“Ere many generations pass, our machinery will be driven by power obtainable at any point of the Universe…

“Throughout space there is energy. Is this energy static or kinetic? If static our hopes are in vain; if kinetic—and this we know it is, for certain—then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.“

–Nikola Tesla
