yet complex enough to involve radiation, heat, gas pressure, surface asymmetry, and rotational acceleration.
This makes it useful for examining:
- Radiation-to-rotation coupling
- Thermal-gradient force production
- Photon momentum and surface interaction
- Low-pressure gas dynamics
- Vane geometry and torsional response
- QMU-normalized torque and rotational frequency
- Experimental bridges between optical, thermal, and mechanical quantities

The Crookes radiometer is especially valuable because it connects visible radiation, thermal absorption, residual gas behavior, and mechanical rotation in a tabletop apparatus. This allows QMU quantities to be compared against directly observable motion.
A useful experimental sequence would measure light intensity, vane temperature, vacuum pressure, rotational acceleration, steady-state angular velocity, and spin-down behavior. These values can then be translated into QMU units for comparison with APM rotational and torsional quantities.
Because the radiometer responds strongly to pressure, thermal gradients, and surface properties, it is also suitable for systematic control tests involving different vane coatings, pressures, gas compositions, illumination spectra, and chamber geometries.
Recommended Laboratory Measurements
A complete QMU radiometer study should record illumination spectrum, optical power, chamber pressure, vane dimensions, vane mass, surface emissivity, temperature differential, angular acceleration, equilibrium angular velocity, and deceleration after illumination is removed.
