Maybe it's not your intention, but your comment seems to imply that it's too difficult to attempt because of how much copper would be involved. However, I suspect you wouldn't need to purchase all the copper up front.

You'd be aiming for short runs off of existing power infrastructure and you'd be scaling up over time. You also wouldn't be running these to every single place that a car _could_ park, just trying to get a critical mass of them near where people live.

Most people already have lots of copper cabling in their houses and most cars are parked overnight near to residential housing, so the additional copper used would only be some fraction of what is already in most homes.

I remember someone did an analog British Telecom. At the time, BT had a market cap of something like 30 billion pounds, and the estimated value of all their copper wiring was around 50 billion pounds. The (amusing and not thoroughly convincing) argument was that take away the copper, and BT was worth -20 billion pounds. Maybe with all that legacy copper, someone will start a copper mine in the UK.

not very many. most streets already have power lines. you just need a few extra feet to get to the car.
