I have a few questions about using the bedini for charging batteries.
1. How efficient is it? Compared to say a solar setup.
2. Would it be better to charge a 12v car battery while running the bedini off another car battery or off of a 12v power source? For that matter what would use less electricity, a store bought charger or the bedini?
3. Could the bedini charge more than 1 12v car battery off of 1 12v battery? For instance run the bedini off of a fully charged car battery. Could it charge 1 battery thats half full to a full charge. Then charge another, then another, before the primary battery needs recharging?
The reason I ask is I plan to run my shop off of 12v. Lights and small tools, also charge power tool batteries. I would like to use the bedini at night when the solar panels are useless to help charge the main batteries back up.

hello Micah, i dont know a whole lot about the bedini to answer all your questions all i can answer is from my own experience.
1. i have never had or studied the solar setup of a charger so i am unable to give a point of view on this..however i would say the bedini would be a better decision because you can run it any time you want, unlike a solar setup you need the sun. also you can change the bedini setup to do different things, for example have it run a generator setup to generate more electricity, you could also connect other rotors on it to say operate a fan or something, anything that spins..
2. i dont have a 12volt power source other than a normal car battery..but i would say the bedini is better than a normal store bought charger from my own experience. my cars battery was dead and unable to hold a charge according to an auto parts retailer, so i decided to use my bedini to see if i could get it back to operating performance, my result was that it did go back to operating performance and it is still in my car today. which saved a lot of money because i didnt have to buy a new battery.
3. yes the bedini can charge more then 1 12volt batter from only 1 12volt battery.
if you plan on charging tuns of batteries off of one run battery i would recommend trying a battery swapping circuit, where once the run battery gets down to a certain level it swaps and turns into a charging battery until it is back up to operating levels. theDaftman has an amazing circuit layout and video of this...this in theory should keep the device running until the life of the battery..i for one have never tried this, yet.

Cass: is dead on with this.
Micah:
I have had allot of experience with solar and I can tell you there is a whole lot more to it then buying a cell and throwing it on the roof and expect it to charge up anything. remember the figures on the box or website are best case numbers and you must cut this output figure into almost more then half for a reasonable figure and there is the weather and the latitude you live at IE how close you are to the sun. More to the point is if they get dirty there is a loss there and in the winter verses the summer too. that is all the easy part too, most solar cells are configured for a very Sunny place say California or Florida now if you live where I do in Utah I will only get 1/3rd the power that the cell says I should get because of the angle to the sun and the cloud cover and then there is the smog too.
The size I would need to keep a battery charged up would be 36" x 36" so 3 feet by 3 feet. just for one battery and at that it would take 3 days of no clouds at full sun. So to do it in one day would take a panel that is 10 feet by 10 feet, in the summer time.
I know what the box says and what the sites say but real life for a solar system is vastly different then what they test at in the lab.
Now there is the life of the panel most will have a 20% loss in the first year of operation and it goes up each year till they fail all together in about 5 years.
I'm not bashing solar but just letting you know the facts. Good for an RV to keep things charged up but to run a shop you would need more then the space of your entire roof to really make a go of it and the cost would be in the thousands for the system.
As for the motors we are designing and discussing the best example to keep in mind is like a big gear turning a little one. the big gear turns slow and is easy to move and the little gear spins allot faster. what I mean is it takes less power to make motion using these motors thus they can be connected to a vast variate of generation systems that produce more power then it takes to run the motor.
So building a motor like ours here are the most efficient way to make use of the input power for a gain in the output power you can get.
I think I have explained the differences but if I missed the mark please let me know.

BATTERY TEST FOR THE BEDINI MOTOR GENERATOR
(Unidentified internet source)
DATE : OCTOBER 13, 2000
BATTERY TEST SEQUENCE:
One lead acid gel-cell (12 volts, 450 milliamps) is being utilized as the primary source fully charged at 12.5 volts
Three (3) lead acid gel-cell batteries (12 volt, 450 milliamps) strapped in parallel are being used as the charge destination. The batteries are discharged to 10 volts for the test purposes.
Test #1 starts at 10:45 AM utilizing primary battery fully charged at 12.5 volts charging three (3) destination batteries paralleled. The destination batteries reach a charge capacity of 14 volts at 11:20 AM.
The destination batteries are then discharged to 10 volts under working load to prepare for Test #2.
Test #2 starts at 11:25 AM utilizing primary battery measured at 11.5 volts. Charging three (3) destination batteries paralleled. The destination batteries reach a charge capacity of 14 volts at 12:50 PM.
The destination batteries are then discharged to 10 volts under working load to prepare for Test #3.
Test #3 starts at 1:00 PM utilizing primary battery measured at 10.5 volts. Charging three (3) destination batteries paralleled. The destination batteries reach a charge capacity of 14 volts at 1:40 PM.
The destination batteries are then discharged to 10 volts under working load to prepare for Test #4.
Test #4 starts at 2:05 PM utilizing primary battery measured at 9.5 volts. Charging three (3) destination batteries paralleled. The destination batteries reach a charge capacity of 13 volts at 2:40 PM. The primary battery is now discharged to 9 volts under working load and unable to further run the
Bedini motor generator.
TOTAL BATTERIES CHARGED:
12 lead acid gel-cell batteries (12 volts, 450 milliamps each). This ratio is a 12 to 1 charging factor. The motor operation (work) being performed as this was done is not included as an additional factor in this test.
www.peswiki.com
-That is what you are hoping to do, correct?
I have also seen a Lidmotor youtube video, where he runs
a light and charges a battery (or 2 sets) off a small
solar panel outputting ~12V and 30 milliamps! Lots of
useful work for under 400 milliwatts!!!

