Bulk high-temperature superconductors are being considered for use in several engineering applications, including passive magnetic bearings. These bearings, apart from being passive, i.e., inherently stable, also offer the promise of lower bearing lo

Installing an energy recovery system (ERS) on a mining haul truck has the potential to save a significant amount of fuel by recovering energy while descending into the pit and reinjecting this energy to reduce fuel usage for acceleration and ascent o
