Compression Ignition: Otto, Diesel and Thermal Efficiency
Three milestones in which an engine was designed from a thermodynamic argument rather than developed from an existing machine, and immediately outperformed everything else.

Three milestones in which an engine was designed from a thermodynamic argument rather than developed from an existing machine, and immediately outperformed everything else.
Three milestones in which electricity moved into railway traction, and in which the alternating-versus-direct argument was fought again under different constraints.
Three milestones within two years, none of which invented a device. Each fixed an interface or made a hidden structure explicit, and each generated more value than most inventio…
Two milestones whose importance lies in decades of accumulated process improvement rather than in a breakthrough, and in what a zero marginal fuel cost does to a power system.
Four milestones in metallurgy and machine tools without which the steam engine would have remained a curiosity, one of them driven by an environmental crisis.
Four milestones in which marine propulsion moved from consuming most of the ship to leaving room for the cargo that paid for it.
Four milestones in moving goods overland, and a reminder that for bulk freight before the railway, water beat road every time.
Four milestones showing a field that acquired chemistry rather than physics, and in which the decisive advance came from a part-time experimenter working in a cellar.
