Wireless Trams

No, not that sort of wireless (though that will surely follow). Kawasaki HI are getting ready to unveil streetcars that will run on rechargable batteries instead of drawing their juice from overhead cables. The nickel hydride batteries are ‘old tech’, a tried and tested workhorse, meaning that there’s no conceptual vaporware involved in this project to stall its progress. Of course the electricity to recharge it will still have to come from somewhere, but cutting down on urban emissions is still a good step forward.
