Nanoscale powders and nanoparticles will be able to enhance the physical properties of automobile, aircraft, watercraft, trains, and spacecraft. Planes, trains, and automobiles will be lighter, faster, and more fuel-efficient and constructed of lighter, stronger materials. Some of these lightweight materials will include aluminum bodies for automobiles, brake systems for high-speed trains, and quieter aircraft engines. The stronger, lighter materials will help in energy efficiency and reducing mass and weight of finished products. See Chapter 6 for more information about automobiles and aircraft.
