An energy harvesting project

[JulesP]

Something to help the disheartened when it comes to seeing evidence of an energy gain.

Following on from comms with a developer, who contacted me describing their setup and who was trying to gather some evidence that their device was showing some indication of an energy gain, I have put together some thoughts on this important question that may be of use to others.

Sometimes the evidence of an energy gain is 'hidden' in plain sight.

The attached doc will explain and has been added to the Manual Appendices folder.

Thanks for posting this to encourage others. It is well written and explains things I've struggled to explain to others.

Thanks Gary,

It is also worth remembering that in the original story of the SG device, built by Shawnee Baughman, it describes not how the device ran some external load, but that the batteries were not running down as expected, based on what the device was consuming, but lasted much longer - which annoyed her science teachers!

In other words, the energy drain in running the device was being offset to a significant degree by the effect of the pulses on the battery.

Just repeating this observation should be seen as a substantial success.

Hi Julian,

Thanks for your elaboration/post #60.
Once I get to the point that my setup is build, and having some experience under my belt, will for sure consider doing some of the verifications regarding my questions (e.g. the diodes).
I’ll be on a holiday for a while, but will have a look now an then here on the forum for updates. Looking forward to read through your article of post #61.
Most of the parts/components from the list I have ordered, should all trickle in in the upcoming weeks.
Regards,
Rodolphe

I should have some results to post in 2-3 weeks but from initial tests the device behaviour with swapping is very different from when doing single cycle CoP tests however accurate those may be.

This may change the way you want to proceed with your build. I will likely probably be looking to find ways to improve things performance.

A relatively short update on what has been happening with the load testing. There is both good and not so good news, but it’s early days in the process.

On the good side there is clear evidence of energy gain, which is my primary objective scientifically speaking, but so far the predicted power outputs have not been observed and I would like a much clearer result.

There are various possibilities why this might be so. One of the main contenders is that in the CoP tests only one discharge/charge cycle is undertaken with time between for the energy and charge to be chemically assimilated. In live load tests, at the end of a charging phase, the battery goes straight into a supply phase and so there is little or no time to ‘process’ the incoming energy.

The graph below is an example of where the net voltage change after a series of swaps leads the battery voltage to be the same as at the start when compared to a control run (green plot) where the monitored battery received no pulses but only acted as a supply for the other battery to be pulse charged. This is only a short test run but it shows the principle, as mentioned in my piece entitled ‘Am I seeing an energy gain?’ where the receiving battery is not losing voltage as fast as it should give the energy it is supplying to the system.



However, I believe the system is capable of far more and this is sought to demonstrate the above point far more clearly and conclusively and I am exploring a range of developments to address that. These include revisiting the cap dump circuit to see how live load tests work with it. It had been sidelined given that the CoP results were poor but, given the apparent lack of correlation between CoP and actual power output, it may be better in practice than in theory.

I will also be investigating how changing the discharge voltage from the cap dump unit affects performance including using smaller higher voltage storage capacitors for a higher rate of delivery but at a lower charge. In addition, I will be experimenting with pulse combining whereby the high current pulses from the cap dump unit are temporarily accompanied by a burst of HV spikes to accelerate the charge delivered. This is something that Peter Lindemann commented that he and Bedini had found useful and this is illustrated in the graphic below. A prototype switching circuit has been constructed to use with the cap dump unit to test this idea in the coming month or so.








Lastly, I will be seeing how changing the three output diodes (IN5408s) for one Silicon Carbide C3D06065A diode affects the pulses to remove any possibility of ‘pulse throttling’.

Plenty to be getting on with as winter merges into spring.

Hi Julian,

In the videos of John Bedini*, he mentions that if you work in pure radiant mode (=just HV pulses), you cannot swap out the output battery for the input battery when the charge cycle is done. If you do so, he mentions that the batteries will both run down. (this in contrast to using a cap dump system). However, the first image of your post #66 shows it IS possible. But as you stated it does not yield the CoP that you calculated with your previous test setup.

Taking into account what JB said, you could try the following: Use the setup that you used for the initial CoP calculations (so no swapping, DC power supply as input), and run a resistive load directly off the output battery while it is being charged, while monitoring the power used by the resistive load. Or, alternatively, instead of putting 1 batty at the output, put two in parallel. It’d be interesting to see if the CoP of any of the above two mentioned setups come closer to your original calculated CoP values.

Hi Rodolphe,

That’s interesting and I wonder if it’s because of the reason I suggested, that there isn’t time to process the radiant energy in electrochemical terms. Does JB give any further details as to why?

What I have shown is marginal so I’m hoping the use of the cap dump system will give much clearer results.

Other researchers are using the mechanical output of the primary load (rotary switching system) to drive a normal type of generator to produce regular ’hot’ electricity. Presumably they use the HV pulses to run a cap dump system as well to feed back to the batteries.

Another major issue is around the impedance of the system and the convenience of using SLA batteries, Lead Acid or Lithium, is more than offset by their high internal resistance. A typical 7Ah battery will be around 200-300mOhms compared to a fluid filed car type battery of 20-30mOhms. One is far more likely to see radiant effects with the latter which I will soon be examining.

Yes, in due course I will be trying to run a load off the battery being charged using both HV and cap dump pulses.

Lots of variations to try, which is far better than hitting a dead end!

Hi Julian,

Just got back from holiday. Will have another look at the DVD soon and let you know if some more of his comments/details about the HV pulses.
Most of the components came in, still waiting for the the volt/ampere displays, which are holding me back of ordering/finalizing design of the base plate. Picture below is work in progress. Main thing I'm battling at the moment is time .

Best regards,
Rodolphe
