Aerodynamics and Other Efficiencies in Transporting Goods

Abstract

Recognizing both the pollution effects of fuel use and the likely increases of fuel cost in coming decades puts high priority on alternative energy for trucks, buses and trains. There are still gains available in decreasing aerodynamic drag and rolling friction, using efficient engines, and minimizing fuel waste, but it is appropriate to explore decisions that would be suitable if fossil fuel were deemed unattractive. One then would consider utilizing natural energy (sunlight, wind, wave), getting energy from braking, employing hydrogen, putting different priorities on trucks vs. buses vs. trains, exploring integration with water deliveries and automatic local air transport, etc. Such an investigation might illuminate early alternatives that would at least permit partial improvements.
