Publisher Desc.  The flywheel is turning fast and steady, thereby energy is stored. If its rotation changes, the energy begins to flow. Speeding up absorbs the power, braking leads to a release. Force is needed for momentum, but once the halt is overcome, the wheel is ready to provide. As well the gyroscope performs according to the same effect - standing, turning, keeping balance - like a floating dancing couple on the parquet floor. They soak impetus from three quarter time of music. Once turning to the right, then turning to the left and energy restarts to flow. Flowing, streaming, even carrying somebody else along. Totally infused with power, everyone is finally fulfilled.
