A 21-year-old metro Atlanta inventor, Julian Brown, has become the center of global attention after cryptic social media posts and concerns about his disappearance. Celebrated for creating Plastoline, a novel machine that converts plastic waste into fuel, Brown has not posted or been seen publicly since early July. While his family has stated he is safe, the online speculation, unanswered questions, and mystery surrounding his final messages continue to fuel widespread concern.
Who Is Julian Brown?
Julian Brown is a young energy innovator and social media influencer, known under the handle “naturejab_,” with over 1.3 million Instagram followers and millions more on TikTok. Brown engineered Plastoline, a microwave pyrolysis reactor designed to transform plastic waste into gasoline, diesel or jet fuel. He began developing the technology in high school and ran experiments from a garage-turned-backyard lab.
What Is Plastoline and Why It Matters
Plastoline is a homemade device that uses microwave pyrolysis—heating plastic material in a sealed environment—to convert it into usable fuel. While similar processes exist, Brown emphasized his reactor’s portability, efficiency, and lower emissions compared to traditional methods. His invention gained popularity for addressing plastic pollution and offering a cleaner energy alternative.
The Disappearance Timeline
| Date | Event |
|---|---|
| July 9, 2025 | Brown posts a final video saying, “Something is happening… keep me in your prayers. I don’t know.” He warns he is “certainly under attack.” |
| July 10–27 | No posts on Instagram or TikTok; fans grow concerned upon noticing the silence. |
| July 28, 2025 | Reports about his disappearance go viral on social media. Fans speculate about hidden dangers linked to his invention. |
| July 29, 2025 | Brown’s mother, Nia Brown, confirms he is safe but refuses to reveal his whereabouts citing security concerns. Atlanta PD says no official case is filed. |
Julian’s last video hinted at being surveilled, referencing black helicopters and saying, “I don’t have long to live.” These remarks fueled speculation that powerful industry players might have targeted him due to the disruptive nature of Plastoline.
Speculations, Fears & Public Response
Online supporters have speculated that Brown may have been intentionally hidden for his own protection or even silenced by corporate or government entities threatened by his fuel-making technology. Posts citing leaked accounts of surveillance and private messages added to the mystery, although none has been verified. His disappearance triggered trending hashtags, online petitions, and pleas to law enforcement agencies to investigate.
Despite the frenzy, Brown’s mother and authorities have emphasized that no missing person case has been registered. The Atlanta Police Department confirmed they have no active investigation, and his mother simply said he is safe and that further details would jeopardize his security.
Julian Brown: His Innovation Journey
Julian founded NatureJab and raised funds via a GoFundMe campaign seeking $1 million to scale Plastoline with a full-scale reactor. Reportedly, he collected just over $18,200. His work earned media attention in platforms like Forbes, Canvas Rebel, and regional outlets highlighting his goal of addressing global plastic waste through sustainable technology.
In 2024, an experiment gone wrong resulted in second-degree burns, further emphasizing the dangers he faced as a solo inventor working without institutional lab support.
His vision: transform plastics into clean fuel to reduce landfill waste and contribute to energy independence, driven by frustration over ineffective recycling efforts.
Sorting Facts from Rumor: What’s Confirmed So Far
Confirmed information:
- Julian successfully developed Plastoline.
- He stopped posting publicly on or around July 9, 2025.
- His final videos contained vague warnings about potential threats.
- His mother confirmed he is safe.
- Police confirm no missing person case has been filed.
Unverified or speculative information:

Community Reactions & Social Media Momentum
Online platforms remain divided. Some fans urge caution and commend his work, believing he might be in hiding for personal safety. Others call for transparency and clarity. Despite speculation, no credible law enforcement updates have surfaced.
Some self-proclaimed witnesses claim to have seen messages from anonymous online accounts suggesting Brown lost access to his social media or had taken refuge. These remain unverified claims.
Why This Story Resonates Globally—and What It Means
Brown’s work addresses two global challenges: plastic pollution and alternative energy innovation. As a young Black inventor in the U.S., his narrative rings powerful in a broader context of underrepresented innovators pursuing radical solutions.
His sudden silence and mysterious posts reflect a recurring theme: the vulnerabilities of independent creators without institutional protection. They spark debate on how society supports pioneering minds from marginalized backgrounds.
What’s Next: Questions That Need Answers
Investigation remains clouded by limited confirmed data. Key questions include:
- Why has Brown remained out of public view?
- Will he or his family release clarification?
- Did any formal agency intervene or open an inquiry?
- Will Plastoline’s development resume now that attention has peaked?
Until more emerges, public curiosity and concern continue—but official updates from family or authorities remain scarce.
