What's the basis for this? Also, sometimes in accidents the gasoline does mix sufficently well with the air to be a hazard (remember the Pinto?) I'm certain that in a flywheel powered car there wil be accidents that will be explosive and many that are not. Isn't this a factor of the design? If the flywheel power source is a viable and marketable option I'm certain that manufacturers in lawsuit happy countries like this would make a couple of prototypes and run 'em into walls to see what happens. This technology is relatively new, gasoline powered cars have been around for a century or so and there are still problems. Maybe the flywheel isn't safe. Could it be used in a smaller capacity to augment accelerations from braking energy? All of this discussion is conjecture, but aren't ideas wonderful to ponder? Brian Barkey
