Yeah, I know it doesn't make sense, and all, and the best argument against it is ever since I can remember somebody's claiming to have a water-powered car, yet nobody's ever selling one. Still...what drives these guys, I wonder. Is there any sincerity at all? Is it all a scam, or is there something there that shows promise, so they exaggerate?
They catalize water using an Aluminum oxide reaction. So, they do split water to make hydrogen to run the car.
But making aluminum (and the agent to keep the reaction going) are very electricity intensive operations. There is no net-energy gain, they are simply moving the energy where the energy is needed from the aluminum smelter to the car.
It's no different than the air-powered car - the electricity is stored as compressed air (becoming a 'battery'), moving the energy production to a power plant and away from the car.
It's not a bad thing, but they are being dishonest about some things - like the car is not 'water powered'.
