Has anyone seen Lasersabers new motor runs on 1000uf cap

[woopy]

Bravo Conrad

And of course  thank's very much to Lasersaber for sharing as usual

nice and very good job

i am following this thread with great attention

As per Mag ,  skywatcher  , Gyula , wattsup ,. and others ,  ..., this is remaining me a lot of   very valuable thinking

good luck at all

Another way is to increase the magnets with less space N S  and with two coil drivers  ...... 
Mine does not work on caps alone but with multiple source   back emf   output to a double jt  one supplying battery back to source battery  and one to wall outlet / solar / all in parallel......   @200 mA  and 546 rpm been running 24/7  with wall power off in the evening / solar on in the morning   //// used also earth ground in the circuit bedini ssg
The important is the coil to make as generator coils   ..... best design so far is with skycollection pancake with choke in the middle....  still looking for the ultimate design
if there is a cap/battery design in the market now ,   why not a cap coil /choke rolled into one lined up in parallel to the shaft......  lots of ideas
happy experimenting

I bet the rotor can be stopped with minimal force and the motor would be incapable of driving any substantial load, such as a useful output.

Believe it or not motors usually drive loads with a shaft. The less input and output power a device has the less inherent losses are involved so efficiency is better and as well the less output such a device can produce, I see no output so the efficiency is zero.. To calculate efficiency the "useful"output needs to be considered in relation to the input.

A spinning rotor is not output unless the rotational energy is tapped for a useful and intended purpose.

This is efforts toward perpetual motion, or self running. Which has it's own merits i'll admit.

I think all who can should replicate this setup so that as many people as possible have rotors spinning from pre charged capacitors that run down over time and produce no output.
It's a very important endeavor. This reminds me of the RomeroUK hype. I don't get it what is the point. And where is the output.

Please note I have not abused anyone. I think my questions are valid. But feel free to ignore me.

The setup is like taking advantage of "dielectric absorption" of the electrolytic capacitor. The test to show it would be to remove the capacitor from the device entirely while it is running (the device would stop), as expected but that's not the point. Then measure the voltage of the capacitor, then short the capacitor terminals briefly, then measure how much voltage the capacitor regains. If a device is made to use a very small amount of energy it can be made to run from the dielectric absorption effect of the regaining of voltage. And that would have nothing to do with the motor or it's design except that it uses a minute amount of input and is not loaded. The dielectric absorption effect can be enhanced by prior charging of the capacitor and leaving it charged over time, then when shorted all the energy is not released at once and energy is released slowly over time from the capacitor, energy which was put there by charging previously.

Unless the capacitor used in the video is taken from the device and tested for dielectric absorption it can't be ruled out. I have capacitors that regain up to 10 volts typically more like 3 to 5 volts. THe effect is real and the energy is real and usable but it is energy that is previously input.

I think the dielectric absorption effect is used in one of his other video's as well possibly more, I'm not able to say since I haven't watched all his video's.

Oh and LaserSaber should feel under no obligation to do the test just because I mentioned it. If the test is done it should be done for the sake of finding out if it is a factor and no other reason.

Another way to test the cap is to have it ready to start, then just short the cap very briefly, like with the swipe or quick touch of a wire and observe the voltage regained with successive shorts, then calculate the potential energy remaining in the capacitor after each of a few shorting events and add it all together.

Well Farmhand you could at least say it's an extremely efficient motor to run off such a small power source.   Just imagine a motor like that built about 100 times bigger running off let's say a 1 Farad cap.   Seems like that might have some torque.   Just speculating here but at the least it seems like it is a design that makes extremely good use of what little power is available.    And when things get really really efficient then we may be just a hair width away from overunity 
As for dielectric absorption I don't think that's it.   I've hooked up a couple dozen big electrolytic caps that ranged for 1000 uf to 50,000 uf and 16 volt to 400 volt.   All together they lit one small 5mm LED for just a blink.   The voltage may be there but very very little current.
