Self Powered Back EMF Generator

I made lots of advancements over the winter in this field and wish to share my progress on my next invention. More details and some basic diagrams on my youtube video here> https://youtu.be/MsG3xQHQIW8

My invention  is a simple, low-cost, self-oscillating system that harnesses the back EMF of two coils to produce a sharp spike of energy that can be used to power devices or charge batteries.

The system uses only a few components to trigger the feedback loop, including a low voltage zener diode and an SCR (silicon-controlled rectifier) to dump the charge of a flash capacitor into one of the coils

In details, The system is powered by three dry cells, with two of them being integrated into the coils themselves. The coils are wound around magnetic cores, with a thin paper layer in between to act as a dry cell. This setup creates a total of three dry cells, which, when run in series, produce a few volts of power that can be fed back into the system for a back EMF feedback loop. and an SCR diode is used to dump the charge from the capacitor into one of the coils, causing a back emf spike that triggers the system to oscillate. The dry cell acts as a power source, while the coils generate a back electromotive force (emf) due to their magnetic fields. The system is designed to operate as a self-triggering feedback loop, with the triggering voltage of the SCR adjusted based on the output voltage of the coils. The dry cell properties of the coils also create an internal capacitance, which helps the system during "off" times

The addition of a metal core to each coil, with a thin paper insulator between the core and the coil, creates a dry cell effect within the system, effectively doubling the power output of the generator. This is due to the metal cores acting as an anode and cathode, with the thin paper insulator acting as the electrolyte. The voltage generated by the coils and dry cell effect can be added together to create a larger voltage for the flash capacitor to discharge. By using the magnetic cores as dry cells in addition to the paper, the voltage difference between the two coils can be increased, creating a larger voltage output.

It's important to clarify that the "dry cell" in this invention is not a traditional dry cell battery that we commonly use in electronics. Instead, it refers to the phenomenon of creating a voltage potential using a metal core and a thin paper insulator as an electrolyte.

This phenomenon occurs due to the presence of moisture in the air. The thin paper insulator, which is typically made of cellulose, is hygroscopic, meaning it readily absorbs moisture from the air. When this moisture comes into contact with the insulator, it creates a conductive path between the metal core and the coil, allowing for the flow of electrical current.

As the generator operates and produces back emf, the dry cells become charged, providing additional power to the system. This helps to ensure that the generator can continue to operate, even when the dry cell battery runs low or is depleted. When an alternating current flows through one coil, it generates a magnetic field that fluctuates in strength and direction. This fluctuating magnetic field induces an alternating current in the second coil, which is placed in close proximity to the first coil. This phenomenon is known as mutual induction.

The back emf feedback loop is an essential part of the generator, as it allows the system to continue generating power without the need for an external power source. By carefully tuning the values of the components involved, a stable and efficient feedback loop can be established, resulting in a steady stream of electrical power.

To ensure a stable oscillation, a compensator voltage system can is implemented to adjust the triggering voltage of the SCR based on the output voltage of the coils. This helps maintain a consistent feedback loop, allowing the system to operate continuously.

this system is a promising approach to harnessing the energy of back EMF for practical applications. The use of dry cells integrated into the coils themselves, along with the addition of the paper layer, provides a simple and effective way to generate power and trigger the back EMF spikes. With further development and optimization, this system could have a wide range of potential applications in areas such as renewable energy, wireless power transmission, and more. This is why I feel like I must share my research as I go along.

Wireless power transmission using electromagnetic fields has the potential to revolutionize the way we power and charge our devices, and my invention offers a breakthrough in this field. By utilizing the back electromotive force (back emf) generated by the coils, an oscillating magnetic field can be created and received by a resonant coil tuned to the same frequency. This enables multiple devices to be wirelessly powered or charged simultaneously, without the need for cumbersome cords or charging pads.

