Schaefer recounts his accidental discovery, in 1946, of a way to eliminate the supercooling of clouds which caused airplane wings to ice; a look at the Tour de France, where cyclists and designers continually experiment with ways to increase speed; a discussion of the work of German immunologist Paul Ehrlich, who, in 1901 discovered a cure for syphilis; a scientist who looks in the ocean for organisms, avoided by others, which may contain chemicals that fight disease; and another visit to the Human Powered Championship, including interviews with designers of unusual vehicles.
