fake......vehicles cannot run on water by doing electrolysis...... you require around 240 kJ of energy to break water molecule .... and when u combine H2 and O2 in 2:1 ratio you should be able to get water again and 240 kJ of energy in form of heat .... so if u achieve 100% efficiency ... u simply converting electic energy to heat energy through medium of water...... but in practice you can only achieve proper combustion if u have H2 and o2 in ratio of 5:1 so there goes effiency from 100% to around 50%....... and in this 50% also we get it in form of heat.... so actual usage of that heat to get wheels turning will be 25% of that 50% in best case......... so the actual Efficiency you get in this vehicle is 6.5% ...... but instead if he uses full electric engine cutting all this on board electrolsis crap .... He can achieve an efficiency of 80-90% ........ So we can easily say that water fueled vehicles are fake..... and not viable unless you find very very cheap and easy way to break water molecules using very less energy .....
