His own biography (somewhat stilted writing, the constant "I" self-referrals, but, dense and very interesting): My Inventions: The Autobiography of Nikola Tesla http://www.amazon.com/My-Inventions-Autobiography-Nikola-Tesla/dp/0910077002/ref=sr_1_1?s=books&ie=UTF8&qid=1328411812&sr=1-1 http://www.amazon.com/My-Inventions-Autobiography-Nikola-Tes... He had his own vision of a "singularity" basically interconnectedness of all human kind across earth to "rid ourselves" of war.
