There is a new paper written by academician Veljko Milkovic:


Oscillations More Efficient Than Rotation

Energetic Superiority of a Pendulum Versus a Wheel in Stationary Machines

The wheel is probably the most important invention of all times, present in almost every machine, and contemporary constructors still relay on all its versions…
According to present findings the first pottery wheel was made in Mesopotamia 5,500 years ago. A wheel with spokes was found 4,000 years ago and in the course of the time there will be countless number of fanciful constructions similar to the wheel or wheels. The flywheel, i.e. massive wheel, is used for stabilization and accumulation of mechanical energy, and belts and gears for transmission...
Similar form is accepted as the best solution, widely found in motive devices as turbines in electric power plants.

The shape of the wheel should not be accepted as the best solution because oscillations of a pendulum lasts much more time, and we will examine it next...
