@NadineJ- I haven't heard yet if this magnetic wirelesses charging affect the people in the vehicle. I think it's high time for researchers look in this problem too. If so we need to keep away from a charging vehicle.

@Ann – That's good news, I just wish if these charges were wireless too. I wonder why we don't use this concept and implement it at once than having the normal charging units installed first and then upgrading to wireless charging.

@naperlou   - I've heard that there high voltage charging units reduce the life of the batteries. Most manufactures rate the stranded charging power. Vehicle manufactures need to stick to a standard charging voltage to make this project successful.

@naperlou   - As this is wireless charging we need to figure out wireless vehicle identification for billing. May be we could use an NFC tag for the vehicle to communicate the identification and the time to the charging terminal.

@Charles   - Wow it's a great way of thinking, now you could charge your electric vehicle in the same mechanism. I hope going forward we will have these charging stations at every car park, so you never run out of power.

Re: Coils of copper - tempting?

Good point, TJ. We actually discussed that question with HEVA. HEVA's position is that it will be less of a temptation than the copper wiring in a "wired" station, which is a little easier to access.

You're right, naperlou, public fast-charge stations are starting to pop up. They use 440V lines (only available in public stations) to charge EV batteries in as little as 20 minutes. These systems will connect to the grid on a 220V line and get the job done faster than a wired 220V line, but not as fast as a fast-charge station.

Coils of copper - tempting?

I really want this system to be successful - I like the concept very much.  But what temptation will the chargers be to copper thieves?  I've had customers suffer theft of copper cable (sometimes from live circuits!).  How easy will it for thieves to steal the inductor coils?

I think this would be good if the bus is charged while parked in a staging area.  It wouldn't be a good idea to charge while there are people, especially children, on the bus.  EHS (Electrical Hypersensitivity), like extreme food allergies, is very real for many people.

Here in San Francisco, I noticed that our public buses are moving from bio-diesel to bio-diesel hybrid electric.  This would be great in the bus barns to quickly and easily recharge the fleet.

Meanwhile, eight states including NY and CA are working together to boost the number of charging stations:
