SOLAR RADIATION PROPELLED VEHICLE
For journeys close to the Sun it might be possible touse a large mirror which collected the Sun's rays andconcentrated the energy on a working fluid. Althoughthe thrust created would be small, it would be suffi-cient, over a long period, to impart a very highvelocity.
The mirror would have to be rotatable through anangle of 360so that it always faces the Sun. Ideasfor using the Sun's radiation directly as a means ofpropulsion have also been proposed, but they areimpracticable at present.
