Original editorial analysis. Fuel-saving innovations need proof under real operating conditions.
The context
BBC World Service Tech Life has raised the question of whether rotating sails could help reduce container-ship exhaust pollution.
Our analysis
Any shipping innovation must perform within a complicated commercial system: vessel schedules, port constraints, maintenance and variable weather. Fuel savings in a simulation may differ from results on actual voyages.
What to watch
Credible evidence will compare fuel use, maintenance, payload effects and operating constraints across defined routes.
