About This Book
Two inventive brothers design a compact storage cell and a pocket radio, assembling and testing their devices in a home laboratory and during outings in rural Maine. Their experiments demonstrate practical uses, including powering an electric motorcycle and enabling long-distance signaling, and an expedition into the woods turns dangerous when one brother is seized. The wireless apparatus proves pivotal in summoning aid, and the narrative highlights ingenuity, cooperative problem solving, and the application of early electrical technology within an outdoor adventure.
