This project explores the creation of an energy harvester (AEFC) that taps into ambient electromagnetic fields (EMFs) The goal is to create a portable system capable of collecting and converting energy from the surrounding environment.

The Ambient Energy Field Converter (AEFC) is an experimental project exploring unconventional methods for capturing, storing, and utilizing ambient energy from natural and artificial sources.

The system combines inductive elements, capacitive components, and custom circuit architectures to harvest energy from Earth's ground potential, nearby electromagnetic fields (EMF), and potentially other overlooked ambient influences.

Unlike traditional energy harvesters, the AEFC exhibits behavior that appears sensitive to capacitive touch, and environmental fluctuations in various energy fields. This opens up a new class of ambient-reactive designs, where circuit performance changes dynamically in response to local conditions—including the presence of a human body.

The project focuses on:
- Capturing ultra-low power signals from passive sources
- Enhancing circuit sensitivity and tuning energy pathways
- Exploring novel coil configurations and interactions
- Improving storage and transfer efficiency of harvested energy

Component lists are evolving and not exhaustive. The project is in active development, with discoveries emerging through direct experimentation and iterative design.

  • Voltage Anomalies During Human Interaction with Coil Array

    Rhea Rae5 days ago 0 comments

    I had a hard time falling asleep last night because this strange behavior wouldn’t leave my mind. When I touched the coil and watched the voltage shift—sometimes up, sometimes down depending on the coil—I realized I wasn’t just testing the system, at that moment I was part of it.

    I observed more unusual behavior in my AEFC coil array that strengthens the idea that the system may be interacting with my body capacitively, and perhaps even through more complex ambient field dynamics.

    While testing AC voltage between different combinations of the three primary coils, I noticed that simply touching one of the coils with my finger caused a measurable and repeatable voltage change on the meter. In some coil pairings, the voltage increased when touched; in others, it decreased. This behavior was consistent across all coils and combinations, suggesting this isn’t just static buildup or random environmental noise.

    There are several implications here:

    1. My body seems to be acting as a capacitive element in the system, introducing or sinking charge depending on how it's interacting with the existing coil fields.

    2. The AEFC coils may be coupled magnetically, capacitively, or both. This coupling appears to be sensitive enough to shift behavior simply by the presence of a nearby conductive mass—in this case, me.

    3. The voltage shifts aren't consistent in direction, which implies a complex relationship between mutual inductance, capacitive coupling, coil orientation, and local grounding paths (likely including my own body's grounding state relative to Earth).

    In this configuration, I am not simply a bystander. I am part of the circuit. And the AEFC system seems to be reactive in the truest sense of the word—its behavior dynamically shifts when a human interacts with it.

    This lends further weight to the idea that the AEFC is not just harvesting ambient energy passively, but may also be behaving as a field-sensitive system, where body capacitance and/or local EM fluctuations play a role in shaping the energy dynamics.

    This kind of body-sensitive circuit behavior may be hard to replicate without the same AEFC layout, same component conditions, and even the same human interactions. But it deserves close attention—because it hints at a category of nonlinear, ambient-reactive circuits that might be overlooked by conventional test setups.

  • Unconventional Series LED Illumination via Coil and Human Contact

    Rhea Rae5 days ago 0 comments

    Today I was experimenting with my coil setup using an unusual configuration and observed faint illumination in a blue LED with no external power source.

    The LED and an electrolytic capacitor were arranged in a nontraditional series configuration. I touched the cathode of the LED with my hand, the anode of the LED was connected to the negative (cathode) of the capacitor, and the positive (anode) of the capacitor made direct contact with the test coil. Only when this chain was complete did the blue LED glow very faintly.

    This test was performed on all three coils, and the effect was consistent across each one. That consistency suggests the result isn’t limited to coil geometry or placement—it appears to be a repeatable interaction, likely influenced by environmental EM fields and body capacitance.

    Of the three LEDs tested, the blue LED (VF 3.0–3.2 V at 20 mA, 460–470 nm) produced the brightest glow., yet still very dim. The green LED showed only a very dim response, while the red LED did not illuminate.

    This result may point toward a combination of inductive coupling, ambient field harvesting, and human capacitance, potentially aligning with directional energy transfer behaviors. 

    Yet another observation I cant fully explain.

    Components used:
    Clear Blue LED – VF 3.0–3.2 V, IF: 20 mA, 460–470 nm
    Electrolytic Capacitor – 0.10 µF

  • Stepped AC Pulse Observed During Coil 3 Measurement

    Rhea Rae06/04/2025 at 16:07 0 comments

     While measuring AC voltage between the positively DC-biased Coil 3 and the negative terminal of the main capacitor, I observed a repeating and distinctive stepped pulse. The waveform cycled from 0 volts to approximately 5 volts AC, returned to 0, then surged to around 46 volts AC before falling back again—repeating this pattern with consistent rhythm. In contrast, when measuring from Coil 1 or Coil 2 to the same capacitor terminal, the voltage held steady at about 3 volts AC, with no pulsing or dynamic changes observed.

