Invitation to Join Open Research on RWG for Wireless Energy Harvester Circuit

Hello RWG Research Members,

We are embarking on an exciting open research project, and we invite you to participate, collaborate, and innovate on a cutting-edge Wireless Energy Harvesting System. This project revolves around a rectenna (rectifying antenna) and power conditioning circuitry that captures and converts ambient electromagnetic energy into usable electricity. Whether you're passionate about renewable energy, wireless power transfer, or electronics, this project has incredible potential, and we need your expertise to help test, improve, and optimize the design.

Here’s a detailed breakdown of the system we're working on:

1. Rectenna (Rectifying Antenna) Energy Harvester
The rectenna is the heart of our energy harvesting setup. Its function is to capture electromagnetic radiation (such as RF energy, Wi-Fi signals, or other ambient energy sources) and convert it into direct current (DC) electricity. This conversion occurs through:
Design to be mass production up to 1000 rectennas could be series wired and joined together to make a large panel.
This also could Extract from Liquid such as salt water. Or Nano Bubble Water Fuel.

Diodes (1N34, 1N4148): These components rectify the alternating current (AC) signal gathered by the antenna, turning it into DC electricity. Diodes allow current to pass in only one direction, ensuring efficient conversion.
Capacitors: These store energy temporarily and help smooth the DC output, stabilizing it and making it ready for further use.
Array Structure: The rectenna consists of multiple diode-capacitor pairs arranged in a grid to maximize energy collection and improve efficiency. Notes we can put a Additionally Large Aluminum back plate on rectenna flat plate, or or a  spiral Lilly impeller copper tube  in top of a pyramid to gather power both work find and are just ways to  add electron gain. shape

2. Power Receiving Board
Once the rectenna collects energy, it’s passed to the power receiving board. Here, the system performs additional voltage regulation, increasing the energy's utility:

Impedance Matching Circuit: To ensure that maximum power is transferred from the rectenna to the rest of the circuit, the impedance matching circuit minimizes energy loss.
Dickson Voltage Doubler: This clever circuit uses a combination of capacitors and diodes to increase the voltage, making the harvested energy more usable for various applications.
Capacitors and Diodes: These components stabilize the voltage and protect the system from surges and fluctuations, ensuring safe and consistent power delivery.

3. SMA Connector
The SMA (SubMiniature version A) connector provides a high-efficiency link between the rectenna and the power board, allowing the signal to be transferred with minimal interference or loss. It ensures reliable connectivity for high-frequency signals, making it ideal for energy harvesting systems.

4. Buck Converter
A DC-to-DC buck converter takes the rectified energy and steps down the voltage to a more usable level. Whether you're powering a small electronic device or charging a battery, the buck converter allows you to adjust the voltage from the incoming 12V DC down to a range between 1.25V and 48V, making it adaptable to a variety of applications.

5. ZVS (Zero Voltage Switching) or Stanley Meyer Circuit
The final output from the power board can drive a ZVS circuit—an efficient system for powering inductive loads or enabling wireless power transfer. The Stanley Meyer circuit can also be employed for hydrogen voltrolysis, breaking water molecules into hydrogen and oxygen using high-frequency pulses.

6. Diodes, Capacitors, and Other Parts in the Circuit
Diodes ensure the smooth flow of energy, preventing reverse current, which could otherwise damage the circuit.
Capacitors store and stabilize energy, allowing the system to quickly release charge when needed.
Zener Diodes help regulate the output voltage, preventing over-voltage conditions that could damage sensitive electronics.

7. DC Output
The system produces a stable DC output that can be used to drive other circuits, charge batteries, or store in capacitors. The versatility of this system makes it suitable for many applications, from powering electronics to wireless power transmission and renewable energy storage.

Summary of System Operation:
Energy is captured by the rectenna and converted from AC to DC via diodes.
The DC signal is stabilized and processed by the power receiving board, which steps up the voltage if necessary using the Dickson voltage doubler.

The SMA connector links the two boards, ensuring efficient energy transfer.
A buck converter steps the voltage down to the appropriate level for further use.
The system outputs a clean, stable DC current ready for use in driving loads or powering other systems, such as a ZVS circuit or Stanley Meyer voltrolysis setup.

We have Designed to handle the Following

"Rectenna Energy Harvester" by Quanta Magnetics.

VOLTS

It features Schottky diodes (M4AET617) and capacitors (63NF, 50V). Here's a general guideline for understanding its capacity:
Single Board Capacity
Diodes: The M4AET617 Schottky diodes are typically rated for low forward voltage and can handle a few hundred milliamps to several amps, depending on the specific model.
Capacitors: With a 50V rating, these capacitors are designed for relatively low power applications.

