California to test eHighway

An overheard electrical delivery system for trucks developed by Siemens is about to come to California.
Called eHighway, it is a series of overhead cables similar to what electrified trains use. These overhead electric cables are used by specially designed hybrid trucks to power them as they move,  reducing fuel and noise emissions on heavily traveled stretches of highway.

Because the trucks are hybrids, though, they can easily disconnect from the cables to leave the highway and reach their destination. The video shows the trucks can connect and disconnect from the cables while on the move. The pantograph, which is the thing connecting the truck to the cables is designed so the vehicle can naturally move around within its lane without disconnecting.