Moreover, the excess energy generated by the back emf can be harnessed for wireless power transmission to nearby devices. This is achieved by employing a resonant coil in the transmitting device to create an oscillating magnetic field that can be received by a resonant coil in the receiving device. This energy can then be converted into electrical power, offering a seamless and efficient way to power our devices.

As such, my invention offers tremendous potential to be a key component in making wireless power transmission a reality. With the ability to wirelessly transmit power to multiple devices at once and the potential to harness excess energy for further power transmission, the possibilities for this technology are endless. This breakthrough has the potential to significantly impact our daily lives and offers a sustainable and efficient solution to powering our devices.

my invention does not violate the laws of thermodynamics because it does not create energy out of nothing. It harnesses the energy that is already present in the magnetic fields generated by the coils, and converts it into usable electrical energy through the use of the back emf feedback loop.

The generator does not draw energy from its surroundings or nearby systems, but rather uses the energy that is already present in the system itself. The dry cell acts as a power source, and the generator converts the energy from the magnetic fields into usable electrical energy.

The back emf feedback loop is also an example of the conservation of energy, as it allows the excess energy generated by the system to be fed back into the system itself, increasing its overall efficiency.

Therefore, this invention operates within the boundaries of the laws of thermodynamics, by converting energy that is already present in the system into usable electrical energy, without violating the principle of conservation of energy.

My invention could potentially help solve the problem of charging electric cars. With wireless power transmission using electromagnetic fields, it is possible to wirelessly charge electric cars while they are parked, without the need for cables and physical charging stations. My invention, with its ability to generate back emf and excess energy, could be used to wirelessly transmit power to electric cars equipped with resonant coils.

This would allow for more convenient and efficient charging of electric cars, without the need for drivers to actively seek out charging stations or plug in their cars. Additionally, this could help address issues related to limited charging infrastructure and range anxiety, which are major concerns for electric car adoption

Just something to think about........

Hello
you could draw a schematic. How should the coils be wound up? I would like to build it.
Greeting
Lota
Is it this one?

If you can feed back a 6V100mA energy.
Then pick up a battery and start it perfectly.

No that is something else, You need to experiment with different coil types, Like maybe build the 2 coils in rectangular shape so you can put them close together with the dry cell thin paper electrolyte in the middle. Make sure the 2 windings are  wound in opposite directions, and it should be off to a good start.

There are few methods to build this if you understand the backgrounds. No schematics i'm not there yet.  How ever I know it works as I shown some people who really know about this stuff some demos and prototypes I got at home of the various sections and stages of such a device,

And no one up to date has been able to challenge and say that will never work because my device clearly does not violate any rules of physics and thermodynamics.

This is more of an update post explaining what i'm up to and perhaps inspire along the way. I'm still in 6 feet of snow here in Northern Canada can't wait to get the usage of the backyard to stick some ground rods and start experimenting with bigger stuff.

What i'm getting it as I got something but its not in presentable form as a complete unit yet. It's a working on project based on my other previous projects.  The challenge I face how-ever not impossible is to carefully tune the components so that the back emf can feed back and forth between the 2 coils and self trigger.  There are a few mechanisms im currently experimenting with such as the scr dump methods and voltage compensator.

This device can later be perfected and built into a wearable version. The wearable version of my invention involves using the human body as an electrolyte in between two wearable coils that trigger a back EMF spike. This works similarly to how original idea works, but instead of using a thin paper in between the two coils, the body would be used as the electrolyte.

To make this work, we need to modify the coils and make them wearable in some way. The wearable coils generate back EMF and work in a feedback loop with two coils to trigger the back EMF spike. This would wirelessly charge devices such as cell phones, tablets, and small laptops in pockets and bags near the body where the wireless radiates.

The human body would not be the power source, but rather used as a low voltage trigger pulse to start the back EMF spike feedback loop. As long as the frequency is kept safe for humans and the current is not too high, it could be explored as an alternative option to wireless charging.
