(Flashback) Pakistani scientist run car on water produced hydrogen

This is about six minutes long documentary on a Pakistani scientist who produced hydrogen out of water and used it as a supplementary fuel along with diesel/petrol to run his limousines. The water produced hydrogen not only enhances power of engine but also reduces sixty percent consumption of available petrol or diesel. But he is facing threats allegedly from oil cartels whose extra ordinary profit margin in import of fuels could be at stake if this techology is produced at a industrial scale.
