You could fill libraries with what I do NOT know about physics (in fact, they have already done so). But I do get the concept of a capacitor as a storage device, not an energy generation device. It cannot provide more energy than has been stored in it (unless somehow it has turned into a fusion reactor). So even assuming some of the claims about the super-efficiency of this device in storing and releasing energy are true, there is still going to be the limiting factor of putting sufficient energy (electric current) in it to begin with. Can the average household outlet supply enough current in 5 minutes to power an electric motor-driven vehicle for 500 miles? I don't see how.
