According to this excellent article in Forbes, electric highways being tested in Sweden will soon be developed in California as well:
In California, Siemens has signed almost two years ago a contract with the South Coast Air Quality Management District to demonstrate the system. It took a while to turn this commitment into reality, but the company is currently installing a two-mile long overhead contact line system for hybrid electric trucks near the ports of Los Angeles and Long Beach, two of the largest such facilities in the country.
“The economic logic of the eHighway system is very compelling for cities like LA, where many trucks travel a concentrated and relatively short distance. Highly travelled corridors such as this are where we will initially see eHighway being applied,” said the president of Siemens Mobility and Logistics division in the U.S, Matthias Schlelein, at the time of the announcement.
The tests will be conducted in California throughout 2017.
