Even solar sails use that effect (momentum of sunlight).
No that is a heat engine. Temperature differences on either side cause
the motion. Radiant heat is em waves raising the temperature on one side,
that facing the sun.

You are confusing the action of the Crookes' radiometer with Nichols'
radiometer.
https://en.wikipedia.org/wiki/Crookes_radiometer
Crookes' radiometer is a heat engine that uses a light source as the
source of (radiant) heat, and a working substance, air.
https://en.wikipedia.org/wiki/Nichols_radiometer
Nichols' radiometer measures radiation pressure caused by light
momentum. The concept of photons are not required to explain this
momentum, Maxwell's wave theory is sufficient.
https://en.wikipedia.org/wiki/Radiation_pressureThanks for the links. Yes wave theory is sufficient to explain so-called radiation pressure. As I explained the temperature difference caused by currents causing heat on the lighted side causes the motion. This does not mean that light has momentum. It is an aetheric disturbance causing fluctuations in the orbital paths of electrons thus causing potentials to drive the heat creating currents. The heated atoms push against the cooler atoms till that force reaches the last layer of atoms. Having nothing to push against they have to move. Thus there is motion from the impact of light.
