well then do not bring forth said prophets if no one is willing to follow/defend them.
I have many more of these ideas regarding topics.

I realize I am loud. But this message is important.

I am sure you all can translate these ramblings. if not I am open for dialogue

Thw waterwheel in this video looks like yours.

https://www.youtube.com/watch?v=lCNcwsglZP8

I haven't posted in a while but checked in today. Lots of people have been taking clips of my videos and are using them in their videos without my knowledge. 

With regards to my waterwheel, it's still running and going on almost 6 years now. I haven't changed over to the chain drive yet and may not since I would have to go to extreme measures to keep the water off of it. I may just bite the bullet and order a timing belt and sprockets/sheaves to match.

The wood bearings are still working, but have worn quite a bit. A while back I ordered new roller bearings to put in my original pillow blocks as well as a new type of seal that should work better to prevent water ingress. I would still put a splash shield over the entire assembly to keep water off the bearings. The roller bearings would be more efficient than the wood ones as there would be less rolling resistance.

As  far as adding more blade area, I'll get to that at some point. Maybe when/if I retire in a couple years.

I'll be sure to update the forum if I make any changes.

Thank you Bruce,

understood gang.

I am still open to some more of this mental support like Bruce et al. have been displaying,

Look I am a small fish playing with big concepts. It is easy enough to just accept defeat.

Brandnewb, do not tease us lol

No really Brother. I need to know what you actually meant to convey!!

hahsah brother. You know I am not a tease. I often get right into business

anyway gang.

Please review this better representation of the magnet configuration.
I am moving forward yet there is still time to raise objections or improvements to the way I represent my setup/

The setup is what it is and I am past the point of no return now to change that unless I find something wild that changes my mind.



I will make sure to measure all of the positions I think are of interest in terms of magnetic field to start with.

Is everyone still in the believe this is going to suck in terms of wattage capabilities?

I for one never did.

I just cant see yet why it would not blow things out of the water. But I am always open to be wrong.

Brandnewb, do not tease us lol

We recently fixed the image upload function, this happed to all users not just you.

I am happy to report progress.

so after a considerable amount of extra experiments I found that there might be a good reason to use smaller diam wires after all.

You see that I now hold the believe that while using litz wired coils one can have more wires exposed to the field where it matters as opposed to a single larger diam wire.
And since we are talking about AC here rather than the DC tests I run for establishing a field strength there is soo much less heat build up as the electrons go back and forth thus constantly not going at full speed. (this is just what I think there is going on. totally not based on actual science!!)

Please allow me to explain.

Does one remember when I asked to hold ones buttocks most recently?

Well that was a single wired 35-70-35 coil in but 3mm.

When spun over close to the magnets it spewed out an insane amount of vAC. More insane than I have ever seen in similar conditions with only the coil as parameter. It was for sure the most impressive voltage generation I have ever seen in my line of testing yet. In that context of course. Sure I have seen higher values but that was because the coils were more potent.



Now please remember how sad I was when I was unable to demonstrate a beneficial voltage generation ability when a similar coil was backed up by iron powder.
Yeah that pretty much stopped me dead in my believe that I can think of new ways of demonstrating my hypotheses. I for one for now still do not know any other experiment I can try.

Well 2 things turned out in favor of good old iron powder in the long run. Hahah what did you expect gang? That I would lets things go that fast?

It turns out that having the coil legs of this said coil being backed by iron powder legs then the field it produces at 32 vDC is around 13 mT rather than the 10mT when not backed.
Ok Ok I'll be honest. I am not even sure I actually correlate those two findings. So just let us put that in the freezer for now.

And then of course the second thing which was actually not a new thing but the insane heat dissipation enhancement it all brings.

So I am going to take shortcuts now as I can't create charts that will satisfy everyone.

So I will make the next few posts on what charts I am going to make and then allow for suggestions on how to fine tune them before I actually start going deep and start endless measurements.

