Frase di Nikola Tesla

[The economic transmission of power without wires is of all-surpassing importance to man. By its means he will gain complete mastery of the air, the sea and the desert. It will enable him to dispense with the necessity of mining, pumping, transporting and burning fuel, and so do away with innumerable causes of sinful waste. [...] It will make the living glorious sun his obedient, toiling slave. It will bring peace and harmony on earth]
