Pupil transporters don't often find themselves in an office on the 33rd floor, but they want hybrids and they may have to prep to get their yard ready for hybrids. In Napa Valley, Calif., Ralph Knight had to change his power breakers from 110 volts at 10 amps to 220 volts at 30 amps to enable a four-hour rather than eight-hour charge. But Knight already had the charging stations set up from his experiments in all-electric school buses. What would it take to get your yard up to snuff?
