Hi stprue, those are interesting video's, we can see in them the field coils similar to Otis's setup
Searle uses half toroid cores to get force on both poles of the rollers and Carr used "C" shaped
filed cores to get force on both poles of spinning rotor cores/coils. Pulsing the field cores can
rotate the device up to speed then they can generate.
They both have spinning magnets rotating through a magnetic field, I think Searles inner ring is
magnetized as well. Which would make the field coil control a little easier,but his rollers roll around
with no restriction other than the magnetic force holding them there.
Cars device has no permanent magnets. Just steel and copper, a much better way to go in my opinion but more
engineering is involved, for such a device that is still not a concern in a factory or commercial building environment.
If Seals device is proven to work then I see no reason why Carr's method would not be tried as well.
I think they are using the same principal in a slightly different way.
These drawing attached show the planetary/solar system principal.
The coils wound onto Carr's double cone shaped rotor cores would appear as Tesla pancake coils when viewed from an end.
And may well be connected to the capacitor plates on the rotor.
I think the spinning magnets that rotate are the clincher for power production. Difficult for one of us to build such a thing
without spending a lot of money. So who wants to fund it ? Permanent magnets could be used on a Carr type rotor maybe if they
were mounted in bearings maybe non magnetic if possible, maybe a non magnetic shaft could be put into a tube magnet and
mounted that way.
OK I'm off to ebay.
