Well, radiometers are explained by gas molecules recoiling off the
black vanes (gas expansion).

However, when photon interaction is talked about it is always the
electron that is the recipient of energy transfer. Why can't a proton
or neutron also be a recipient?

Say if I had a vacuum tube free floating in space would it exhibit a
net acceleration when an electron current flowed through it?
