>2) while it says "runs on water", the guy is careful to label all his machine as "HHO", i.e. two hydrogens and one oxygen, i.e. he first performs electrolysis of water... which needs to consume energy first, and which is not clearly shown.
So, the hydrogen is basically used as energy storage.
In this case, the energy itself might be produced in several different ways, many of which are not possible, or perhaps just not practical, for packing into a car, like solar energy, tidal energy, nuclear energy (fission, or fusion once it becomes available), etc.
I have seen other concepts for energy
storage; one is to have a heavy rotating wheel. This seems to be feasible for medium-sized vehicles, such as buses.
Regular batteries seem to have too little energy density, for now.
