Its explained in the YouTube video, "Steorn Orbo Technology Launch 2009"
The lower two rotors are a motor with PMs on the rotors and small coils (electromagnets?) on the stator. The EMs obviously require some DC electricity. The topmost rotor is a small generator which produces AC. To charge the battery they run the AC thru a "very simple rectification circuit". So, yes, the motor part does require power, but apparently (much) less than they can generate, so it should be easy to demonstrate that this thing could be kept running for weeks, months when it should draw down the battery in a matter of days... -Mark -----Original Message----- From: Craig Haynie [mailto:cchayniepub...@gmail.com] Sent: Tuesday, December 15, 2009 7:53 AM To: vortex-l@eskimo.com Subject: Re: [Vo]:Steorn Demo > ...

We on this list, are indeed patient, but there are smoothing circuits and capacitors which could take the power from the generator and turn it into the equilibrium of a battery.
