Arotech Corporation (ARTX) announced today that a test drive conducted with its all-electric hybrid bus using commercially available zinc demonstrated performance similar to that achieved with the proprietary dendritic zinc used to date. Corroborating lab results, the bus achieved a range of 133 miles on a simulated city-cycle drive, similar to the range achieved a year ago in a similar test with the proprietary zinc. The system's efficiency has been improved as well. [ more ]
