Tesla’s dream of wireless electricity made real
Several American technological companies are developing methods of wireless energy transference, as was once envisioned by legendary inventor and electrical engineer Nikola Tesla. The details the firms are using in their various methods of delivering wireless power differ from Tesla’s ideas, particularly in terms of the amount of power and the distance it travels.
WiTricity has demonstrated the ability to send enough energy across a room to run a flat-screen television using its approach, called “resonant magnetic coupling”. This is different from Tesla’s approach, but the firm’s founders have acknowledged his pioneering work.
Similarly, Computer giant Intel is working on ways of harnessing already-existing television and radio signals and converting them into power sources for small gadgets.
