Here s a project that uses some of those dead hard drives you ve got lying around.
Ceramic tesla turbine.
It was invented and patented by nikola tesla on the 21st october 1909 at the united states patent office from experiments done in england.
The fluid spirals inwards and is exhausted th.
This test was done without preloading the bearings.
Once again this turbine eagerly is awaited.
I was blowing the air into the turbine and couldn t see what was being filmed.
Build a 15 000 rpm tesla turbine using hard drive platters.
Apologies for the camera work.
A tesla turbine is a quite unique technology.
In the tesla turbine air steam oil or any other fluid is injected at the edge of a series of smooth parallel disks.
It is referred to as a bladeless turbine the tesla turbine is also known as the boundary layer turbine cohesion type turbine and prandtl layer turbine after ludwig prandtl because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine.
The tesla turbine efficiency has increase it now has ceramic bearings and it is now close loop which makes it ideal for organic rankine cycle systems.
Further improvements have been made after plenty of r d from the last turbine.
