Good point Eric. I saw a short video and the fan blade was tiny. About the size of a large model plane prop. I would guess a couple of watts, but it is difficult to determine.
We need good data to evaluate the Yildiz device.

This calculates out to: 512kJ;5hour?W (512 * [kilo*joule]) * (5 * hour)^-1 ? watt = 28.444444 W That's just about enough to run a little fan. According to this link, a ceiling fan running at low speed consumes 24 W [1]. I have not seen the magnet motor video, but assuming the fan is smaller and has less mass than a celling fan, I think we can scale down the power consumed linearly using the ratio of the estimated masses of the two fans.
