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.

This project explores a method for capturing, storing, and utilizing ambient energy from various natural and environmental sources. The system leverages inductive elements, capacitive components, and strategic circuit design to harvest energy from both the Earth's ground potential and electromagnetic fields (EMF).

By tuning and optimizing energy pathways, this harvester demonstrates the potential for capturing small, otherwise untapped energy sources.

Further experimentation focuses on improving the stability and efficiency of the energy collection process, refining circuit architecture, and enhancing energy storage capacity.

    The AEFC supercapacitor bank just passed 7VDC and is continuing to climb—It seems on track for full 16V charge using ambient energy alone. When I started this, I couldn’t even charge a 10μF cap…

    I checked the SCSB today and the voltage reading shows 5.46 Vdc. The 2200 uf harvest capacitor is at 5.51 Vdc, The voltage differential showing that the regular capacitor is indeed charging the SCSB.

    Well I ended up getting sick randomly, Again...

    The harvester has been sitting about a week and I haven't been in to look on it or work on it, till today. I checked the voltage on the SCSB and it read 4.39 vdc. The 2200uf cap that comes off the full bridge reads 4.42 vdc, there's my voltage differential. Finally something good, Its still working and I will slowly keep tuning and experimenting.

    Sadly I am only able to get 3.3 vdc stored in the 16vdc super cap bank. It was 30vdc with a normal electrolytic capacitor, I do understand why and I had presumptions that this would happen and it means I have more tuning to do, and more research on resonance also. Resonance is something that I am still struggling with in other projects too and I wish someone could help explain this to me as there's only so much I can interpret from AI and Human experience in invaluable. I might then utilize my FY6900 frequency generator finally...

  • Observations within circuits

    My harvester is more than just a circuit—it's a network of circuits within circuits, a testing ground for exploring low-energy potential. It continues to evolve, challenging and expanding my understanding of physics and electrical theory. Born from pure curiosity and driven by my endless pursuit of knowledge, it pushes the boundaries of what I know, revealing new insights with every new experiment.

    IR LED Behavior, Charge Transport, and Possible Quantum Effects

    Recent testing on my energy harvester has revealed an unconventional energy transfer mechanism involving an IR LED that remains fully positive-biased while facilitating voltage transfer without illumination. The IR LED is electrically isolated on both sides by diodes, ensuring unidirectional current flow, yet energy continues to pass through the circuit. This behavior suggests an alternative charge transport mechanism beyond standard diode conduction.

    Observations

    The IR LED remains fully positive-biased, meaning its anode and cathode are both at positive potential, yet it still enables voltage transfer without measurable current draw.

    The LED is isolated on both sides by rectifier diodes, which enforce controlled, unidirectional energy flow, preventing traditional backflow.

    Compared to other LEDs tested, the IR LED demonstrates the highest efficiency, exhibiting the lowest voltage drop while still permitting charge movement.

    This suggests that charge carriers—electrons and holes—are interacting within the LED junction in a nontraditional way, potentially through quantum tunneling or weak conduction mechanisms.

    Charge Transport & Hole Theory

    In a standard forward-biased LED, electrons from the n-type material recombine with holes in the p-type material, releasing energy as photons (light).

    However, in this setup, the LED does not illuminate, yet voltage transfer occurs. This implies that electrons may be filling available holes in the p-layer without sufficient recombination energy to produce light.

    If quantum tunneling is involved, charge carriers may be bypassing the depletion layer, allowing energy transfer without significant current flow.

    This could suggest a low-energy charge movement mechanism, where electron-hole interactions occur at a sub-threshold level, facilitating energy flow without photon emission.

      When I think about it, I started with a simple 10µF capacitor storing just 1-3VDC. Then, I moved up to a 2200µF capacitor holding a steady 30VDC. Now, I'm experimenting with supercapacitors, aiming for even better power densities—but only time will tell. What began as a simple observation has grown into a full-fledged project over time.

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.
