This is v2 of my Tesla turbine, major improvements/changes are the use of HDD platters as disks and the addition of ball bearings. Hopefully the Improvements make it viable. I have access to a printer now, so I'll test it soon.


  1. Print it.
  2. Thread the box for whatever you plan to use to pressurize the turbine.
  3. Put half of the disks and spacers on each half of the shaft.
  4. Attach the two halves of the shaft together.
  5. Put the 8 ball bearings on one of the caps and put the shaft on.
  6. Thread the bolts through the holes on each corner and attach the box.
  7. Put the rest of the ball bearings on the shaft.
  8. Put the other cap on and thread the nuts on to finish the turbine.

make sure it's ok with Jambo.

I can make one for you, 20 bucks 10 buck for Jambo., + postage

You can pay me at PayPal.

Hey could I get someone to make one of these and I can pay you for it? How big is the model?

Looks interesting. Could you provide an example of how the input and exhaust would look?

Why 16 brearing-balls and not just a ready-made 608-bearing on either side?

Mostly just because I wanted to, but also because 8 1/4in bearing-balls are about 60cents versus 3 bucks per ball bearing(from McMasterCar, not the cheapest, I know). I want to develop cheap printable ball bearings as well. I think parts could be built like this 90% of the time. This weekend I'm going to print one out and get some ball bearings to test it. If it works well I'll make a post for my ball bearing design, in metric rather than imperial.

Jamo - in reply to Guest

that was me, I just forgot to log in.

Terrific upgrade!
I think I will try and laser cut the parts that would otherwise demand "excessive" plastic (box parts).
I've wanted one of these for quite a while now.

Thanks, the ball bearings are captive between the cap and the shaft parts. What I mean is that the ball bearings are not a normal sealed bearing but rather just bearing balls in between the parts, so you would have to find a way to machine the raceways. On the other hand a laser cut version could be clear, which would be awesome.
