I am having a difficult time judging the amount of energy stored in these magnets. I recall almost having a finger removed when holding a piece of steel near a powerful rare earth magnet. The force attracting the metal was very large and worked against my muscle power. I do not know how many joules of energy were released by the magnet as it drew the steel near to itself, but it was significant. I assume this process could be repeated many times with additional pieces of steel until the field was hidden within the metal mass.
If you take that amount of energy and multiply it by the number of magnets in the device, you obtain a fairly large amount of energy. I would certainly expect this amount of available energy to be capable of overcoming the losses due to friction in bearings for a very long time. The energy extracted by a fan would need to be handled as well. I am not suggesting that the Yildiz motor is a fraud, but I suspect that there may be another explanation for its performance that is more "down to earth". :-) Dave -----Original Message----- From: mixent <[email protected]> To: vortex-l <[email protected]> Sent: Sun, Apr 14, 2013 5:53 pm Subject: Re: [Vo]:Yildiz motor in Geneva -- ran 5.5 hours then broke down In reply to David Roberson's message of Sun, 14 Apr 2013 01:29:19 -0400 (EDT): Hi, [snip] >Has anyone figured out a theory as to where the energy comes from to drive the motor? Are the magnets depleted with time? I think you can get a measure of the maximum energy stored in the magnets by multiplying the MGO of the magnet by its volume. Even for very strong magnets, it's a pretty small number. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
