Designing and making cars differently ± emphasizing ultralight weight, ultralow drag, and integrated design ± can reduce required propulsive power by about two-thirds. This can make direct-hydrogen fuel cells and commercially available compressed-hydrogen-gas tanks practical and affordable even at relatively high early prices. Coordinating such vehicles(More)
Thermoplastic advanced composites are a rapidly growing field of advanced materials. Comprising reinforcing fibers embedded in a matrix of thermoplastic resin, these materials offer high specific strength and stiffness and low density. In addition, thermoplastics' high toughness makes their use appealing in applications that require energy absorption and(More)
