Tesla on wireless electricity
For instance, in "On Electricity",
"I wish much to tell you on this occasion—I may say I actually burn for desire of telling you—what electricity really is (...) But we shall not satisfy ourselves simply with improving steam and explosive engines or inventing new batteries; we have something much better to work for, a greater task to fulfill. We have to evolve means for obtaining energy from stores which are forever inexhaustible, to perfect methods which do not imply consumption and waste of any material whatever. (...) In fact, progress in this field has given me fresh hope that I shall see the fulfillment of one of my fondest dreams; namely, the transmission of power from station to station without the employment of any connecting wire. Still, whatever method of transmission be ultimately adopted, nearness to the source of power will remain an important advantage."
Also more to draw from World System of Wireless Transmission of Energy:
"The transmission of power without wires is not a theory or a mere possibility, as it appears to most people, but a fact demonstrated by me in experiments which have extended for years. Nor did the idea present itself to me all of a sudden, but was the result of a very slow and gradual development and a logical consequence of my investigations which were earnestly undertaken in 1893 when I gave the world the first outline of my system of broadcasting wireless energy for all purposes. (...) The transmitters have to be greatly improved and the receivers simplified and in the distribution of wireless energy for all purposes the precedent established by the telegraph, telephone and power companies must be followed, for while the means are different the service is of the same character. Technical invention is akin to architecture and the experts must in time come to the same conclusions I have reached long ago. Sooner or later my power system will have to be adopted in its entirety and so far as I am concerned it is as good as done. I"
Why do I blog this? of course Tesla's exhuberant (and ultra-positivist) claims are kind of weird today (although you can find them stated by lots of people) but what I find intriguing here is how his long-chased goal is still a research purpose lately. Some great lessons about the relationship between time and innovation. If your read his stuff, you can notice how the end of the 19th century was described and seen as an accelerating moment in time, where innovations was sparkling here and there "like never before".
