Update from the PrimerField Foundation
August 26, 2025
We want to provide an important update to those who have followed our work at the PrimerField Foundation.
The PrimerCube: From Open Source to Missed Opportunity
In 2019, after many years of research and development, we made the decision to release the full design of the PrimerCube as an open-source technology. As announced in our YouTube video, the goal was to encourage broad adoption by individuals, manufacturers, and researchers who saw potential in the design and underlying PrimerField principles.
For more than five years, we kept that open-source model in place. The complete design remained freely available on our website, and our hope was that larger organizations would begin manufacturing the original PrimerCube in quantity.
Unfortunately, this never happened.
Aside from a small group of hobbyists, only one company—a small manufacturer in the Czech Republic—attempted to commercialize the PrimerCube. While they initially claimed to follow the original design, we later discovered they had made significant changes to the geometry and construction. These changes, in our view, affected the integrity of the array and its field characteristics.
The company based in the Czech Republic initially gave us the impression that their imitation of the PrimerCube was producing results similar to those we had observed with our original design. However, by the spring of 2024, we began receiving emails from individuals who had purchased their version and reported no noticeable effects—and in some cases, described unexpected negative experiences.
We reached out to as many users of the Czech-made units as we could. To our dismay, we did not receive a single report from a user of that product indicating meaningful benefit. This contrasted sharply with what we had seen firsthand with the original PrimerCube design. As a result, in June 2024, we publicly withdrew all support or endorsement of any product made by the company in the Czech Republic.
A New Direction—With Unexpected Help
After five years of keeping the PrimerCube open-source and watching the market fail to reproduce it faithfully, we were discouraged. We had poured years into the technology and made it freely available in good faith—but no one stepped up to manufacture it to proper standards.
Then, something unexpected happened.
Shortly after we withdrew our support of the Czech product and began posting notices on various forums (including Reddit), we were contacted by a Silicon Valley tech executive who had seen our earlier PrimerField videos that were focused on physics and astrophysics. He believed in the theories presented in those PrimerField videos and offered to fund our research efforts going forward.
What we really wanted—more than new research—was to get the original, proven PrimerCube design back into production exactly as we had built it before. This donor generously made a very large contribution to the PrimerField Foundation so we could pursue that goal.
We began sourcing components and building infrastructure in August 2024. However, over the following months, we ran into persistent manufacturing difficulties. Despite investing over $200,000, we were unable to replicate the original PrimerCube to the standard we required.
A New Design Emerges
What seemed like a major setback turned out to be something else entirely. That setback turned out to be a blessing in disguise.
In September 2024, inspired by ongoing research and supported by new funding, we began developing a new PrimerField magnetic array. This project ran in parallel with our continued work on the PrimerCube, with no clear expectation of where it might lead. When I first started designing the array that would become the PFE25™, we assumed it might simply complement the PrimerCube—used alongside it, not replace it. I had no idea it would evolve into something even better.
By early 2025, we had built and tested several of these new arrays. To our surprise, the results were consistent and impressive. Based on our internal evaluations and feedback from people familiar with earlier devices, we found this new array to be more effective than the original PrimerCube—and significantly easier and less expensive to produce.
We distributed early units to people who had used both the original PrimerCube and the modified Czech versions. The overwhelming response: this new array was equal to—or better than—the original PrimerCube, and clearly superior to the poor copy products on the market.
Given the ongoing challenges with manufacturing the original PrimerCube, we made the decision in March 2025 to stop pursuing its production and shift our full focus to this new array,
which we have named the PFE25™, as it is a PrimerField Emitter developed in 2025.

Introducing the PFE25™
The PFE25™ reflects everything we’ve learned—from the original PrimerCube, from failed attempts at open-source replication, and from the needs of users who value quality, consistency, and ease of use.
We’ve filed for patents to protect this new design. Unlike our earlier open-source model, the PFE25™ will be manufactured by a single, authorized U.S. company to ensure consistent quality and construction.
This decision isn’t about profit. It’s about control, accuracy, and safety. We want people to receive only the version we’ve tested and verified—made to the exact specifications that we’ve seen work again and again.
We are committed to never being involved with anything that could mislead or harm people. That includes never endorsing unauthorized versions of this technology or companies that alter the design for commercial gain.
Why You’ll See Changes on Our Website
You may notice we’ve removed our old technology transfer section and all prior open-source materials about the PrimerCube from our site. We have also removed all the information on the PrimerCube to avoid confusing anyone. Our focus is now 100% on the PFE25™, and making it available to people as quickly as possible.
This reflects our shift away from the open model. After five years, it became clear that the open-source route did not result in reliable, widespread access to high-quality PrimerField-based devices. Instead, it allowed altered versions to circulate—some of which we believe were ineffective. At one point, a French distributor—who was selling copies of the PrimerCube manufactured by the Czech company—openly encouraged his customers to email us with reports of positive results. Despite this public request, I did not receive a single message from any satisfied users. Instead, the emails continued to come from individuals who reported no noticeable effects from the Czech-made cubes—and who shared their frustration that the company had refused to issue refunds. This is why we’ve decided not to make the technology behind the PFE25™ open-source. We gave that approach a full five years, hoping it would lead to meaningful results—but in the end, it simply didn’t bear fruit.
Moving forward, the PrimerField Foundation is committed to:
Supporting a single, standardized production of the PFE25™
Providing clear, FDA-compliant information on how it is used
Maintaining the integrity and purpose of the work we started
We are currently finalizing a general use and placement guide for the PFE25™ and expect to make it available within the next two months. Around the same time, the authorized manufacturer will begin offering the PFE25™ for sale online.
