The car world has long been a slave to the old fashioned barrel of oil refined into either petrol or diesel. However there has over the past decade or so been a lot of talk of a hydrogen fuel cell car as the car of the future. This technology is so advanced that the simplest way to explain it is to say that the car is powered by electricity produced through combining hydrogen with oxygen. This most jaw dropping and amazing concept results in a car that, instead of emitting harmful gases and smoke, emits water, at worst. There is a hydrogen fuel cell car in operation in California where re-fueling stations have been put into action. Unfortunately the technology for harvesting the fuel and supply chains to provide it are currently letting the side down and so it will be a long time before we see these cars as common place on Irish roads
