If your product is a battery, why not completely replace the car battery with it? How exactly does it work? I'm assuming you've already patented it, so there should be no harm in revealing more. If using one of those magneto-mechanical devices of yours reduces energy consumption by 70%, why not use two and reduce it by 91%? Or four to get a 99% reduction? Edit: The sibling comment raises a good point about bicycles. The cyclist is already acting as a motor, so just put your battery between them and the wheels. Then you can reduce how hard they need to pedal by 70-91% percent easy, right? In fact, you could just buy an electric motor, put your magnetic battery after it, and have it turn a generator. Since the motor would be using 70% less energy than normal, it and the generator wouldn't even have to be very efficient to output more power than you put in. Then you can just plug it into a wall socket and sell electricity back into the grid... Or you could divert part of the output power back into the electric motor, so you wouldn't need any power from the grid at all. You'd just be outputting clean, free electricity...
