Digital Social Hour – Episode #1899: The Truth About Geopolymer Materials with Owen Benjamin & Chris Gardner
Date: March 31, 2026
Host: Sean Kelly
Guests: Owen Benjamin, Chris Gardner

Episode Overview

In this lively and wide-ranging episode, Sean Kelly welcomes Owen Benjamin (comedian, builder, “biochar snob”) and Chris Gardner (gardener, podcaster) for a deep dive into geopolymers, biochar, soil health, alternative history, and the oddities of conventional narratives about carbon, ancient civilizations, and technology. The trio blends practical insights on soil amendment with speculative and sometimes provocative takes on history, social engineering, and the mysteries of perceived reality. Expect a mix of practical gardening advice, irreverent humor, and bold challenges to mainstream science and history.

Key Discussion Points & Insights

1. Biochar: What It Is and Why It Matters

• Definition & Creation (00:46 – 02:32)
  • Owen introduces biochar as 'fixed carbon' made in an oxygenless environment—much more stable than regular charcoal (“stable for up to about 15,000 years”).
  • He elaborates on its difference: “Charcoal, they're usually doing pit burns where a lot of oxygen goes ahead and works on the carbon, and it creates a secondary oxidative stress. This is fixed because there was no oxygen in the burn.” (00:52)
  • Water Filtration & Diamonds: Biochar, at a micro level, contains what amounts to micro-diamonds, aiding in structuring and filtering water, resulting in bigger yields — “we’re getting between four and five times the yield” using it. (01:37)

2. Carbon: Demonization Versus Reality

• “We’re made out of carbon!” (03:05)
  • Chris observes, “...the demonizing of carbon, and we're made out of carbon, so it almost seems like that bad dad that is like, blaming everything on the kids...”
  • The guests push back against narratives blaming carbon for climate change, calling for more carbon in soil, not less. (04:12)

3. Soil Life & Amazonian Agriculture

• The Secret of the Amazon Rainforest (05:07 – 06:32)

  • Owen describes pre-Columbian Amazon as “more agriculturally intensive than Asia,” citing “terra preta” (rich black soil created by indigenous agriculture with biochar).
  • The process: chop-and-drop agriculture, covered kilns, and infusing carbon into soils led to the thriving Amazon—contrasted with the man-made desertification of the Sahara through deforestation for construction materials.

• Quote:

  “When the trees came back in, there was all this carbon in the ground. And then that's why the Amazonian rainforest is as massive as it is.” – Owen (06:14)

4. Ancient Construction & Geopolymers

• How Pyramids and Megastructures Were Really Built (06:52 – 15:37)

  • Instead of the “slaves and rollers” narrative, the team details Davidovitz’s theory: pyramids and ancient walls were cast in place as geopolymers, made from blended natural materials and minerals (volcanic/fly ash, natron, clay, and sand), not quarried stone blocks.
  • They note archaeological evidence, such as notches and spiral ramps inside pyramids and structures worldwide, support this construction method.
  • “...the geopolymers, they get harder over time. Same with Roman aqueducts.” – Christopher (09:56)

• Logistics & Architecture

  • Real-world building experience (Owen’s domes and Chris’s gardening structures) reveals the immense challenges of “moving heavy things on undeveloped land,” supporting the idea that ancient builders used lighter, cast materials on site (17:17).
  • “The last thing that you can do on a piece of land that has no roads is build something heavy.” – Owen (17:17)

5. Modern Applications & Technological Parallels

• Biochar in Modern Construction and EMF Shielding (18:58 – 20:13)

  • When mixed with concrete, biochar improves the medium and even blocks electromagnetic frequencies (EMF), including 5G:

    “We've literally been able to get the internals of rooms and buildings to zero [EMF]... Especially 5G won't [penetrate].” – Owen (19:31)

• Graphene & Cloud Seeding (20:30 – 21:56)

  • The team discusses graphene’s “villainization” and its dual use – as a superior conductor and as a reflective element in paints or dispersants (e.g. for weather/climate modification).
  • Owen advocates for precise legal terminology: “If you use the word cloud seeding and high atmospheric aerosol dispersant, then you could actually have legislation that would actually do something.” (21:44)

6. Data Centers, Geoengineering, and Land Devaluation

• Texas Floods and the Data Spine (22:56 – 25:48)
  • Large, engineered weather events are linked (speculatively) to clearing land for massive data centers: “They're devaluing the land by these controlled outbursts of rain or these controlled outbursts of fire in these very specific farm [areas]... Sell it to us, you know, pennies on the dollar.”
  • Chris and Owen note how deep-rooted native grasses prevent flooding and how loss of grasslands leads to water management issues. (26:04)

7. Savannahs, Grasslands, & Forest Management

• The benefits of grasslands and balanced tree management:
  • Burning native grasses (prescribed fire) fixes carbon and regenerates the landscape. (26:38)
  • Aggressive young tree removal benefits older trees and soil health:

    “They’re competing for the very limited nutrient base... You need 12ft in every direction. With no saplings.” – Owen (29:08)

8. Nature, Presence, and Vibrational Encounters

• The conversation turns philosophical:
  • Presence in Nature: Being calm and present draws wildlife closer; animals are sensitive to human energy (“if I just settle down and I'm just, like, present, then [the animals] are like, bro.”) (30:49)
  • Nature as a “healer” and a “no lies” zone. (32:51)

9. Alternative History: The US as the True “Holy Land”

• Bold Claims on Biblical Geography (34:36 – 39:20)
  • Owen floats the idea that the Western US is the real “Holy Land” of the Bible, the Redwoods are the “Cedars of Lebanon,” and Salt Lake is the Dead Sea:

    “I really think that the Holy Land was the western United States, actually where we are right now... that area fits that [biblical narrative] so much better.” – Owen (35:51)

  • “Florida was the Garden of Eden... only place in the world that grows gopher wood.” (38:43–39:14)

10. Narrative Inversions & Social Engineering

• Questioning Mainstream Narratives
  • The guests point out recurring societal inversions: blaming carbon, fat, or salt for health woes—while ancient wisdom and modern evidence suggest otherwise. (41:08)
  • They speculate about base-level social engineering that keeps people from seeing these “truths.” (42:06)

11. CERN, Vortexes, and Portals

• Speculative Physics and Reality (43:17 – 45:46)
  • Positioning CERN as a “gateway” built on ancient sacred ground (Mount Hermon), possibly creating “portals” or “vortexes” through particle collisions.

12. Mandela Effect and Nature of Reality

• Debating Objective vs. Infinite Realities (45:49 – 49:17)
  • The group shares examples of Mandela Effects (Curious George, C-3PO, Franco Colombo/u) and discusses whether reality is objective or if each person experiences a unique cut:

    “There is objective reality, and I think we're all trying to find... objective reality because each one of us, none of us are ever going to experience each other's realities.” – Owen (47:27)

13. Flow State, Identity & Ego

• Performance, Presence, and “The Zone” (49:32 – 52:07)
  • Athletic and artistic achievement demand ego, but flow state is “effortlessness”—the “being” overtakes the “doing.”
  • “When you’re operating at a high level, you do kind of disappear.” – Christopher (51:46)

14. Closing: Biochar Promotion & Further Resources (57:02 – 58:13)

• Owen plugs his company, Black Hole Biochar (“not charcoal!... we isolate the outside environment... we get the really good stuff with all the nano diamonds”), as well as his podcast, Biocharisma.
