Electreon wireless' electric roads in Tel Aviv to charge cars on the go

Why would you ever want that. There isn't any added benefit. There is a reason EV have shielding around the battery pack. Now they want to beam it under the car? This will just add time and money to road work and make maintenance harder and more expensive. It's not efficient like normal charging and if we were to go completely autonomous "normal" charging via plug is much more economical, faster and safer.

It seems dubious to me, too, but as a solution for electric buses, I think it makes more sense. It allows you to avoid heavy/expensive battery packs, long charging times, and unsightly overhead wires.

Efficiency is an open question, though.

I'll put my money on advances in high capacity batteries and faster charging.

Changing your whole infrastructure seems very wrong to me. Imagine if there was an issue with one of the substations suppling power to the area or a blackout, your whole public transport is going to shutdown seem like a strategic failure to me.

At least with current EVs you'd still be able to drive or power your home.

Agreed about battery tech. I wouldn't bet against it.

But there are cities that already have electrified buses (such as Seattle). This could potentially make sense for a city investing in adding or expanding such a system. If the choice is between hanging wires or embedding coils in the street, it may make more sense to embed the coils.

Not one word on efficiency. Inductive charging is normally pretty inefficient, I would imagine at speed even less so. Seems like it would never be cost effective to do this.

it can't possibly charge them efficiently enough for it to be relevant
