David Bowling's Continuous Charging Device

[lon92]

Hi y'all!!
It's me again... 

I just done my experiment... 
The result is exactly same as Groundloop... 

I have the same question here...

How to kill the battery!! 



Thanks!!
Have a good day...

@ lon92

If you don't have access to a lawyer or a politician to drain the life out of your battery as Cap-Z-ro mentioned (can't stop chuckling over that one)  please refer to Reply #146 where David mentions  "If you flip the switch and yours starts up, you know that you do NOT have a dead battery in the #3 position, so go find a DEAD one."

There are several posts where David talks about the dead battery and it seems critical that it needs to be completely dead so I think that if the dead battery is able to sustain any kind of voltage it's not dead enough.

The battery that I'm using has been dead for several years and doesn't hold a charge for long but even though the motor started up after several minutes after the switch was turned on Battery 1 & 2 were depleting and not recharging in my experiments so I'm still waiting for the proper motor to arrive. 

I'm afraid that if this does work it requires key components as David mentioned in Reply #45 where he says "Going back to the very first experiment I did with my original motor, two batteries and my original dead battery and start over"

Thanks Goat for your reply... 


I just retry the experiment  with a dead battery...
Just like you, the battery died about 3 years ago... 

At earlier test, the motor not rotate even an inch...

After about 5 hours, the motor start to spin slowly... Its alive!! 

The motor run at the same speed for a day until the batt. 1 and batt. 2 exhausted... 

Odd...

@All,

I can't get hold of the CIM motor so I tried something different. First I "tuned" my
motor impedance with a coil in series with the motor. Then I noticed that I got "big"
sparks when I connected or disconnected the motor, so I added a diode to harvest
the back emf voltage created between the motor and the coil. Now the motor slowed
down a lot and did not use so much power from the batteries. The 12 Volt 25 Watt
light bulb kept the "dead" battery at a low voltage and the light output was very bright.
(I estimate 1/2 the full light output from the bulb.) Then I just let the circuit run for
3 hours. The motor did go up and down in RPM but did not stop or start. Now comes the
"funny" part, both my charged batteries was drained a lot before I started the run. Battery
1 was just 11,7 Volt and Battery 2 was 10,6 Volt. During the run I saw that the voltage
over both batteries go down but ALSO sometimes UP. It was NOT a linear drain as expected.
I aborted the test after 3 hours because my two input batteries got slightly warm to the
touch. Next test will be with a home made coil. I will try to make a coil that I can tune
on the fly when the circuit is running.  Small steps........

Groundloop.

Is this the same motor?
Its down by the bottom of the page.
