The motor itself will hold them, you just need to attach the motor to something. Unfortunately, I don't think HDD motors will actually generate anything, so that poses another issue.

As someone mentioned before, the Tesla Turbine's efficiency drops severely as it gets loaded down. Since it relies on the surface tension of flowing fluid to power it, instead of mechanical force (yes, I know, surface tension is a mechanical force), it doesn't respond well to changes in either input or output.

This is why I never mentioned it, even though they're one of my favorite study subjects.
