I have a mechanical and electrical engineer friend who has created a car running on hydrogen fuel created by zinc platter and water. The only thing is that he is reluctant to make it public although I have seen what he has done. If this gadget were to put into all our cars it will be incredible. Zero pollution and no revenue for the Government. Any fuel running on petrol will be redundant and the end of oil exploration and also less pollution by petrol or diesel cars. Any industry related to oil will be out of job which I guess that is partially the reason my friend do not want such things to happen.
