I have seen these type of machines before but not to this level. (It was a long time ago when this guy in Korea was talking about endless energy...) Of course efficiency of materials and the technology has changed considerably since 1996 but this is still pretty neat.

I find these videos very interesting.....His final point was....that these types of machines can be supplemented with a solar panel and THAT will turn a generator to make electricity or pump water, ect.redbenjoe said:yikes--i just invested the entire 30 minutes to carefully study these 2 videos -
and i now feel like a moron --
rednecks will ask
1. how big is your feret ?
2. can it beat a yuppie porsche turdo ?
3. is perpetual motion good with beer ?
Still very interesting.
Of course I could get the same from putting the wife on a stationary bike!
....and the other redneck answers
1. About the size of a cat
2. Yes
2. Yes, but only Budweiser
Technology is nowhere yet near which one might think this video is suggesting. Firstly, you need to consider that the amount of charge that the ultracap (at 350F) stores is probably about as much energy (work) as you might get out of 1 AA battery. And those ultracaps are expensive for the amount of usable energy. Capacitors and standard batteries are indeed different technologies but both do store energy. The advantage of the Cap over a conventional cell is that caps have much higher charge/discharge cycles than conventional batteries but the biggest benefit is the ability of a capacitor to charge up ultra quick and discharge (blow it's load) almost instantanously. Conventional batteries have high (relatively) internal resistance that throttles the release of the power. It can power boomboxes fine. But if you need an instant high surge of massive power, it can't do it due to this resistance. Therefore, for applications that requires a huge burst of energy, capacitors are better suited.
As for his motor, the size is actually quite large. 1' x 1'. Compare that to a modern car starter motor which at a small fraction of the size, develops enough torque to turn over a diesel bus engine, or at least a high compression race car motor. For all the size of that motor, it doesn't even develop enough torque to start itself. It needs a push start. So my guess is that the amount of hp it generates is quite small and incapable fo any practical application as yet. Also, he installed a 25 watt light bulb and the generator noticeably loaded up (any more and I bet it will stall). During this time, the bulb was pulsating which suggests it was getting less than 1/2 it's normal power. At normal household current of 60hz/sec, our eyes can not visibly detect flicker. On his bulb, it was not even flickering... it was pulsating. I am going to guess that the bulb is observing less than 10w of power. Small honda generators will produce 600w of power pretty easily, right? Larger portable generators produce 5k, 10k, or more of usable power.
Then the title itself suggests perpetual motion with the generator powering the motor perpetually. However, he said himself that eventually, it will run down and stop. Here's what I have to say about that. The motor is so weak that you have to push start it to get it doing. I bet a boombox cassette motor might provide the same or similar type of power. Connect a cassette motor to 10 D cells and I bet it will run for many many days before stopping. In fact, I would not be suprised if that same motor was running a week or two afterwards with D cells. So in other words, by replacing those ultracaps with D size batteries, I could see it running 10 or 20 times longer than the caps before it runs down. There are a LOT OF CAPS on top of that motor. And if the generator could be recalibrated to recharge batteries instead of caps, then I think it will still work similar.
However, I do believe that just using batteries without the load of the generator will result in more efficient operation. I say this because of the difficulty (or impossibility) of anything better than unity gain. In other words, getting out more than you put in. Obviously, there are going to be efficiency losses due to friction and what not. With unity gain, you can get 100% out of 100% in. Subtract losses and you will get something less than 100% return on your input investment. The fact that his generator/motor assembly can not run forever and eventually runs down already indicates that he can not obtain unity gain. Well, then if that is the case, they why bother with that weak generator portion at all?
Admittedly I did not watch all from beginning to end. At some point, I started to get bored. So perhaps I'm missing something but this is my take. As usual, I'm probably wrong.

