Utah State University presented a first-of-its-kind electric bus that is charged through wireless charging technology in a demonstration Nov. 15, 2012.
The Aggie Bus rolled onto the streets carrying passengers today; just 16 months after USU demonstrated the first high-power, high-efficiency wireless power transfer system capable of transferring enough energy to quickly charge an electric vehicle. In July 2011, the USU Research Foundation demonstrated 90 percent electrical transfer efficiency of five kilowatts over an air gap of 10 inches. The demonstration validated that electric vehicles can efficiently be charged with wireless technology.

USU’s Aggie Bus has achieved several significant milestones. It is the first bus developed and designed by a North American organization that is charged with wireless power transfer technology and is the world’s first electric bus with WPT technology combining the three following performance metrics: A power level up to 25 kilowatts, greater than 90 percent efficiency from the power grid to the battery and a maximum misalignment of up to six inches.
Phi Beta Iota: “Low” technologies capable of providing free power and clean water to the masses have been repressed for decades. They are finally creeping out of their corporate patent prisons. Free localized energy and wireless energy recharging of free cell phones (OpenBTS) are the first priority. Everything else follows from those two.
