- How big of a container are we talking about in this flywheel thread?
-
- I have heard talk of flywheels that contain enough energy to move a
- car from a standing start (?) to 100 mph. This seems like a tremendous
- quantity of energy from a spinning device.
-
- I assume that a flywheel is cylindrically shaped. I have only heard
- descriptions of what they do and that they make EV's more competitive
- with gasoline-powered cars. I have never seen a technical drawing.
-
- I'm not even sure that they exist at all. Are any regenerative flywheels
- in use today other than on test vehicles that cost hundreds of thousands
- of dollars?
