Germany has opened its first-ever section of "eHighway," which allows hybrid cargo trucks to charge their batteries while they are on the move. 

The program, called Elisa (electrified innovative heavy traffic on the Autobahn), is an environment-ministry-sponsored project involving the electronics giant Siemens and authorities from the state of Hesse, where it is taking place. 

The trucks — which have conductor rods called pantographs added to the top of the cabin — must be going less than 56 mph to successfully make a connection.
