Sid; I suspect they might not be good for sports cars, but the bus niche is promising. I will look up Rosen and see what went wrong. It could be the suckering of a rich man by people who like to drive mercedes. Did anyone ever look in the Rosen parking lot? Count the fast cars, and you count the waste in excess wages etc. Did they have a web site.? I think flywheels can be safe and effective, it just takes the right development to perfect them. Bill

Sid One also has to carrry that heavy flywheel around. I bet the amount of energy carried per unit mass of gas, hydrogen methanol is a lot more than a flywheel. Don

Information on Rosen Vehicle Flywheel. The following is an excert from an article called "Rosen Cavalier" in the January 18, 1997 edition of the Econmomist magazine. "A reliable flywheel is fiendishly difficult to design and build. The Rosen version weights 20 lb and has a diameter of 19 inches. It is made from 4.5 miles of carbon fibre ribbon precisly wrapped and bonded about a titantium hub. When spun up to its cruising rate of 55,000 rpm, its edge is moving at about 1 km per second-around three times the speed of sound. And, because it is operated in a vaccum, with frictionless magnetic bearings, it can spin for six weeks without slowing down so much that it cannot do its job."
