The Problem of Increasing Human Energy With Special Reference to the Harnessing of the Sun's Energy

Part philosophical ponderings on humanity's relationship to the universe, part scientific extrapolation on what technological advancement might bring to that understanding, this long essay, first published in Century Illustrated Magazine in June 1900, is yet another example of the genius of Serbian inventor NIKOLA TESLA (1857-1943), the revolutionary scientist who forever changed the scientific fields of electricity and magnetism. From the possibilities presented by robotics to the "civilizing potency of aluminum," from a "self-acting engine" to one of the first proposals to use solar power to run industrial civilization, and much more, this is a wide-ranging but illuminating look into the thoughts of an unsung hero of scientific philosophy.
"Of all the endless variety of phenomena which nature presents to our senses, there is none that fills our minds with greater wonder than that inconceivably complex movement which, in its entirety, we designate as human life; Its mysterious origin is veiled in the forever impenetrable mist of the past, its character is rendered incomprehensible by its infinite intricacy, and its destination is hidden in the unfathomable depths of the future. Whence does it come? What is it? Whither does it tend? are the great questions which the sages of all times have endeavored to answer."
