What you are seeing in this video is a Tesla turbine being constructed by Jeremiah. The design is complete as a model. Jeremiah is in the initial building and testing stage.

Tesla’s Turbine by Jeremiah@iEnergySupply
“Later we took it to 17000 rpm without any noticeable vibration, this is exciting because it's equal to about 34000 rpm on the small 3" turbine, at that speed our 3" turbine made all kinds of noise. It's amazing how good tesla's balancing patent works. The operating speed of this turbine will be 30-40000 rpm, but I think we will push it even further probably past 50,000 rpm. The bearings are rated for 75000 rpm and the fiberglass won't fail until around 100,000 Rpm.”

Tesla’s Turbine has the potential to decentralize electricity. It may be able to generate all the electricity for home, auto, and even replace the internal combustion engine. It is not free energy, but it is very efficient.
