Guide4 Aug 2026Compression Ignition: Otto, Diesel and Thermal EfficiencyThree milestones in which an engine was designed from a thermodynamic argument rather than developed from an existing machine, and immediately outperformed everything else.4 min readRead MoreGuide4 Aug 2026Electric Traction: Railway Electrification and a Second Current WarThree milestones in which electricity moved into railway traction, and in which the alternating-versus-direct argument was fought again under different constraints.5 min readRead MoreGuide4 Aug 2026Engineering the System: Containerisation, Motorway Networks and Critical Path SchedulingThree 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 inventions in this series.8 min readRead MoreGuide4 Aug 2026Generation Without Fuel: Photovoltaics and the Modern Wind TurbineTwo 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.6 min readRead MoreGuide4 Aug 2026Iron at Scale: Coke Smelting, Puddling and the Boring MillFour milestones in metallurgy and machine tools without which the steam engine would have remained a curiosity, one of them driven by an environmental crisis.8 min readRead MoreGuide4 Aug 2026Power to the Water: Screw Propulsion, Expansion Engines and Oil FiringFour milestones in which marine propulsion moved from consuming most of the ship to leaving room for the cargo that paid for it.5 min readRead MoreGuide4 Aug 2026Roads and Canals: Brindley, Tresaguet, Telford and the ErieFour milestones in moving goods overland, and a reminder that for bulk freight before the railway, water beat road every time.6 min readRead MoreGuide4 Aug 2026Steel Beyond Bessemer: Regenerative Heat, the Basic Process and Alloy SteelsFour 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.7 min readRead More
