Vernier

A type of engine invented in the late Fourth Age by Dr. Edwina Vernier, the Vernier Engine is the most efficient action-reaction turbine design in the Multi-Verse. The engine is most famous for the special Vernier Fuel (also invented by the talented Edwina) which has an extremely low boiling point. The liquid fuel is heated by a coil in the pre-injection chamber, so that it enters the turbine in gaseous form for maximum combustibility. While other turbines systems have been developed that provide greater thrust, the Vernier Engine is still the king where over-all efficiency is paramount. It is especially favored in the mech field, where maximum thrust for minimum wait and lowest fuel consumption are everything a pilot needs. The Vernier Engine also holds a record as one of the very few designs that can function both in space and in atmosphere, though requires some additional equipment for space use.
