tesla techonology still has it

Nikola Tesla's revolutionary ideas of 100 years ago are still making improvements to our quality of living.

Electric vehicles being plugged into charging stations? So yesterday.

According to an article on, Utah State University has demonstrated that it can wirelessly charge and power a bus transporting 16 passengers.

How did they do this?
By carefully applying a mix of modern advances in engineering and Nikola Tesla’s principles of induction, USU engineer Hunter Wu and his team have solved one of today’s vexing problems in WPT [Utah's Wireless Power Transfer team]....

“Current battery limitations prevent an all-electric transit bus from operating all day from an overnight charge. WAVE solves that problem by charging the bus wirelessly during its daily operations when the bus stops to load and off-load passengers,” said Wesley Smith, CEO of WAVE.

“This technology makes electric buses competitive with their diesel hybrid and CNG counterparts.”

The bus powered by wireless technology, dubbed "the Aggie bus" by USU, has achieved many significant firsts for the future of public transportation. 
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.

“The unveiling of the Aggie Bus today is a historic achievement and a great leap forward in the science and engineering related to electric vehicles,” said Robert T. Behunin, Ph.D., USU vice president of commercialization and regional development.

“As a result of the work done by Utah State engineers, scientists and partners, EV owners and operators will now be able to simply drive over a pad in the ground to recharge their batteries, the benefits of which reach far beyond convenience.”
Nikola Tesla understood that the Earth itself was a battery of sorts.  He conducted many experiments that showed him that electrical charge could be transmitted through the air and received almost undiminished in power from what it had been when it was originally sent.  Not knowing enough about Tesla's work I cannot say with confidence what Tesla did to determine this.  But the fact of the matter is, he understood the power of wireless electricity and wireless communication long before most others did and how it could be used to benefit the masses.  Utah State University has just taken a large step in Tesla's 19th century boots toward revolutionizing electrical transportation.
