I think that the magnetic field generated by car charging stations will be quite a lot and can be felt at a distance, though not sure of the details. Can it be a hazard for human as we have seem in High voltage transmission wires?
Also, what kind of power transmission efficiencies can we expect by these systems?
@larrym99: Wireless charging is good, especially because the cables that come with chargers tend to get snapped after a couple of months, and wireless means that we don't have to spend our money buying cables. Secondly, a wireless charging dock in the car would be a great feature.
I've never been all that excited about wireless charging of cell phones. It seems marginally useful to me, more of a gimmick than a really useful feature. I must admit, however, that I like the idea of a wireless charger for an electric car. That seems like something that would be more appealing than having to remember to hook up a cable every night and remove it the next morning. Granted, this is not a major operation, but I would seriously consider buying it.
As a child who watched a lot of NASCAR (or, rather, was subjected to too much NASCAR), I'm slightly sad at the prospect of cars charging wirelessly on the track. Watching the pit was one of my favorite parts - at least something happened there besides driving in circles!
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
