Rechargeable Lithium Battery Powered Street Car

Rechargeable Lithium Battery Powered Street Car

A streetcar that recharges itself during breaking, eliminates the overhead wires commonly found on modern streetcars. This technology could improve and eliminate some barriers from streetcar’s in modern city public transportation.

The Railway Technical Research Institute in Kokubunji, Tokyo, has developed a streetcar powered by a lithium battery that can recharge in under a minute. The institute will start conducting test runs in Sapporo at the end of November to check the streetcar’s capacity. Powered by the onboard battery, the vehicle runs at a maximum speed of 40 kph for 15 kilometers and is capable of converting 70 percent of its deceleration energy into electricity, which it sends back to the battery. The rest of the power is supplied by recharging stations, where the streetcar connects its pantograph to overhead wires.

Concept Car: Lincoln Mark VIII With Folding Doors

lincoln concept car

“Lincoln executives were concerned about the heavy and wide doors on the Mark VIII in the early 1990′s especially in large cities with tight parking spots. They were toying with the idea of a Mark VIII that had doors that disappeared beneath the car which would require no additional space for the doors to swing open in order to allow the occupant to exit or enter. Back in the day, the major auto makers would sub-contract their concept designs to other engineering firms who specialiazed in auto concepts and executions. In this particular case, this Lincoln Mark VIII was shipped over to Joalto Design Inc. near Detroit…who created this amazing, one of a kind concept car and shipped it back to Lincoln for executive approval…Unfortunately, the Ford Motor Company executives did not like the design and ordered the car (and the concept) to be sent to the junkyard and destroyed. The current owner had been tracking this car for nearly 20 years and finally convinced the previous owner to part with it.”
