Nikola Tesla 
Problem of Increasing Human Energy, With Special References to the Harnessing of the Sun’s Energy [EPUB ebook] 

Nikola Tesla was a genius who revolutionized how the world looks at electricity. "For ages this idea [that each of us is only part of a whole] has been proclaimed in the consummately wise teachings of religion, probably not alone as a means of insuring peace and harmony among men, but as a deeply founded truth. The Buddhist expresses it in one way, the Christian in another, but both say the same: We are all one."
