Crooks radiometer is not an example of radiation pressure. Anyone who has actually seen one can tell you the sails are pushed away from the black side, not the silvered side despite it having twice the radiation pressure. Pic related.

The actual reason it works is because of residual gases, vacuums are not total voids.

Radiation pressure is a proven fact but this is an example of why you should be careful voyaging into a topic you are ignorant about. Also a good example that experiments are not immune to systematic effects. EMdrive isn't a photon rocket, it isn't expelling photons for momentum. That wouldn't generate the claimed trust and it is now how the inventor claimed it worked (despite teh fact he is wrong).

Photon momentum mill

Why not build a space station like a giant radiometer? Sun shines on the black panels causing it to spin spin spin. Eventually it'll spin so much centripetal force takes hold and BOOM! Instant artificial gravity.
