Hydraulic hybrid drivetrain gets on the school bus

Anyone who's read my blog or even some of the articles I've authored over the years knows that hydraulic hybrids are one of my favorite topics. Mostly because as a non-engineer, I can truly grasp how hydraulic hybrid drivetrains work and I can truly see their benefits in the real world. I see a hydraulic hybrid drivetrain as much more useful, efficient, and cost-effective than a battery/electric hybrid ever well be....More
