Hypercars: Speeding the transition to solar hydrogen

A discontinuous transformation now underway in automotive technology may accelerate the transition to transportation powered by solar hydrogen. Even using internal-combustion engines, ultralight, ultraslippery, advanced-composite, hybrid-electric “hypercars” can be severalfold lighter and lower-drag than present steel cars; many times more efficient; and over two orders of magnitude cleaner; yet equally safe, sporty, comfortable, durable, beautiful and (probably) affordable. The required design integration is technically and culturally difficult. Yet important manufacturing advantages permit a free-market commercialization strategy impelled not by government mandates or subsidies but by manufacturers' quest for competitive advantage and customers' desire for superior cars.
