100% frictionless bearings are not possible. "Nearly Frictionless Bearings" are a certainty with the correct engineering. Since the 1890's Nikola Tesla had been designing and manufacturing contact free machinery that produced high vacua which gave him machinery that had almost frictionless operation. He is quoted in 1895 stating his mechanical oscillator was 99.75% efficient. In that article Tesla states "we do away with all mechanical frictions".

100% contact free bearings are possible and although expensive in varying degrees they already exist in off the shelf and custom formats.

Our team endeavors to engineer a new species of contact free bearing that can hold a load at 0 RPM and then go up to a higher RPM than any other existing bearing, whilst maintaining stability.

Join us in our journey to liberate wind turbines, water wheels, windmills and other machines using bearings that produce "NO HEAT".

Nikola Tesla was 100% on this train of thought and in his 1916 work on a turbo dynamo I found a advertising flyer he had kept for a specific sort of bearing material.

Ever get a feeling that if an invention was too good, it somehow disappeared for good?
