I just found out this incredible tutorial about how to build a simple electro-mechanic system that can free you from regular fuel. For the newbies in this subject, the idea is pretty simple: split the water into hydrogen and oxygen, make an even mixture and insert it into the air intake of a car’s carburetor. The main problem is that with usual electrolysis you can only put more energy into the system than you get from it. This problem is overran by using a revolutionary discovery that splits water into the two elements by using some properties of water when vibrating in a range of electrical frequencies. This method of splitting apparently exploits the zero point energy properties of water, as some say. You can build your own water fueling system by following the instructions from this link.
