(reposted after logging in from anonymous coward status) I was in Shanghai in January, and observed supercapacitor (as labeled) buses operating on major routes on-loading and off-loading passengers. Overhead cables lined the route, and at every stop the bus would extend a superstructure to the cables, make contact (whether directly or inductively - unobservable), wait 5-10s, retract, and onward the bus would go. I don't know who manufactured the buses. I simply thought it notable that the Chinese were fielding such a system. I'll leave the questions about liability, etc. to the floor. In any case, and irrespective of where the bus was manufactured, guess who's going to learn whatever shortcomings may lie in this technology and improve on them first for having deployed it. And if the buses were designed or made in China, then . . . props to them.
Not trying to create xenophobic bogeymen here, quite the contrary, it's worth observing how different folks operate.
