"Tiny Orbo Replication" over 100% efficiency

[PaulLowrance]

That tickles my curiosity.
Can you show some of your DSO measurements?

Sure, soon enough I'll show lots of measurements on video.

Hi mscoffman,

You mean decrease the rpm? Sure, that's easy by lowering the voltage. The stage now is the find ways to decrease the losses so get a self-runner.

Steorn is using plastic, which is probably what I should eventually use, or some type of ceramic. What would be the hardest, yet affordable, plastic or ceramic?

Yes, to scale back the internal energy, without changing circuit drive
characteristics. Plastic is machinable, Ceramics are stronger, plastic has
larger thermal expansion characteristics as Steorn found out in his first
attempts. I kind of like glass for a PM machine. One would slide the guts
of the device into internal slots, once one knows what he is doing. (and
can afford the thermal molds.) They are satisfying for MIBS to smash,
and yet you can always reach around and pull out another one.

Any ideas where to get the lowest friction bearings? A hard drive?  VCR?  CD player?

[PaulLowrance]

These guys claim to have the best low friction bearings, but don't see any price sheet,
