No, it has to be less efficient...wireless radiates in many directions (even if you use resonance like in this case), you have to be a right place with teh reight surrounding for an optimum energy transfer...it is more effcient with wrires for sure, the only question is by how much...Kris

I dont even have wireless chargin in my phone now. Why dont they first do it for phone and then think about the EV hybrids? BTW like Kris, I am bit skeptical about the conversion efficiency.

Qualcomm does not provide much engineering detail but seems to indicate that wireless charging can be much the same as conductive charging but with the benefit of not having to connect up the car.

Thank you Mark for pointing this out, here is the link for others to enjoy: http://www.aesopinstitute.org/moving-beyond-oil.html I need to point out the obvious though: the energy used for charging wirelessly those EV cars will have to come from somewhere! so saying "moving beyond oil, fossil and radioactive fuels" is a bit premature to say at least...Kris

See Moving Beyond Oil on the Aesop Institute website for a 5 minute electric car charging system under development at Hydro Quebec. Combine these technologies and we will have a whole new ball game!

Interesting idea of wireless charging...how efficient that charging is though? how long would it take to charge a battery?...and if you sit in car do you get to be charged too? ;-)...Kris

NEXT UPCOMING BROADCAST
Why Connect a Car?
May 11, 1pm EDT Monday
Overview: Battle-hardened veterans of the electronics industry have heard of the “connected car” so often that they assume it’s a done deal. But do we really know what it takes to get a car connected and what its future entails? Join EE Times editor Junko Yoshida as she moderates a panel of movers and shakers in the connected car business. Executives from Cisco, Siemens and NXP will share ideas, plans and hopes for connected cars and their future. After the first 30 minutes of the radio show, our listeners will have the opportunity to ask questions via live online chat.
