A group of techno-curious Probians gathered at the Toyota Hydrogen Dealer Education Facility this week to learn more about this most common of gases. School holidays meant that we had Andrew, the head honcho to show us around and share his knowledge.  In the most convivial of Q&A sessions we looked over a Toyota Mirai car, models of batteries and fuel cells, compressors, generators and a retail dispenser. It was bitterly cold outside but food for the brain within. We all learned something.
