Rick Crammond has found a way to improve the Tesla turbine design and give it an update that can sharpen pencils at 2,200 rpm. That's some fast cranking. The turbine alone can reach speeds of 8,000-to-12,000 rpm before it self-destructs. So, Rick built a "bullet-proof" containment box. The turbine, which requires no bearings or shafts, runs on compressed air and spins a pair of disks magnetically coupled to the sharpener.
