A drive device with multiple swinging blocks drivingly connected with each other includes a driven unit connected with a driven apparatus (such as a power generation motor or a generator), a driving unit drivingly connected with the driven unit and an actuating unit connected with the driving unit. The driven unit includes a flywheel. The driving unit includes three dynamic energy modules respectively connected with the flywheel at intervals. Each dynamic energy module has a gear engaged with the flywheel and a swinging block disposed on the gear. There is a 120-degree angle difference between the corresponding angular positions of each two adjacent swinging blocks. The actuating unit includes an actuating motor, a driving member driven by the actuating motor and connected with one of the dynamic energy modules and transmission members drivingly connected with the dynamic energy modules for driving the driven unit to together rotate.

An example flywheel energy storage device includes a fiber-resin composite shell having an elliptical ovoid shape. The example device also includes an axially oriented internal compressive support between the axial walls of the shell. The example device also includes an inner boss plate and an outer boss plate on each side of the shell. The example device also includes a plurality of radially oriented, fiber-resin composite helical wraps forming the shell and coupling the shell to the inner and outer boss plates for co-rotation and torque transfer. The example device also includes boss plate attachments on internal boss plate supports to mount the shell for co-rotation and torque transfer via resin bonding, friction, and compression between the inner and outer boss plates.

A gyroscopic roll stabilizer comprises a gimbal having a support frame and enclosure configured to maintain a below-ambient pressure, a flywheel assembly including a flywheel and flywheel shaft, one or more bearings for rotatably mounting the flywheel inside the enclosure, a motor for rotating the flywheel, and bearing cooling system for cooling the bearings supporting the flywheel. For smaller units, the bearing cooling system is effective to enable a flywheel with a moment of inertia less than 11.7 kg.m.sup.2 (40000 lbm in.sup.2) to be accelerated at a rate of 5 rpm/s or greater. For larger units, the bearing cooling system is effective to enable a flywheel with a moment of inertia greater than 11.7 kg.m.sup.2 (40000 lbm in.sup.2) to be accelerated at a rate of 2.5 rpm/s or greater.
