Spinner and Omega_O,
I probably should have never brought up things I have done in the past.  It is true that I made a magnet wheel ten or twelve years ago.  Sorry you don't believe in me but I did it.  I have no reason to make up stories on this website. 

OK, I'd like to believe you... But you have to understand that the world is literally filled with similar claims, and somehow not even one of them came into fruition... You must understand that a skepticism is a natural response (nothing personal)...

Making the new video, I have truly been having problems and it takes time to solve problems when changes are made.  It seems like so many people doubt my credibility because things I do are hard to believe and are against convention beliefs.  But everything I say is the truth and I'm getting tired of having to give explanations to people on this website.  As I explained in earlier comments, there are a lot more people working on this than me.  I was warned not to go on this type of website because of skeptics and nonbelievers.  Most of the people pick on anything they can find...

Hold on... I (or most of us) can understand that you may have problems with improved replication... No problems with that. Your posts made so far are showing that you're (probably) a sincere pearson, and you are convinced that you "have the real thing"... Nothing wrong with that, too...

It's good that you have a professional help (from the people you can trust). Don't you worry about the conventional science/beliefs - if you have what you think you have, I'm sure that even the "blind orthodox science" will realise that sooner than you may expect...
Btw, if you decided to show your work in the public (like on this OU site), you should expect a mixed emotions replies... If you strongly believe that you "have it", than not even one of the "negative" posts should disturb your work...

I still would like to thank people for all the good comments but I'm really thinking of cancelling my membership on this website.  The machine will be getting documented as soon as possible.  Likewise, the new video will be out as soon as possible.  But I'm finished for now on this website.  I will not be back to reply on any comments until the documentation is complete and the video is finished.  Good luck all.
James

Why would you cancel your membership here? I can understand that you are very busy, or even that you may be angry because of some skeptics comments (like mine)...
But you have promissed that you will show us a new video of your device, and that you'll provide more data (complete documentation?)... Yes or no?

Please, don't make the same mistake as hundreds of people made before you....

Cheers!

Don't overlook the flywheel in that vid.
that's why he can have time to switch the plug.
Bigger flywheel = more time to switch the plug and smoother operation but you pay for that with more energy initially to get the system up and running.

The choppiness seems to coincide with each paddle wheel passing the water stream... there must be a smoother setup for that.

Had some deep meditation about pelton turbines ;-))))

The ones I know are of the extreme heavy style with huge mass huge inertia _AND_ they are almost directly coupled to _heavy_ generators.
This is the reason why any oscillation of torque is absolutely wasted energy. It sucks the power back from the inertia of the system _wasted_.

What we have here is a super-lightweigth (compared to the other elements, involved kinetic energy) wheel with almost no inertia tribute to the system.
Because it is coupled with a belt to the generator - which is capable of storing lots of inertia(the gen) - if I see the pretty long acceleration phase - and the long rundown time.
The relatively elastic belt can store / release the input energy in a way that the resulting efficiency is still high.

JD meant that the pulley drive is some feature which had a high tribute to the performance of the system.
This is the reason why I still claim - that under this circumstances - even such "infficient" "looking" stuff can gain high efficiency. (as long as the involved components match)

If you look at the internas of the pump  and notice the almost _ instantly on_ behaviour (on the testrun) - as well as the same on unplugging the pump (at the end of the video) there is pretty no inertia with the pump.
The powerconsumption/efficiency of the pump depends on the rpm/vs flow. This relation is negative as you see in the datasheet. rpm constant, high flow, high load, rpm constant, low flow (height to lift), low power consumption.

If the voltage of the generator would drop slightly, the rpms of the pump would go down immediatly (no inertia) - the rpm/vs flow would change
in the direction of more efficiency, higher load (from pump view) and would finally give more ouput. In this case the pump has some effect we would
call negative resistance in EE. BTW, more energy is sucked from the generator witch is immediatly feed by the belt and the pulley with some energy back.
In the video the speed locks quite stable for some time - but if the efficiency is higher than you expect - this system can have a very long rundown  time.
rgds.

Hey, Fritz! Interesting thoughts, for sure! Hmm, maybe..?...

Although I don't think it is the case. I think there's no intermittent or turbulence actions, no resonance or elastic belt oscillations, no "negative resistance" parallels... And no "FE". ..
Sorry!
Of course, this is just IMHO... I'd like to be proved wrong, believe me!

Btw, do we have any replications yet? The setup is rather simple, made of common parts. It shouldn't be hard to do ...?

Cheers!

Maybe you didn?t get the point....

1)
I meant that a pelton only needs to be a pelton
if its heavy like a pelton, has lots of inertia and/or
is directly coupled to a generator with lots of inertia.

2)
Because of 1) - a lightweight paddle wheel which is
coupled via a lossless spring system too a fat inertia
can be high efficient - because the (potential) losses
due to torque/speed oscillations(because of less paddles than in pelton scenario)
are backed up in the spring and released to the generator.
(ok its a belt here - not a spring)
Because of the dominating kinetic energy of the water, the
oscillation of the paddlewheel(inertia) is quite low, rest is stored
in the spring and released.

3)
This pump type works with constant rpm - with constant
voltage. If the voltage changes - rpm changes.
The current it sucks depends on the relation rpm vs. flow.
For high flow == high current. lo flow - low current.
If you have medium flow x with nominal rpm, nominal voltage
and medium pump current - and reduce nominal voltage to V1,
you have lower rpm R1, but improved rpm vs. flow. This means
that current I1 will be reduced to V1 because of ohms law,
- but because of the improved
rpm vs. flow - the pump has another setpoint - means the current drop
will be less or in an extreme case negative.
This would look like the resistance of the pump goes down with
decreasing voltage (which is in fact no negative resistance - just used
the wrong words) but is caused
due to the shifted operating point of the pump.

4.)Because of all those issues and high inertia involved - I expect
a non OU with very long rundown time.

So from my point of view - there is no glimpse of strange or hypothetic
operation. Just very matched components.
(The behaviour of the pump is well documented by the datasheet,
and the stuff with the paddlewheel sounds pretty logical).

anyway.

Has anyone here looked at the capacitor setup. What I see is two dual electrolytic capacitors. What I see is one wire coming out of the generator going to the + side of the first capacitor and the minus side of the first cap going to the minus of the second capacitor and exiting from the + side of the second cap into the wire that goes to the plug receptacle. The other wire from the generator to the plug receptacle, has the same hookup??? It used to be a common practice to use electrolytic capacitors in a AC circuit with this hookup. I admit I let my imagination run a bit but you really can't see the hookup on the lower wire and it does look like these are dual electrolytic so I am making some assumptions. This is how hendershot used his capacitors in a AC circuit. I would like some input from anyone here with their thoughts on this. Also if these are motor run capacitors why are they in series and has anyone seen this done before. Normally capacitors are used in a generator/alternator to regulate voltage. This is not the case here.
If this is hooked up the way I think, does it tune the generator? Or the motor? Or both?
thanks