Power Handling
Amps: Each diode's current handling capacity is crucial. Assuming a typical Schottky diode rating, it might handle around 1-3 amps.
Watts: Power (in watts) can be calculated using
P=V×I
P=V×I. Without specific voltage input details, it's hard to give an exact wattage.
Series Configuration (10 Boards)

Amps: In a series configuration, the current capacity remains the same as a single board.
Voltage and Watts: The voltage capacity increases linearly with the number of boards. Therefore, if each board handles 50V, ten boards in series would handle up to 500V. The total power capacity would be
P=500V×I

===================================

AMP and WATTS

To calculate the amps and watts the board can handle, we need to consider the components used:
Single Board Capacity
Diodes (M4AET617 Schottky Diode):
Typical current rating: around 1-3 amps.
Voltage drop: approximately 0.3V (common for Schottky diodes).
Capacitors (63NF, 50V):
Voltage rating: 50V.
Power Calculation for One Board
Current (Amps): Assuming the diodes can handle up to 3 amps.
Power (Watts): Using
P=V×I
, if we assume a safe working voltage of around 10V (for low-power applications):
P=10V×3A=30W

Series Configuration (10 Boards)
In a series configuration:
Current (Amps): The current remains the same as a single board, so up to 3 amps.
Voltage: Increases linearly with the number of boards. If each board is safe at around 10V:
Total Voltage
=10×10V=100V
Total Voltage=10×10V=100V
Power (Watts):P=100V×3A=300W

My calculations are based on typical values and assumptions.
For precise ratings, refer to the specific datasheets of the components used.

To improve the board for capturing more power or handling a larger load,
please consider the following enhancements:

Component Upgrades

Diodes:
Use diodes with higher current ratings to increase the overall current capacity.
Consider using diodes with lower forward voltage drop to reduce power loss.

Capacitors:
Increase the capacitance value to store more energy.
Use capacitors with higher voltage ratings if the input voltage might exceed current limits.

Circuit Design Improvements

Parallel Configurations:
Add parallel paths to increase current capacity without increasing voltage.

Heat Management:
Implement heat sinks or thermal pads to manage heat dissipation, especially if higher currents are used.

PCB Traces:
Widen PCB traces to handle higher currents and reduce resistance.
Material and Layout

Substrate Material:
Use a substrate with better thermal conductivity to improve heat dissipation.
Component Layout:

Optimize the layout to minimize resistance and inductance, which can improve efficiency.
By making these adjustments, you can enhance the board's ability to capture more power and handle larger loads effectively.

Remember
Move without a motor,
Shine but cast no light,
Split the unseen atom,
Leave no trace in sight.

Fuel what can’t be powered,
Hold what can’t be held.
No matter your Master
Change can't be quelled.
For innovation  can not be dispelled.

For those who see beyond the veil,
Quit your employer's chains, and embrace what's real,
Join the common good, unite and heal the suffering.

The path is ours to forge, the future ours to claim—
Together, we rise, unbound by any one who may want to tame.

This is very interesting... my main issue with this concept is, what do we do if RF goes dead and Wifi goes dead, its syphoning power off of existing manmade power sources. Don't get me wrong its a great idea, and I love it tbh, its very interesting and I've heard of people making various types of antennae to do this and it really can work.

It doesn’t rely on man-made Wi-Fi or RF signals.

Sometimes, the reality of how it works is too overwhelming for those conditioned
to dismiss what they don’t understand. They often react with disbelief, thinking, "It couldn’t possibly be that simple!"

The Purpose is Constant recharging of Caps and Battery banks and scalable application.

The greater world is waking up. Build it. USE it Spread it. Godspeed.

And Remember
Daniel Donatelli Secure Supplies Made it and Shared it .

I don't doubt it but was wondering what frequencies its receiving the energy from and what the source of them are? I understand you can create circuits that resonate with existing RF / Wifi signals but they are coming from somewhere. Does this harness natural frequencies that are occurring in nature then I'm guessing?

