Resonance and high frequency

Nothing at the archive but a page that says domain may be for sale.

My bad, it was wayback machine: https://archive.org/details/24739145ResonanceEnergyMethodsByDonaldLSmith/mode/1up

Now compare this info with what is available from Patrick Kelly book.

I am quite reluctant to post were files can be found as it seems everything is scrubbed down or replaced with misleading info.

Also, I have noticed some particular interest about old books/files/patents, but not necessarily about the info ... the request is for the source of the info, like someone want to make sure everything is rooted out.

I have seen the same pattern regarding mono atomic hydrogen power calculations, where scientific data was simply replaced with eronate data.

If anyone wants to try their hands on, there is some clues based on my setup as described earlier: 2 m long copper pipe 15 mm diameter (used for home heating system with radiators).

But, using small segments of copper pipe may make the whole setup much easier and practical, all coils must have only one end output and second output wire will be an earth wire. Due to high frequency is much easier to rectify this output and use as DC or with an inverter for AC ... but it may well worth to try to obtain some resonance in output coils and calculate what capacitor is needed, than rectify. Capacitor should be fitted across the output from coils and earth wire.

Copper pipe must be insulated, I have used some teflon tape (for plumbing, 0.075 mm thick) to increase capacitance, but good quality electrical tape can be used as well. My pickup coils are made of 0.5 mm diameter magnet wire (enamelled solid copper wire).

All connections must be done very well soldered where possible or high quality crimps.

I have tried some aluminium cans instead of copper pipe and they might work as well, but the setup becomes too bulky.

Not sure yet how many small length pipes I can put together ... probably many more until resistance become a restrictive factor.

Here are the resistance calculations for the full-length coil and setups with 4, 8, and 16 coils:

• Single Coil (183 m total length):
  
  
  • Coil Length: 183.0 m
  • Resistance Per Coil: 15.66 Ω
  • Total Resistance: 15.66 Ω
• 4 Coils (45.75 m each):
  
  
  • Coil Length: 45.75 m
  • Resistance Per Coil: 3.91 Ω
  • Total Resistance: 0.98 Ω
• 8 Coils (22.875 m each):
  
  
  • Coil Length: 22.875 m
  • Resistance Per Coil: 1.96 Ω
  • Total Resistance: 0.24 Ω
• 16 Coils (11.4375 m each):
  
  
  • Coil Length: 11.4375 m
  • Resistance Per Coil: 0.98 Ω
  • Total Resistance: 0.061 Ω

Analysis

• Single Coil Setup:
  
  
  • The high resistance of 15.66 Ω limits the current significantly, reducing overall efficiency.
• 4-Coil Setup:
  
  
  • Total resistance drops to 0.98 Ω, offering a substantial improvement. This setup balances practicality (fewer coils) and reduced resistance.
• 8-Coil Setup:
  
  
  • With a total resistance of 0.24 Ω, this configuration provides even higher current availability. However, it requires more wiring and connections.
• 16-Coil Setup:
  
  
  • The resistance is drastically reduced to just 0.061 Ω, maximizing current output. While this setup achieves the best performance, it may be more complex to implement due to increased coil count and connections.

Recommendations

• The 4-coil setup offers a good trade-off between simplicity and performance, reducing resistance by over 15 times compared to a single coil.
• For maximum current output, the 16-coil setup is ideal, though it involves greater effort to construct and manage connections.

How to scale up ? Few ways: multiple rods with pickup coils; voltage increase in input circuit; frequency increase in input circuit. Always keep an eye on your input and make sure you are not going to draw more power than in needed to run your input circuit empty !

Using that cheap zvs circuit gives about 60v output with 20Vdc input under 1 amp, my system runs empty for 5-6 watts. Input (providing) circuit must not be closed !

Shall we play a bit with Ohm's Law ?

Let's consider 220 V rms ... this is approx 160 V DC ready to collect from pickup coils ... actually we can consider some losses as there wouldn't be a perfect capacitive coupling and assume we can get approx. 140 Vdc.

Now let's see what we can get: 140 Vdc / 0.061 ohms = 2295 amps, now let's assume we have unforeseen losses of 50% and we can only get 1150 amps at 140 Vdc.

For the moment I only have one pickup coil done and before being able to take any readings to check power consumption I just toasted my last resistors as I only have cheap resistors 1/4 watts and there is not yet enough current to lit up any bulbs.

Of course I have improved a bit the setup adding an layer of insulation tape on top of pickup coil then 2 layers of thin kitchen aluminium foil and another layer of insulation tape and left out a little bit of aluminium foil to add a ground.

This is the best outcome scenario that has to be tested.

P.S. in the message above note that the output from zvs is 60 V, but in secondaries is 60v per coil !

Some thoughts about the rod/tubes material:

Copper isn't the best materials to resonate, while brass is used in musical instruments if someone is looking for even more improvements and is willing to pay a bit more.
