Gyrostabilizer methods and apparatus having simultaneously counter-revolving
masses that do not require physical shafts or axles. The stabilizer can have dual
counter-revolving concentric rings, or tracks filled with weights such as spherical
balls, that are propelled in orbital fashion by fluid pressure or electromagnet
propulsion. The rings can include rigid contiguous rings, such as metal, plastic,
composites, and the like. Additionally, the rings can include liquids and/or gasses.
Still furthermore, the rings can include flexible, bendable contiguous materials,
such as chains and ropes. The concentric ring diameters can be a few inches to
more than ten (10) feet. Without an axle or shaft the weight of the gyrostabilizer
is shifted to the perimeter where most of the momentum is generated at a fraction
of the weight of gyrostabilizers that spin on an axle. The gyrostabilizer can dampen
unsteadiness such as tremors, vibrations, sway, pitch, roll, and yaw.