We Live in a Sea of energy

we can add a variety of balun and literally tune to everything
whether natural or man made  having very basic understanding simply means you know how to adjust for you particular elevation or area resources
minimum 9 to 1  or 1 to 9 put between rectenna board and energy harvest circuit

Notes
Using a tuning balun with your rectenna PCB can be beneficial, depending on the specific application and design requirements. Here are some considerations to help you decide:
1.   Impedance Matching: A tuning balun can help match the impedance of your rectenna to the load or antenna. This matching is crucial for maximizing power transfer and improving efficiency.
2.   Frequency Response: If your rectenna is designed for a specific frequency range, a tuning balun can help enhance its performance by providing a better match across that range.
3.   Noise Reduction: Baluns can help minimize common-mode noise, which can be particularly important in RF applications.
4.   Space and Design Constraints: Consider the size and layout of your PCB. If space is limited, you may need to evaluate whether a balun is feasible within your design.
5.   Cost and Complexity: Adding a balun may increase the cost and complexity of your circuit. Make sure that the benefits outweigh these factors.
If you're unsure, it can be helpful to simulate your circuit with and without the balun to see how it affects performance. Ultimately, the decision will depend on your specific application and design goals.
 
When choosing between a 9:1 and a 1:9 balun for your rectenna PCB, it depends on the specific design requirements and the impedance of your rectenna and load. Here’s how to make a decision:
9:1 Balun
•   Use When:
o   Your antenna (or rectenna) has a lower impedance (e.g., 50 ohms), and you want to match it to a higher impedance (e.g., 450 ohms) for a specific application.
o   If you're working with a small signal that needs to be amplified and the rectenna operates at a lower frequency.
•   Benefits:
o   More common in many RF applications for matching lower impedance antennas to higher impedance loads.
1:9 Balun
•   Use When:
o   Your antenna or rectenna has a higher impedance (e.g., 300 or 450 ohms) and you want to match it down to a lower impedance (e.g., 50 ohms).
•   Benefits:
o   Useful for matching higher impedance antennas directly to common RF input or receiver circuitry.
Size Considerations
1.   Core Material: Use a core with a suitable permeability for the frequency of operation. Ferrite cores are commonly used, but the type (e.g., mixed ferrite, air core) will depend on your frequency range.
2.   Turns Ratio: The size of the balun can be influenced by the number of turns on the primary and secondary windings. More turns generally lead to better impedance transformation but increase the size.
3.   Frequency of Operation: Make sure that the balun is designed for the frequency of your application. The dimensions and materials will vary based on the operational frequency.
4.   Physical Size: Ensure that the size of the balun fits within the design constraints of your PCB. Baluns can range from compact (like SMT components) to larger (like toroidal cores).

General Recommendation
For a rectenna, if you’re matching a typical 50-ohm load (like RF receivers), a 9:1 balun is often more appropriate. However, if your application involves a higher impedance signal that needs to be brought down to 50 ohms, a 1:9 balun would be suitable.
If possible, consult the specifications of your rectenna and the impedance characteristics to make the best choice. You might also consider simulation tools to see how each configuration performs in your specific design scenario.

  Also I might add use a RF emf Meter and or  swr meter to measure what you have where you are what you get and what you backing plates antenna add on are doing so to know the khz mhz you looking at.  some ferrite can add to the tuning process depending on your design all work.

notes
Additional Compounds and Ferrite Materials
To achieve optimal performance, exploring other magnetic materials and their frequency characteristics is essential. Here are some additional options beyond MnZn and NiZn ferrites:

Material   Frequency Range   Permeability (μ)   Key Characteristics
Amorphous Metals   50 kHz – 10 MHz   500 – 100,000   Very high permeability, low core loss at high frequencies. Ideal for compact, efficient transformers.
Nanocrystalline Ferrites   50 Hz – 100 kHz   10,000 – 150,000   High saturation flux density, stable at high temperatures. Ideal for efficient energy conversion at low frequencies.
Cobalt-Based Alloys   1 kHz – 10 MHz   100 – 10,000   High saturation flux and low loss; good at high frequencies.
Soft Iron   1 Hz – 10 kHz   Up to 5,000   Very high permeability, but high loss at higher frequencies. Suitable for low-frequency applications.
Nickel-Iron Alloys (Permalloy)   DC – 1 MHz   50,000 – 100,000   Extremely high permeability, great for low-frequency and low-power applications.

I got acquainted with high-freq rectifiers (100-200kHz neighborhood), setting up the RX end of my 'single wire transmission line'; this looks like something I might be able to use as a 'learning project' to great effect, cool idea! These are not so different from some of the more elaborate 'avramenko plug' type rectifiers I've made. A lot of rectennas can operate like 'single wire' devices too. I might just see what kind of wattage I could pull from the field nearby a helical tesla coil lol. Thanks for the gerber file!
