To be honest, I had never heard of this. So I asked a few colleagues: May I have some comments on this, please?
Here is the dialog:
From Bill Moore, EV World: The issue here is COST. This will work if it’s incorporated into a dedicated toll-road like the bypass around Denver or from DC out to Dulles. Feds, states and cities just won’t have the money to tear up streets and roads and embed this technology. I see a tough road ahead in the US. It’s more likely to make sense in China and India where they are building new roads. America is just too broke.
My response: Yes, I’m sure it’s pricey to install; I wonder how much per mile, and what the efficiency of the charging is. I would think another issue would be billing the energy to the consumer. And aren’t there safety and other feasibility issues with electromagnetic fields that powerful? Having said all this, one such lane in each of a city’s major freeways would be a huge step in the direction of charging ubiquity.
From Bill Moore: Exactly…. you pretty much hit them all. I am going to comment on this idea in Currents (on the EV World home page)
From: Douglas S. Wilson of ECO-Holland: Stationary induction systems will be feasible before roadways are built or retrofitted with such systems. I could see consumers’ garages and specific parking spaces at businesses or city parking lots could have induction systems embedded. A matching induction pickup coil could be built in or installed aftermarket to any electric vehicle. I think it’s a great idea. (Asks another colleague) Gary, How much power can be transferred with standard household voltages. How does the distance between the active and passive elements affect rate of energy transfer?
