The technology is almost ready for prime time.
Imbedded inductive chargers a health hazard for anyone with a pace maker or other implanted device. Federal safety regulations limit the power output of both in ground or over head charging units in public places where people might walk over or under them.
This power restriction limits the effective range of recharge to just a few inches. Efficiency decreases with increasing distance between elements. Boosting power helps to a point, but makes them more dangerous to people with implanted devices.
An under vehicle charger where a person with an implanted device might drive over brings up concerns over proper shielding of the under carriage to protect the driver because the driver is closer to the ground than walking over a charging pad.
An increasing number of implanted medical devices are recharged using low power inductive charging. This advance in medicine makes them more vulnerable to strong recharging fields than older implanted devices.
This safety concern has been the downfall of all attempts at imbedded or overhead recharging of EV???s.
Progress is being made in improve efficiency at greater ranges and lower power levels. It is almost there.
