Researchers at Aalto University have tackled these problems, developing a power transfer technology that works regardless of the position and orientation of the transmitter and receiver. The key idea is to arrange the transmitters in a grid with the current in neighboring transmitters running in opposite directions – for example, a clockwise loop in one transmitter and counter-clockwise loops in its neighbors.

Renewable electricity generation, done.

Renewable power storage, done.

Power delivery to moving ground vehicles, done.

I have my doubts about the last two. You also need billing to match the last.

Without billing, more of a useful industrial automation technology than anything for the public space.

The transmitters are triggered by the receiver, billing is easy:

Because the presence of a receiver triggers the power transfer, the system can work without any positional tracking and communication between the receivers and transmitters. This also means that power is only transferred to the receiver, rather than the entire area being energised, and it makes it possible for several devices to be charged simultaneously.

Tiling transmitters together produces a charging area of the desired size and shape. A subset of the transmitters is then activated at lower power. ‘That’s basically a search – the transmitters are listening for a receiver,’ explains Shamsul Al Mahmud, a doctoral student in the project. If power transfer to a receiver begins, the neighbouring transmitters switch from being off into an alert mode, primed to transfer power if the receiver appears over them.

Yes but microwave transmission of mw of power will heat the atmosphere worse than CO2 and methane.   There is this issue of vibrating electrons. Jay you are old enough to Remember Border Radio, XERA,  and Wolf Man Jack or WJS Chicago, KOMO in OKC  or WFAA in Fort Worth, WWL New Orleans.

The problem of increased electricity supply is the main issue IMHO though. I can see that boulevards with wireless charging would be quite helpful. Most drivers can get close to their destination on the main streets of any town.
