1. No, we cannot have zero friction surfaces. ... We can reduce the friction but we can never reduce it to zero because every surface will still have minor in them. A frictionless surface is not possible is not possible because the surface cannot have a zero friction surface.
2. The use of ball bearings or lubricants is the only solution to this problem, which reduces the friction and prevents the wastage. The bearings are used in many daily life applications, like the circular movements of the kitchen blenders, gym equipment's, fans, washing machines, water pumps and bicycles.
