ORBO Debuts Tomorrow

Skyhunter

This is not a permanent magnet motor. It is more like a pulse motor

Their site has a number of experiments to demonstrate that they have eliminated the drag from counter EMF. The final experiment will be shown today.

Check it out.



Thanks. link fixed.

Might need to clear your past buffer. Don't think that's the link you wanted for ORBO.

You should look over this series of experiements replicating Steorn's work, but with better explanations of the results:

Evo

Is the Steorn crackpottery a banned topic?

Proton Soup

it looks to me like their motors are doing negligible work, anyway, which would translate into negligible back EMF, no? sure, make everything slicker 'n shinola and very light with PTFE, keep most of your magnetic flux in the center of that toroid so that it's really not well-coupled, and then act all surprised that you can't see anything. negligible coupling, negligible inertia, and negligible load = failed experiment.

thing is, you never know if these guys are really con men, or just stupid/unedumacated. used to be, they would fool themselves because they didn't understand something like how to computer RMS, or the limits of their instrumentation. maybe when someone does a coherent writeup of why this thing is a failure, you won't see much of it anymore, either.

There is no need to address this in S&D because it can easily be tested and the results published.