My watch has been running for 5 years, non stop and it has what looks like a normal watch battery but it is in fact, a panasonic mt-920 capacitor, shaped and looks just like a normal battery. You know the old automatic watches that winds the watch with arm motion? Well this one has similar mechanism but instead of winding, it recharges the cap. Technology seems to be fine for this application because it has been working for a very long time. I wouldn't say the cap never needs to be changed but it does seem to last much longer than with the cap as opposed to a battery. But watches consume very little power. Most watches will run for 2 years with the amount of power stored in a button sized battery. In other words, very very little.redbenjoe said:
You can create a cap powered system for a boombox. But like I said in previous post -- check out the pricing of ultra or super caps. Very very expensive. And the amount of work energy stored by the cap is relatively small compared to the amount of energy that is stored by conventional batteries. You can see this phenomenon in action with certain boomboxes which seems to continue to run for a second or two after unplugging. That is the residual energy released by the caps. A second or two is not a long time which is why you need ultra or super caps. Also, caps can be dangerous. Due to the low internal resistance of capacitors, they can release virtually all of the energy instantaneously. This can lead to quite a shock, even at low voltages that normally is not dangerous. If you connect 10 D cells together and touch the ends with your fingers, you "might" feel a tingle. I say "might." If you touch to your tongue, you most definitely will feel a tingle. However, with a ultracap charged up to 12V, I'd say you probably do not want to touch the terminals. Low, even 2v can release enough energy to melt a wire short circuited across the cap terminals. On the following videos, you will notice how they are treating these with the utmost of care. The greatest value to these that I can see is the ability to release a huge amount of energy in a short amount of time -- providing the power to start a car engine?
Here's a couple videos that better demonstrates the ultra high discharge rates of super capacitors:
Don't see our old youtube feature button so this is the best I can do:
https://www.youtube.com/watch?v=BVQ7_Iy_h0E
https://www.youtube.com/watch?v=EoWMF3VkI6U
The second video does a much better job of explaining why the capacitor, which only stores so little power compared to conventional batteries can do so much.
See, I knew this thread was for Norm!
I like the second video..."Wow, that Beaver really took a pounding".
(see 1:20)
Ahhh, science for us idiots!

I just had a flashback...(no pun intended) of when I used to work for American Tower Corp. We built wireless sites across the country and sourced tower lighting from Flash Technologies (SPX). The key to the system was a bank of capacitors that would rapid charge and discharge for the flash cycles. Needless to say if you touched the wrong part of the board it would knock you on your ass. It has been a while since I have dealt with that kind of technology but to put out the light power to outshine the sun at 1500 feet meant for a pretty hot cap setup.

Well for the price it cost to build this and only good for recharging batteries it seems pretty useless for general public 
That thing costs thousands if not tens of thousands of dollars to make. Well, maybe the guy says no, the cost of materials was only........ OK, so how about the cost of or access to all the specialized tooling equipment it would take to build it and the time investment involved? And it can only recharge small stuff. Remember, the 25 watt light bulb loaded up the generator and it wasn't even able to source the full 25 watts. Then in order to run, it needs to either be powered by other batteries (see the array of 7x 9-volt batteries) to run it. Otherwise, it can run off the bank of capacitors but only after they have been charged up and only until they drain down. The guy said in his demonstration that he already charged them up. Well, how long did that take and how many 9-volt batteries did that take. Seems pretty pointless to use batteries to charge up other batteries. Wait. The way I see it:
batteries --> runs motor --> runs generator --> charges up batteries. Resulting battery capacity (of cells being charge) = battery source capacity (of batteries used to create the charge) MINUS efficency losses. WTF?? WTH?? Why For????
Demonstration Coolness: A+
Practical application: Fail.

Actually Freddie, the technology you speak of has been in existence for decades. I'm talking about the flash units used on cameras since the flash bulb. Basically, a capacitor charges up (not even a supercap since it was before that time) and it discharges into a step up transformer to generate the momentary xenon flash. Those days, you can even hear the flash charge up (it whines). Of course being older capacitors, they take much longer to charge up than supercaps. Most of you that have worked on PC boards with large caps have probably already seen the discharge capacity of regular caps at work. If you work around a charged cap and accidentally shorted the cap terminal, you will likely see a fat spark and a torched, maybe cratered area of the screwdriver or plier that did the shorting.oldskool69 said:I just had a flashback...(no pun intended) of when I used to work for American Tower Corp.
