Abstract
A kinetic energy storage device includes first and second counter-rotating variable flywheels coupled to a differential. A control mechanism coupled to both flywheels allows the moment of inertia of each flywheel to be adjusted so that the flywheels, differentia, and control mechanism operate as a true infinitely variable transmission. The differential includes an output to allow kinetic energy to be extracted from and added to the device. The counter-rotating flywheels provide stability and controllability making the device suitable for use with short duty-cycle vehicle motivation. Also disclosed is a vehicle drive train configured to be driven by said kinetic energy storage device and a fixture for providing initial kinetic energy to the device.