Also I have some other good news. Remember when I said that 3mm was minimum? (the narrower one can make a coil the more field it will produce where it matters (close to the magnets)) Hahahah turns out though that that was not even the minimum thickness.

Nah, this will be my baseline coil after some consideration. I have one thing holding me back though. Perhaps a 35-70-70-35 configuration would be better. Please share your thoughts.




The niche part about this test coil is is that it is but 10mm thick while boasting a litz wire of 5 x 0.4 mm.
One thing I do know already is that but 1 wire out of that lists wire will produce around 7 mT at 32 vDC. But my lab equipment is not up to the job when exposed to 5 times this simple coil. It just starts being unable to just blast on.
Anyway with my farmers logic I get to around 35 mT.

wait what? 35 mT holy smokes!! if that is true.

Yeah my thoughts exactly. I hate it when a plan does not come together as I clearly did not buy the correct lab equipment to be able to run scientific analysis at this scale.

More to follow on how I plan to document things before we actually go and do it.

{1}this is the magnet configuration

Thanks guys, it does indeed work!

BMS is fun to watch, sort of like paint drying but yet captivating.

I use a 30v smart charger to balance the one out stack.

     


   

Bravo, fellas.  Now is the time to take snapshots of the data.

 Ya Flavio is right

"Host finally woke up and listened, thanks to JW who kept insisting and to me that I kept telling everybody I knew what was wrong...

Haaaa!

 

Host finally woke up and listened, thanks to JW who kept insisting and to me that I kept telling everybody I knew what was wrong...
Well anyway,

this is an old Fieldlines logo draft to celebrate.
I would like to say sorry about it once again but it has been beyond our control for quite a while and we had to ask for third party to wake up and do what they were being told, which took some time.

Emails are being worked on, urgently.

I wish you could post pictures of your setup. It's always neat to see what other off gridders have come up with for solutions.

I agree, it is nice to see what others have done, a great way to find ways to incorporate and make things work better. My houses has a 48V solar system. My well pump shed has its own 12V solar system as the pump is a simple pump with a 12v pump and now I am installing a 12V solar system in my gen shed and sea can. I will only need to fire up the Yamaha 3000watt generator to charge house solar panels in the winter on the short when there isn't enough daylight, but that may be resolved when I add a couple more panels or fire up the 11,500 watt generator to weld.

Right now and through the summer into fall, it takes about 2 hours for sun to top up the batteries from night usage and 3-4 hours if it is overcast. If I can figure out why it won't let me upload picture and get that resolved, I will upload pics.

Well from 5 days of working this 100/50 has put out 26Kwh and the over night low voltage has gone from 22.9/ 23 it has risen to 24.8 and higher as each day goes past. This weekend was planned to put put the 1.5Kw as my son and the rugrats were coming down has morphed into planB where my eldest daughter and her boyfriend are coming around to help out.

Now I did try to get in to reprogramming the FM60 but those soft input keys will not respond so I can just leave it alone as it's programmed for dry cell batteries and the cutoff is 28.8 volts, so basically the 1.9Kw array can do the bulk and when getting close to float the 1.5Kw array can do it's job to top off the charge. This FM60 has been going since about '07 when the MPPT failed on our first install so I really do wonder if I wake it up with 60 amps output will it wake up or say my time is done.

Topped up the battery today and after 4 litres found 10 of the cells were filled the back 2 on the negative side took close to 2 litres  and one of my old SG testers now serve as a single cell funnel. Like with my shed array by putting 6 found 1.9Kw panels on transformed the battery and I am seeing the same thing here so my claim off living off the grid for 20 years plus on a 24 volt 600AH battery stands firm and the genset is a thing of the past.

There is a good reason why I'm going to stay at 24 volts as I did wire my 4Kw motor conversion to that voltage and soon it's going to be in the air so I do think I'll be heating a heap of hot water but I do want the location to be out the back of the farm and gotta pay the council debts first before asking.

Well August is my birthday and 60 it is so that new tractor will get to dig that big hole where it take 2 concrete trucks just to make the base for this 4Kw motor conversion which won't have a tail as a disk brake will do the job.

