Surely...
...If this tech were placed under the tarmac of roads, any time a car was on the road it would be charging.
I see a number of benefits that come out of that:
* maintains cerntralized power generation (More efficient surely?)
* you wouldn't need such big batteries in leccy cars. Just a bit in case a cell or two was out or to drive off the network for a bit.
* almost impossible to run out of fuel on the motorway
* could maybe use the motion of the car to extract more energy (Moving faster thru the field or something)
* taxing would probably be smarter and could be based upon energy used for each trip (A function of distance AND speed) without the need for cameras etc
* Just park as normal to charge.
* Low size, low power bolt on pickup and motor for a bicycle may be feasible (The flat pickup could fit in the space in the frame and doesn't look heavy) to provide assisted power for hills etc.
In fact, if the road powering cells are smart, then surely an autopilot system of sorts (Maintaining a good distance from the car in front) would be easy as it would automatically pass less power to the car behind if the car in front slowed.
And why limit it to roads? Do the pavement too. Power for laptops, run a net conn to it to, mobility scooters could get power from it, street sweepers, all kinds of uses.
