I reviewed the reference with interest. Nothing really new here as these proposals have been around for some time, at least since the oil crisis of the early '70's.
One can make a simpler design than this by using electricity to spin up a flywheeel and use the kinetic energy to power a vehicle. But you still have to "pay the piper" 'cuz it takes another energy source to provide the initial power. While the vehicle is pollution free, you still generate pollution in producing the power to provide the vehicle energy source.
I'm reminded of proposals to us Hydrogen fuel to power airplanes to reduce greenhouse emmisions. We did studies on this and just to have enough fuel to run LAX would take sixteen 500 Megawatt nuclear plants! And to top it off, one of the combustion by products, water vapor, is also a greenhouse gas! (Because of the high combustor outlet temperatures, you also get oxides of Nitrogen which are not good.) But I digress. My point is the usefulness of these kind of devices is very limited and very few make it to the market place, not because of some conspiracy of OPEC, the oil companies, etc, but because they are not widely useful. But maybe someday.....
