There are three types of propulsion modes available
to the lightcraft. These are ion-propulsion mode,
Magnetohydro Dynamic (MHD) propulsion mode, and
Pulsed Detonation Engine mode (PDE). Using these
modes the lightcraft is able to take-off vertically
and quickly accelerate itself into space. The ion
propulsion system on board the lightcraft is for
low-speed transport only. It is used mostly in the
landing and take-off. The speeds which the
ion-propulsion system can attain are equivelant to a
modern-day train. The ion propulsion system is run by
an array of solar cells which cover one side of the
lightcraft.
PDE engines are for subsonic flight like the ion
mode, but are able to propel the lightcraft much
faster.. The PDE mode is nessecary to move the the
lightcraft into MHD mode. PDE engines are capable of
performing "hyperjump" manuever in which
the lightcraft is accelerated at a speed greater than
the unaided human eye can follow. This makes the
lightcraft effectively seem to disappear. This mode
along with MHD is powered by beamed-energy from an
orbiting satelite.

The MHD engines are capable of accelerating
the lightcraft orbital speeds within the atmosphere
and are necessary for orbital flights. The MHD engine
system includes a special 'expendable coolant' system
that efficiently transfers waste heat from the
rectennas to on-board de-ionized water, which is
subsequently vaporized and ejected as steam.
