David Bowling's Continuous Charging Device

[Hoppy]

Hoppy,
There is definitely a way to prove beyond a shadow of a doubt that this thing puts out way more energy than is contained in the primary batteries.

David,

If you are confident about this, then you need to detail exactly how you intend to work out how many ampere hours have been extracted from your primary batteries, given that the mechanical loading on the motor(s) and any applied electrical loading (such as an inverter) on the batteries will be variable over the duration of the run. The rate and level of current draw from your batteries will affect the run time (ref: virtual capacity - Peukerts Law). Also, How do you intend to properly measure the current drawn by the motor? Think in terms of using a power analyser which will give you total watt/hours, which can then be converted to Amp hours by using the average secondary battery voltage measured over the duration of the test. See this link for examples of power analysers: http://www.youtube.com/watch?v=4RkldBzc-Vs

With an instrument of this type, you will also be able to determine the amount of energy in w/hrs delivered to the primary batteries during the charging process. This energy of course needs to be taken into account when working out the overall efficiency of the system.

I purchased a power analyzer. Should be here in a couple days, but this pushes things off until next Wednesday. That gives me some more time anyway. I'm not sure if it will work since the motor is wired between the positives of two batteries, but I can still use it to measure the DC output of the generator in amps and volts. I can measure the output of the inverter through the kilowatt meter. To measure what the motor uses I can measure the amps, volts and time it has been running. Since it will run at a constant speed, that should be accurate enough for this test. Because I think you will be surprised by how long this setup will run.

Good move. I mentioned overall system efficiency. You need to have some benchmarks as to when you re-charge and measure the input energy to your your primary batteries and a consistent re-charge period between test cycles. This is where the SG level may be a better benchmark than voltage levels, assuming you can measure this accurately enough. The system COP will tell you how close to unity your system is running. This is not a straightforward procedure and as I mentioned earlier, it may be difficult to determine if any free energy is entering the system, especially as I predict the COP will be nowhere near as high as you are expecting.

Please document your test procedure and your measurements for each test cycle, preferably in spreadsheet format, so that all interested parties can use these measurements as a basis for conducting their own tests for comparative purposes. This should encourage more people to come on board to build their own 3BGS systems.

Hoppy,
I am going to run the Modified 3BGS circuit. There is no need to stop it and rest the batteries. It is a stable circuit. The buffer battery stays at about 12.2 volts while drawing energy out of it to run the inverter. The two dead batteries hold their voltage, although sometimes transducer 2 climbs in voltage (which we DON'T want.) And the primaries hold level. The longest run anyone has done with this circuit is 10 hours. I believe I can run it for a really long time, so measuring the SG of all the batteries once at the beginning and once at the end is all that is needed. No stopping, no recharging of anything. If transducer 2 gains too much charge, I will simply stop, discharge it, and start again from where I left off. I am going to run it until it won't run anymore or several days go buy of recorded continuous loads that far exceed what is possible from two batteries, and then we will measure the SG of all the batteries again and see where we are. I know you don't have any faith, but I do. I have been working with this for five years and I know what I have seen. Too many others have seen the same thing.