Yes this is very true A solar panel could be used to charge the run battery for the pulse motor to run to produce rotation for a generator for a higher output of electricity to charge the main load battery's.
However a simpler way is to use 3 coils 2 motor coils that trigger and charge the run battery and a battery swapping circuit and the 3rd coil for the charging of the load battery (bemf can be collected on all 3 to charge the load battery)Adding more slave coils will produce more power for charging the load battery's as well.
I guess the best way to think about this is like 2 closed loops.
The first::: from the run battery through the circuit to the coil back to the run battery and so on till the voltage drops below 11 volts then the relay trips to the charge battery and this is charged to 12 volts then the run battery becomes the charge battery closing the loop again. (bemf auto charges the opposite the load battery) This cycles till the battery can no longer charge and discharge. IE power failure.
The second is the load battery:::: this is charged by a slave coil dedicated to the load (BEMF can be collected as well) this charging coil has no load to the running of the motor (loop one does this) so all power developed by the slave coils can charge the system. ( you can use as many slave coils as you want to. (this is until you corrupt the magnetic fields and stop your motor)
This is why these motors are so attractive to this type of work since it takes so little power input to gain a large output.
Well I hope this helps and I am on the right page with you on this.

Hi all this is one for the Daftman (or anyone else who has tried this type of motor), after watching TheDaftman window type pulse motor video, I was wondering if when the coils were wound the correct way it still had the same ( if not better) charging potential?
thanks

Dude MATT,,,,, Way out of line, here this is not for aggression, CW was doing his job as a MOD. He has a responsibility to all of us here on the forum over 400 others that all need help and wait for replays and provide information.
He is totally right we here post to topics about specific items that pertain to the start topic, if the information does not pertain to that topic then you should make your own topic. As we all do here.
Bashing some one is not tolerated here and is looked down upon by us all. Leave the attitude at home not in this forum. We as a whole do not want to see this.
We are here for the common good for all the world no mater race creed or color none of that matters here and the aggression has no place here at all.
As we had replayed the best way is through photos or video. the reason is pure reflective vision into your problem. I understand you don't have a camera, Pawn shops sell them for next to nothing. also Ebay, or a cheep disposable scanned into your computer and uploaded to the site.
Rest assured CW is "NO CON" and that is offensive to the hundreds of people he has helped with great care.
Please be respectful of us all here.
As soon as you can send more data on your problem I will be happy to take a look and see what can be done.

Micah: I have used a magnifying concept to get as much bang out of the sun as you can, heres how to do it and it is not easy but does work very well.
you will need a tracking set up for rotating toward the sun with motors and circuit with light censers set for the angle and best light ratings.
next you will need a parabolic mirror, the size is relative to the size of your solar panel, next find its reflective indexing point this is the focal point for all the light coming from the reflector, (yes there is some math involved here and a long and complected formula) now set direct above this is your solar panel facing the reflector so its back is to the sun. the concentrated light from the reflector will be focused on the solar panel like a Lazar and will increase the output up to 500% from just a flat facing panel.
Now what parts you will need:
A rotating carriage and motors with circuit tracking system
Parabolic mirror
Brackets for solar panel fit
Solar panel ( round shape ) may need to be custom. I have a few made if you want a photo.
Charging circuit
battery bank
and your DC to AC converter for home use at least 3000 watts
If you want a simple drawing of this please let me know, but I will tell you it is an expense to have all that stuff made.

| I think your right vesperhbt that would be very expensive! If I was setting this up to run my house maybe, but its for my shed. I think im going to go ahead with this project. Im going to post a new thread on how to make the bedini as efficent as possible. If there is already a thread like that could some one post it. I looked and didnt see one. |
