It is shown that energy relaxation of infrared radiation heated electron gas results in equal and oppositely directed currents in spin-up and spin-down subbands caused by spin dependent electron-phonon interaction. In experiment on SiGe structures a pure spin current was converted into electric current by application of a magnetic field distorting the balance between the two partial currents.
