The company was started at a time when there was a great deal of hype surrounding ceramics, when designers were dreaming of the adiabatic engine running at a very high temperature that would cause the oil to break down," says Klatt.
This is because a truly adiabatic engine with zero heat loss is not possible (due to thermodynamic constraints), but a 50 percent to 60 percent reduction in heat loss can be achieved.
This also suggests the direction of further development of an optimally adiabatic engine (compared to previous all-ceramic combustion systems) having the potential for additional thermal efficiency improvement.

Knight's boat featured new adiabatic engines, which nearly doubled all output levels, and, at the start of the race, proved his claims of how fast it would go.
