Tesla turbine cold steam 135f water looks promising

[JimBoot]

As a distraction/ preparation to the horror that is happening in my town at the moment I'm looking for promising projects. Thoughts on this? They reckon it's a hurricane in a box when you add heat and moisture

There is a researcher from UK whom I believe started or inspired this recent
Work , I will see if I can make an introduction for you to speak with him!
(Been quite some time since I last spoke with him)

Yes distractions towards a better world are good !

Will ring him today ( let you know one way or the other)

Good to see you around!

Thx
Chet

That's a pretty interesting video...

I used to design and build micro gas turbines, the newest turbines can easily spin up to 100,000 RPM and some can even reach 500,000.

The biggest issues are high RPM centrifugal forces on the rotor causing vibration and stress fractures. As well as bearing lubrication/heating at high RPM due to the high fluid sheer forces. Most modern micro turbines use air bearings to solve this issue. These issues become much more important if were thinking about running a turbine for any length of time.

On the Tesla turbine having low torque, as an engineer I can safely say it doesn't matter. Most of the critics are confusing work, power and energy again. In fact Work=Force x Distance, so a large force/small distance or small force/large distance can produce the same work. In a Tesla turbine the RPM is the Distance travelled and the drag on the disk the applied Force. So in the Tesla Turbine were basically taking a small force and applying it over a long distance. The distance is the circular path the fluid takes winding inward to the outlet.

The design is brilliant because most radial bucket type water or steam turbines such as a Pelton only extract energy during less than one revolution or 360 degrees. In the Tesla turbine the working fluid could act through ten or more revolutions inward encompassing 3600 degrees. Thus the distance travelled is almost 10x greater for work to be performed increasing the power output.

Thinking of using hdd platters. May need a cnc plexiglass enclosure though to hold the vacuum. I can't see a 3D print capable of that. This is just looking at the test data not the setup. See 1st vid in thread for that. https://www.youtube.com/watch?v=kzajuA1UMbs looks significant. Couldn't we repurpose an old AC?
