I find it quite amazing that they seem to run at home for years at a time,but when at a public show they dont even run for a day without something going wrong.This seems to be the norm for all so called OU devices when it comes to public viewings or test.

Free Energy devices, like fine wines, do not travel well, it appears. Best stay at home and invite the marks, er, the interested potential investors, over to see it working in an environment you totally control, like that "other" TK fellow does.

Say Yildiz is not a Mylow and actually ran his magnet motor for over four hours from his shade tree shop. Imagine what 2000 Japenese engineers could design and manufacture fully implementing his discovery!

a lithium ion bat can definitly power this prop for weeks,even the aluminum casing if wet with electrolyte inside can power it galvanicly for weeks but would yildiz go thru all this trouble if that is the case? Madness

Well, let's put some hard numbers to it. First, the observables: we have a 16x10 prop being turned at around 2600 RPM for around 4 1/2 hours, then we have a rapidly decreasing RPM series (reminiscent of a battery running down) until the claimant stops the run. Call it 4.7 hours at 2600 RPM to be generous.

And we know some LiPo parameters. My electric helicopter uses a 3-cell LiPo, nominally 11.1 volts but about 12 something when fully charged, and the capacity is 2100 mA-H, and it's about the size of a 3 Musketeers candy bar.

And we know how to calculate the power required to turn that 16x10 prop at 2600 RPM. I got 14 Watts when I ran the calc I posted earlier, but I misplace decimals a lot so please check my work. So the 4.7 hours demo required at least 14 x 4.7 == about 66 Watt-hours of energy.

So.... a 2100 mA-H, 11.1 V battery has around 23 Watt-hours of energy in it. Is there room for three or four candy bars anywhere inside Yildiz's motor.... or the big opaque base it's sitting on?

Please check my math and let me know if there are errors so that I can correct it as soon as they are pointed out. Yes, that is a DIG at RA.

ETA: I see that I did make an error. It now seems that I am calculating 61 Watts for the power at 2600 RPM. That seems high to me but that is what the numbers are saying and I've run them several times on two different calculators. So that means we need space for 12 or 13 candy bars or something like that.

61 x 4.7 == 287 Watt-hours
287 / 23 == about 12 1/2

Hm. Check that base unit.

Here's another online prop calculator:
http://adamone.rchomepage.com/calc_thrust.htm
Using its "APC 16x10" and its default atmosphere parameters I get 46.4 Watts. More than I expected, for sure, but still a lot less than what Yildiz has advertised.
Nine candy bars.

Does anyone know where the RPM numbers are coming from? Is an optical tachometer being used? Is it counting blade passages? Is it possible that it is reading 2600 blade passages per minute, which would be 1300 RPM?

Power to turn the prop goes as the cube of the RPM, so half the RPM means one-eighth the power required. Two candy bars.

I was going to say at 14 watts for a 16 inch prop
No way !!
I don't get You tube ATM ,is the settup in the Tube?
or free air?


putting the blade into that tube with the back pressure from the other blade is analogous to placing it into water.[OK water is a bit dramatic .however the load increase will be huge.]


As will the watts required to drive it!


Since you have all the propeller  toys already TK and with all that spare "internet Time".


Some chewing Gum a couple of staples and a cardboard tube.
we could even Calibrate the little out put genny load [TinMan knows How to do that ]

I found the meter used to measure RPM's - it also can measure temperature (non-contact):
http://www.extech.com/instruments/product.asp?catid=21&prodid=16

It is seen in one of the vids from 10 April.  Note the reading - 1517 (RPM), for this run at about 3pm on 10 April.

The setup is fairly described in the quote from Sterling's correspondent above. The prop is sitting well out in front of the motor, there isn't really any shroud but when he puts the plastic box on it, it effectively acts as an "end plate". I've demonstrated how adding an endplate can actually _increase_ the RPM of a model airplane propeller at a given input power, but that's not really relevant here.
I'm happy with the 46 Watt figure that the online calculator comes up with as ballpark -- IF the RPM can be trusted. I am having doubts now, based on the sound, and I'd like to see something about how the RPM is measured: what kind of optical tach, does it correct for blade count, is it calibrated against some standard, etc.
Because if the thing is actually counting blades and not correcting, then it's indicating 2600 blades per minute and not 2600 RPM which means 1300 RPM and that cuts the power requirement by a factor of 8.

You are kidding, right? OK, that thing has no correction for blade number. Where on the motor is he measuring the RPM? If it's at the blades.... then it should read 5200 for a motor turning 2600 RPM.

would have to be "shaft speed" !


OK ,so take your little flying beasty chain it to the pitnit table ,place a tube over the prop
and play with the output flow ?


Or you could just take your vacuum cleaner and suck up the cat {clog it} or put it on Blow and put your hand on the end.


Listen to the motor ??
does it sound like its coasting??

yes @tinselkoala but if we just had a infrared snapshot of the whole device we could tell if a battery is embedded in the motor because it would show up as a hotter part of the image where the bats are located.if it showed the case of the motor as cooler than ambient then i would tend to rule out batteries and start to think in terms of a 2nd law violation.

We can clearly see someone Laser Taching off the rear section of the axel. Definitly reading shaft speed.

Good thing I don't have a cat, or I'd try it.

No, it doesn't sound like it's coasting exactly. It's not really blazing along either. So, not 5 watts at 1300 RPM, not 14 from punching wrong buttons, but 46 or 61 watts from good calculators based on the prop dimensions and taking the measurement of RPM as correct. I can accept that.

Can you give the link to where that can be seen? I can't stand to watch any more of those fracking ads looking for it. This is the most boring demo ever.
