Tesla's research into
wireless transmission of energy would continue in Colorado
Springs (1899-1900) and Wardenclyffe Tower (1900-1917), where
large Tesla transformers were created to understand the nature
of electricity. He envisioned that the Wardenclyffe Tower
would be designed as an demonstration to create global free
wireless electricity. The video link at the bottom is a
dramatization of what was Tesla hoped the mastering of
electricity could offer the world.
