There is talk about embedding electric charging infrastructure in highways to allow vehicles to charge while driving. The search results provide several examples of this technology being developed and tested:
- Researchers at Cornell University are developing technology that can charge electric cars while they are in motion by embedding metal plates in the road that create alternating electric fields to power the vehicles.
- Sweden is building the world's first permanent electrified highway by 2025 that would enable electric vehicles to charge while driving. The technology uses a conductive charging rail embedded in the road that transfers electricity to a receiver on the vehicle.
- A pilot project in Milan, Italy has successfully demonstrated inductive charging technology that powers electric vehicles from coils embedded under the road surface while the vehicles are in motion.
- Similar electrified road projects are also underway in Germany, Sweden, Israel, and the US state of Michigan.
The key benefits of this technology are that it could allow electric vehicles to have smaller batteries and eliminate the need to stop and charge, making them more convenient and practical for long-distance driving. However, the high costs of retrofitting existing roads with the necessary infrastructure is seen as a major challenge to widespread adoption.
