SOLAR RADIATION PROPELLED VEHICLE
For journeys close to the Sun it might be possible to
use a large mirror which collected the Sun's rays and
concentrated the energy on a working fluid. Although
the thrust created would be small, it would be suffi-
cient, over a long period, to impart a very high
velocity.
The mirror would have to be rotatable through an
angle of 360so that it always faces the Sun. Ideas
for using the Sun's radiation directly as a means of
propulsion have also been proposed, but they are
impracticable at present.
