Gravitas-Magnes Engines

The Gravitas-Magnes Engines are often refined and modified depending on their use.

Etymologically, the term originates from "Gravity Magnets".

The manipulation of magnetic fields, created via electrical power (steam or in some ships via lightening nets) allow airship travel.

Ships of a larger nature typically have 5-10 large black "Plates" or discs on the hull to control levitation and navigation.

The plates must be heavily shielded to prevent interferance with other ship instruments.

It is rare to see a larger vessel operating solely through the use of "G.R"s, as any catastrophic damage to the hull or plates directly, or engine failure would cause near instantaneous plummetting. Instead it is common for a zepplin style balloon and sails to still be employed for low cost and slower travel (or naval navigation). These may be deployed in an emergency situation with relative ease, as a fail safe.

Smaller boats (such as single person, often used by SkyWriters) may be entirely reliant on smaller plates, having most the hulls constructed of G.R material, and most weaponry/space given way to small generators, with low fuel capacity.

Due to the energy requirements of G.Rs most large vessels have back up power aquirement systems, such as lightening nets, which fan out from the hulls (also used for stabilisation in flight), which may syphon electricity from charged atmospheres.

Other examples include large boiler rooms of pistons, oil and coal, however carry a higher risk of fuel exhaustion or explosion if inappropriately cared for.

Recently the "Hux" Gravitas-Magnes was developed, named for it's creator, Dr.Hux - a miniature model, with short lived charge for immediate and temporary boost.
