  Great question – at the moment I have produced some fuel but it is a long way away from being usable in a car. I’m hoping that as I do more work I’ll be able to make it more efficiently and then there might be enough to power a small vehicle (toy car!)
  
  As it is research I work on a small scale until I know what will work the best to save money and material.
