By supporting nanosilica particles on sliding surfaces, water as a lubricant forms a boundary film to produce ultra-low friction, creating a water lubrication system that is both carbon neutral and energy loss reducing.
See the smooth rotation of the water lubrication system here.
Left: Weight, Right: Rotation mechanism
The shape of the weight and rotation mechanism will change.
Pour water into the rotating mechanism. When pouring water, use the above method.
Install a weight on the rotating mechanism.
Hold the weight part and rotate it a couple of times to the left and right so that the water fits into the rotation mechanism.
If you turn it vigorously to the left or right, the weight will rotate smoothly.
You can see how smoothly it rotates.
