Resonance and high frequency

[thaelin]

  I know this is old but can't resist. Dig a nice big hole and pour 4 foot thick walls with grounded rebar all the way around. That is what they did with the old ATT Long Lines bunkers way back when. Got to tour a site recently and it was huge. We have a 4 level parking place local that the two bottom floors are secure as well.

In meantime I have started to work on isolation method inspired by the work of "Lorrie Matchett" and Don Smith system using soft iron rod through capacitor plates.

First 50 tests looks promising but for the moment power available is quite small to allow me saying that I have something relevant. ... for small loads looks like capacitive coupling using one wire transmission doesn't load the providing circuit ... but I don't have any precision instruments to claim this 100% as there are just few mW load and may easy be lost in measurements.

Now this open up few ways for further enhancements: additional rods, additional coils on the same rod (as D Smith suggest), fine tuning for resonance and additional pickup coils(Tesla approach), changing geometry and/or materials ... few thousands ways 🤣 also I may consider using high voltage by introducing a flyback transformer after zvs for a much stronger electric field for capacitive coupling (but this may be the last resort as I am reluctant to work with high voltage for the moment).

I may start to record some videos but, only if someone is able to replicate and experiment ... otherwise it will be just a waste of my time.

So, I don't have and do not consider buying expensive tools or instruments ! My way to check the output at high frequency is measuring DC with the help of bridge rectifier. The output of little pancakes system is 160-170 Vdc, no current 😂 but loads works ... same output after capacitive coupling, much less power (for the moment), it seems that my pancake coils system can not detect any load and therefore will not deliver power ... so, I have to play a bit around to find the right approach while maintaining isolation and no power consumption from providing circuit, as main circuit including zvs driver only needs 6-8 watts.

Anyway, there is a very strange behaviour: when using main setup with rectifier for measurements when I break the circuit to put my multimeter in series with the load, power consumption goes as high as it shut down the circuit ... looks like my multimeter is sucking all the current available. Not sure if I can trust my instruments.

Happy new year everyone !

Also, just one ground added to full bridge rectifier and one end of output secondary will show a voltage using NCV function of multimeter, although this is not present when output is used rectified or not without a ground. But, when one wire system is used for output where one end is grounded and separate additional ground is used for bridge rectifier NCV function do not detect any voltage ... despite some opinions saying the return wire is replaced by earth grounding.

This is similar with powering lights, resistive elements or motors by using a conductive plate and a ground connection under the power grid lines. If you place too close collector plate you will be loading their system but if you stay further away with collector plate there is no loading. Similar way is to collect "electrostatic charges" from the air produced by a whimhurst machine or tesla coil.

I hope you guys can understand the working principle of no power consumption on the load side, where we can use a low power method to an initial localised huge displacement in local environment. We only need a vibrating electric field (ac or pulsed dc) without any flow as we don't close the circuit.

Also, this system can work with positive grounding or negative grounding, respective using antenna for positive or earth for negative ... which can indicate mobile and respective static solutions.

The main thing is not to load the input ! Output power can be increased obvious now by increasing frequency or voltage or both ... it can be more simple than that. And the beauty is anyone with some knowledge and right equipment can easy test to have a solid proof. Just be mindful using high voltage as in 99% of cases your first mistake is the last one that you'll ever make !

As per Tesla discoveries and later by Don Smith disclosures output power available will increase with square of voltage and square of frequency ... no need to go mad with input voltage from low power source.

I have tested and 20 v input result in 160-170 v output and 24 v input result in over 200 v output using my cheap and limited resources constrained by constant 17.6 khz output from zvs circuit or coils.

@ All,
Welcome in 2025 and a HAPPY NEW YEAR.

@ Member Classic,

Your observations are consistent with principles seen in high-frequency resonant systems and the concepts explored by Tesla and others like Don Smith. Here are some points and advice to further understand and refine your setup:

Key Concepts
Voltage and Frequency Scaling:

According to electromagnetic theory, increasing voltage or frequency in resonant systems can dramatically enhance the power output due to the square-law relationship.Tesla and Don Smith emphasized leveraging resonance and harmonics to extract higher energy from the environment or a given input.

Impedance Matching:
[color=var(--body-txt-color)]The relationship between input and output efficiency depends heavily on how well your circuit components (e.g., inductors, capacitors, and transformers) are matched for impedance.[/color]

Resonance:
Operating your system at the resonant frequency of your LC circuit is crucial. This allows for minimal energy losses and maximum voltage/current amplification.If your ZVS circuit operates at a fixed frequency (e.g., 17.6 kHz), ensure your coils and capacitors are tuned to resonate at this frequency.

Energy Conservation:
While the voltage increases (and thus apparent power), real power must still comply with conservation laws unless additional energy is introduced from the environment (e.g., ambient electromagnetic fields, radiant energy). Recommendations for Refinement

Variable Frequency Drive:
Use a frequency generator or a ZVS driver with an adjustable frequency. This allows you to experiment with different resonant frequencies of your system and observe the results.

Quality Components:
High-quality capacitors (e.g., polypropylene) and inductors with minimal resistance will reduce losses and improve efficiency.

Measurement Tools:
Use precise measurement tools like oscilloscopes and multimeters to verify voltage, frequency, and waveform integrity. Ensure you're not dealing with high-voltage spikes or noise.

High-Q Circuit Design:
A higher Quality Factor (Q-factor) means less energy is dissipated as heat. This can be achieved by minimizing resistive losses in your coils and ensuring tight coupling in your transformers.

Step-Up Transformer:
If voltage step-up is your goal, experiment with transformers optimized for your operating frequency. Using ferrite cores designed for high-frequency applications can significantly improve performance.

Energy Source:
Consider investigating ways to tap into external energy sources or improve energy recovery within the system (e.g., using back EMF or environmental energy capture). Safety First

High Voltage Handling:
Voltages in the range you're working with can be dangerous. Use proper insulation and safety protocols.Be cautious of potential over-voltage conditions that could damage components or create hazardous conditions.

Heat Dissipation:
High-frequency circuits often generate heat in components like inductors and transistors. Use proper cooling measures. Testing and Observation Document your findings carefully, varying one parameter at a time (voltage, frequency, coil design, etc.) to understand their effects on output.Share your results with the community to gather feedback and additional insights.

If you're attempting to replicate Don Smith's devices or similar systems, keep an open mind but remain grounded in empirical observations and safety practices.

Greetings, Alex

Happy new year to everyone !

@kampen , many thanks for your valuable input.

My approach is very different from the advice 

I won't spend money on instruments or tools as I want something that can be done diy at home by anyone with low to medium skills ... if I can't make it, probably more then 90% of those attempting to replicate will fail as well.

After few more tests done today I have decided the direction. In my resonator (ordinary copper pipe) I have observed standing waves so, there is little adjustment to do by moving coils along and change the length of pipe. Second, coil geometry for better capture, or start to improvise capacitor plates if geometry of coils indicate this.

I rather keep fixed frequency as there would be a lot of tuning to do along with other components. As long as my input stays the same and the output do not request more power from providing circuit all is good. I am more than happy to spend few watts to operate a disturbance in local environment and employ an artificial (or natural) gradient.

Radiant energy is the energy that radiate from a single or multiple sources and we only need an efficient method to capture it or better said: to offer a path and let it flow in our devices/appliances.

I have given the example of water ram pump before: we have some water in a river or lake and we need to bring it where we need while leaving natural forces to do the work for us. Now consider the atmosphere where we have an average constant of 100 V per meter altitude above the ground ... there is plenty for any living being on earth and non exhaustible as long as our planet is still around our sun.

Indeed, safety measures are the first rule !
