Nikola Tesla proposed wireless power transmission in 1899 using a radiative method that wasted much of the power. In 2007, six MIT scientists were able to transmit power to a light bulb within 2 meters at 9.9 MHz using a nonradiative mutual induction method. Witricity works through mutual induction and has applications for consumer electronics, industries, transportation, military uses, and medical devices.

IN 1899 NIKOLA TESLA
PROPOSED A METHOD OF
WIRELESS POWER
TRANSMISSION.
AS IT IS IN RADIATIVE
MODE,MOST OF THE
POWER WAS WASTED AND
HAS LESS EFFICIENCY.
IN 2007,6 MIT SCIENTISTS
TRANSMIT POWER TO A
BULB WITHIN A DISTANCE
OF 2m. AT A FREQUENCY
OF 9.9MHz. WHICH IS
NONRADIATIVE.