Eh making free power hasn't been so much fun for 20 years so this is the new upgrade.

Regards Bryan

I've just started trying some of the smaller victron mppt units too.  Mostly for stuff i sell.  I hope it works for you, because i just bought 3. 

It's good to hear you are making upgrades and not spending much money.  That's my kind of project. 

I'm pretty sure i have a fm60 manual downloaded.  I can check if you like.  Send a pm and i can maybe email it of find a link where to find it. 

Google says password is 141 and the manual is on their website.  You've probably found that already, but I'm sitting killing time so what the heck.

I am not ready at all

You see the gravity torque test is not working out

It is proving really difficult to get the PMA rotating at the intended speed with the coils closed.

So for a 29 leg coil of 5x 0.4mm litz wire I got only around 22 watts. (I had to wind the coil a little less than the intended 31 legs because I never realized that when adding wires in parallel we will need more length   so I ended up short thus the 29 coil legs )

I dropped a weight of 6 kg from 2.163 m height.
and open coil it took 4.95 sec
closed coil it took 45.32 seconds but the end speed was nearly not high enough as the intended speed.

I can add weights but there will always be a ramp up time needed and also then the disk would start spinning far too fast with the coils open.
Either I do not get how to properly conduct the gravity torque test or it is just not applicable in this scenario.

I do think though that this 5x 0.4 litz wired coil is not better than a single 1mm wired coil as the area is still less.
0.4 mm diam = 0.12566 mm2 * 5 = 0.6283 mm2
1 mm diam = 0.7854 mm2

what a complete waste having bought huge spools of 0.4 and 0.71mm wires.

if anyone can think of a good use for that?

I am now looking for a reliable way to measure the amps in the coils while shorted so that i can have the motor spin at the intended speed and then calculate the wattage the coils produce.
What would be the best tool to do that an accurate amp measurement?

There are 2 hots and a neutral feeding the breaker panel box which come out the wall where I had an old generator feeding power.. Those are the wires I need to somehow connect both generators to and be able to switch ti either the 240v or 120v generator.

Any switch sold as a transfer switch could certainly be hooked on these wires and do what you are thinking.  I think your plan for the welder cord makes sense too.

Sounds like a nice setup you've got.  I have  the same inverter and so far it has been flawless.  I ask a lot of it sometimes these days too.  I run an 18" lathe off it, and just recently added a 3kw element to my gas oven to use power when we have lots.

I wish you could post pictures of your setup. It's always neat to see what other off gridders have come up with for solutions. 

If it is just a simple, "one generator or the other, but not both" situation, then a slide or rocker in the breaker panel will work fine.  Also, any manual transfer switch will work too.  One generator would be hooked on the "grid" side and the other on the generator side. 

What kind of inverter / battery charger does this feed?

As mary said, you'll only be switching the hot wires.  All the neutrals and grounds are common and will stay hooked up. 

The 120v generator will only power half the panel, and of course only send 120v out for charging. 

Hey, I am trying to hook up a 240v generator and a 120V generator to power a breaker panel box which will then send the power to the house. I want to be able to use a switch to decide which generator I am going to use. I wish I could upload a picture so I can show what I am trying to do, it would be much easier to understand.

you only need to switch hot phases, grounds are common... but make sure you use a lockout or transfer switch on the main panel to not back feed the grid!!!

I built a panel interlock that is just some sliding steel plate, that makes it impossible to turn 2 breakers on until one is turned off.  It took a bit of drawing and head scratching, but once i had it fugured, it was unbelievably simple.  It's all just breakers in a standard panel.  All i built was a sliding plate out of 1/8" steel. 

I also can't post pictures.

I can't exactly picture what you are trying to do, but maybe something like that would work. 

The Idaho Black Hawk tilt rotor clocked 38%
ANEW in Poland 41,5%
And Single Wing Energy oy 40%

So the efficiency is not at 30% for VAWTs.
