One of the most promising applications for ceramics is in gas turbine engines. They can handle much higher temperatures than the metals currently used and are far less expensive. Back in the 70s and 80s, ceramics were hailed as the killer app for automotive turbine engines.
The Victorians developed effective turbines for turning water and steam power into work, and also turbopumps for doing the opposite.
During the early part of the 20th century, research was carried out into various arrangements for turbo-compression, combustion and turbine work extraction in the...