     This stepped behavior seems to be more than random fluctuation or environmental interference. It may indicate some form of sequential energy movement, potentially triggered by magnetic field changes or differences in coil behavior under DC bias. The rhythmic, layered nature of the pulse suggests the possibility of staged interactions between components—though further testing will be required to understand the exact mechanism at play.

     A short clip of the AC voltage reading has been uploaded to the files section for review. As always, it’s possible I’m misinterpreting what I’m seeing, and this remains just an observation at this point. But it’s definitely one worth noting and investigating further.

  • Super Capacitor Storage Bank (SCSB) Milestone

    Rhea Rae05/30/2025 at 15:21 0 comments

    The SCSB has officially hit 8VDC—well, 8.07VDC, to be exact! Yet another little milestone worth taking note of.

    Now, if I could just decide what exactly I want to do with this contraption. I’ve already lit an LED (because of course I did), and made some sparks too—but come on, I want it to be useful, to serve a real purpose.

    When I look back, it’s kind of wild. I started by scavenging minuscule traces of electricity, just seeing what I could pull from the environment. Then I built, experimented, adjusted, and tuned—again and again—until I ended up with something that can actually store a reasonable amount of energy.

    Now that it's doing just that... what’s next I ask myself as it continues to accumulate energy?

    This update serves as a broad reflection on the current progress of the Ambient Energy Field Converter (AEFC) project.

    The AEFC is a multi-layered experiment in passive energy harvesting and long-term storage. The system is designed to collect ambient energy—without the use of solar panels or active RF injection—and store it using both traditional capacitors and a supercapacitor bank.

    Before integrating the supercapacitors, the system reached a peak of 32VDC on a standard capacitor, confirming a strong ability to accumulate ambient voltage. After adding the supercapacitor bank, voltage levels naturally dropped due to increased capacity but have continued to rise steadily, now reaching 7.78VDC. This slow, consistent gain demonstrates the system’s ability to continue harvesting and banking energy over time, even under load.

    The AEFC has already powered LEDs, including a blinking setup, proving energy output beyond simple storage. As expected, shorting the supercapacitor bank produces a visible spark—further evidence of substantial energy retention. While the system cannot yet sustain output for long durations, it has shown a working capability to collect, store, and release energy. This creates a foundation for potential low-power applications such as timed pulses, sensors, or signaling devices.

    While grounding clearly improves charge accumulation—likely due to capacitive coupling with AC field energy—the AEFC also continues to accumulate charge in a floating, ungrounded state. This strongly supports the conclusion that the system is capturing energy from multiple ambient sources, including RF and localized field interactions. The AEFC is not dependent on any one harvesting condition, and instead reflects a hybrid behavior across both field-referenced and field-independent sources.

    The next logical steps involve tuning, scaling, and defining the long-term purpose of the system. There are still many phases ahead, and each one will bring the project closer to its potential.

HI Rhea, interesting project.  I have a lot of solar energy harvesting projects that store their energy in li-ion battery, supercaps and lithium ion capacitor. I am fan of the last one. These days you can buy 250F 3.8V lithium ion capacitor for less than 2 dollar from lcsc. They have 5 times less leakage as supercaps, which is relevant for so low energy harvesting. In addition they are safe, they dont burst into flames and have no shipping restrictions like lithium ion batteries And now there are even 4.0V and 4.2V lithium ion capacitors with 1100F and 1300F capacitance. This way you can build a high voltage large storage bank.

Hi Jasper!

Thank you so much for taking the time to comment and share your experience—especially around lithium-ion capacitors. That’s an area I honestly haven’t explored much yet, but your input really sparked my curiosity. I’ve started digging into some sources, and you’re absolutely right—the pricing on LCSC is surprisingly accessible.

I’m still learning about the performance characteristics, especially compared to supercaps and batteries. The lower leakage and lack of shipping/fire restrictions definitely sound like major advantages. I do have a bit of hesitation with ordering from LCSC at the moment due to the current tariff situation—and to be honest, I’m still figuring out how customs works on these types of shipments.

Thanks again for pointing me in this direction, and feel free to comment or message me anytime!

Hey Rhea, interesting work! I've long wondered with ultra-low-power electronics being so ultra-low-power if it's possible to harvest enough energy from the ambient fields to power something mildly useful! If you're looking for some way to more precisely measure the success of your experiments, you may want to check out my project. It can accurately measure current as low as a few nanoamps and allow you to see it in realtime so you can adjust and optimize - maybe it would be helpful? https://hackaday.io/project/193628-metashunt-high-dynamic-range-current-measurement

Hi Jake,

Thank you so much for the thoughtful comment! I really appreciate your insight and encouragement — you're absolutely right, the ultra-low-power device space has become incredibly efficient. That’s one of the main reasons I’ve been diving into this: I’m curious to see just how much "useful" power can be coaxed from small, passive sources.

Your Metashunt project looks amazing — having real-time visibility into ultra-low currents would be incredibly valuable for tuning my harvesting circuits, optimizing capacitor behavior, and spotting losses that are otherwise impossible to detect.

I’ll definitely be taking a closer look. Thanks again for sharing it — and for the kind words!

If you have any questions or suggestions, feel free to message me anytime.

All the best.
