The Master Key

by L. Frank Baum

A boy discovers a hidden workshop of a long-dead inventor and the electrical marvels within it, decades before most of that technology actually existed. Baum wrote adventure stories for boys the way he wrote Oz for girls, with the same generous, inventive delight. It has aged into something closer to prophecy than the author likely intended.
