No that is a heat engine. Temperature differences on either side cause

@bertietaylor a.k.a @ArindamBanerjee,

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.
