OzonePhi — Reverse Calvin Cycle Purifier

The world's first dual-purpose air-and-water purifier, from a $299 bedside unit to a $5M municipal water plant. Same patented core, every scale.

OzonePhi combines two distinct scientific processes that work synergistically. The reverse Calvin Cycle uses catalytic chambers to break CO₂ and dissolved organics into solid carbon plus clean O₂. The Cu/Al electrochemical oxidation system generates controlled ozone (3,000× chlorine for resistant pathogens) that decomposes to clean O₂ with zero residue. Both systems share the same enclosure, the same controller, and the same patent foundation. Acquired in four named configurations from $299 home air to a $5M municipal water plant.

Headline Performance

Two Breakthrough Technologies, One System

OzonePhi is the only product in the AutoPhi Environmental Series that does air and water purification from one enclosure. That's because two distinct scientific processes share the catalytic chamber, the FPGA controller, and the patent foundation.

System A — Reverse Calvin Cycle (Catalytic Carbon Breakdown). In nature, the Calvin Cycle fixes CO₂ into sugar using sunlight. OzonePhi reverses this electrochemically — using copper-electrode catalytic chambers to drive the breakdown pathway in the opposite direction:

CO₂ + Catalyst + Energy → C (solid) + O₂ (clean)

Contaminated air or water enters the catalytic chamber; reverse-carbon-fixation catalysts bind to CO₂ and dissolved organics; LED-recycle energy input (Patent 3561/2876) drives the breakdown; carbon precipitates as stable solid for industrial reuse; clean O₂ is released. The same pathway processes airborne CO₂ and dissolved CO₂ — air and water are interchangeable inputs. Catalysts are regenerated and the cycle repeats continuously. Published proof: Bui et al., ACS Energy Letters (2023).

System B — Cu/Al Electrochemical Ozone Generation. When current flows through copper and aluminium electrodes in water or humid air, the anode reaction generates ozone:

3H₂O → O₃ + 6H⁺ + 6e⁻ (E° = +1.51 V)

Patents 1096-1098's electromagnetic-field control modulates the electrochemical double layer to bias the reaction toward O₃ over the competing oxygen-evolution pathway. Ozone (oxidation potential +2.07 V) destroys Cryptosporidium at 7,200× lower dose than chlorine, leaves zero chemical residue, and decomposes back to O₂ with a 15–30 minute half-life in water at 20°C. Published proof: von Gunten, Water Research 37 (2003): 1443–1467.

Integrated Air & Water Purification Cycle

Both air and water pass through the same core technology stack, with mode-specific adjustments for ozone concentration and flow dynamics:

1. Intake & Sensing. Smart sensors detect contamination type and level, auto-selecting air-mode (VOC, CO₂, PM, pathogen sensors) or water-mode (TDS, pH, dissolved O₂, pathogen sensors); processing intensity auto-adjusts.
2. Reverse Calvin Cycle. Catalytic chambers break down CO₂ and organic carbon into solid carbon plus clean O₂. LED-recycle system (Patent 3561/2876) powers the catalytic reaction; solid carbon collected for disposal/reuse.
3. Ozone Generation. Cu/Al oxidation produces controlled ozone for disinfection. EM-field control (Patents 1096-1098) sets oxidation rate precisely; air mode uses low ozone (<0.05 ppm, FDA-compliant for indoor occupied spaces); water mode uses high ozone for deep disinfection.
4. Purification & Kill. Ozone destroys 99.99% of bacteria and viruses on contact, destroys mould, allergens, and odours, and breaks down pharmaceutical residues in water.
5. Clean Output. Ozone decomposes to O₂ naturally; output is purified, oxygen-enriched air or water; continuous quality monitoring confirms it.

Ozone Safety — Five Independent Layers

Ozone is toxic at high concentrations. OzonePhi has five independent safety layers, all stated honestly in the package:

• Continuous electrochemical sensor (0–1 ppm range, ±0.01 ppm) for real-time monitoring.
• FPGA auto-shutdown kills the electrodes if measured ozone exceeds 0.04 ppm in occupied mode — below the FDA 0.05 ppm consumer limit.
• MnO₂ destructor cartridge on the outlet catalytically decomposes residual ozone (2O₃ → 3O₂).
• Occupied / unoccupied mode with motion-sensor interlock automatically lowers ozone when the room is in use, raises it when empty.
• Audible alarm at 0.08 ppm as a final failsafe warning.

OSHA workplace limit: 0.1 ppm (8-hr TWA). FDA consumer limit: 0.05 ppm. UL 867 requires <0.05 ppm. OzonePhi operates at <0.04 ppm in occupied mode.

Applications — Eight Markets, One Core

Four OzonePhi Configurations

OzonePhi vs Traditional Air & Water Purification

Patent-Protected Core

OzonePhi is built on Christopher G. Brown's existing patent portfolio, with a filed USPTO application as the core IP anchor.

Market Context — Four Markets, One Product

OzonePhi reaches four distinct markets simultaneously through its dual air-and-water capability:

• Home air purifier market — projected to reach $80B+ by 2030.
• Point-of-use water purifier market — $45B+.
• Healthcare air-quality market — $15B+.
• Industrial ozone generation market — $12B+.

Underlying scale: 4.2 million deaths per year globally from air pollution (WHO), and 2 billion+ people without safe drinking water. OzonePhi is the only product in its class that addresses both with one technology.

How it's made

OzonePhi is the productised assembly of two distinct scientific processes — reverse Calvin Cycle catalytic CO₂ breakdown and Cu/Al electrochemical ozone generation — sharing one enclosure, one FPGA controller, and one patent foundation. The catalytic chamber and the electrochemical cell are co-located so the same intake-and-sensing front-end serves both, and so the system can switch fluidly between air mode and water mode based on what's been put in the input. The package contains the full engineering specification (deep-3-ozonephi-engineering.md) covering electrochemistry, safety architecture, and consumer BOM, plus the staircase mirror chip companion document (deep-10-staircase-mirror-chip.md) describing the multi-bandgap photon cascade that powers the LED-recycle stage at higher generations of the product.

Why I made it

Chlorine has been the world's default water disinfectant for over a century, and HEPA has been the default air-particulate solution for nearly as long. Both work; neither is good. Chlorine produces trihalomethanes and haloacetic acids — both flagged as carcinogenic disinfection byproducts — and is 7,200× less effective than ozone against Cryptosporidium. HEPA traps but does not kill, requires expensive replacement on a six-to-twelve-month cycle, and ignores the gases (VOCs, CO₂, NO_x) that the worst air pollution actually consists of.

I built OzonePhi because the science of ozone disinfection and the science of catalytic CO₂ reduction are independently mature and, when combined in one enclosure with the right safety architecture, address both legacy gaps from one product. The four-configuration ladder — Home Air, Home Dual, Commercial, Industrial — reaches consumers at $299 and reaches municipalities at $5M with the same patented core. That ladder is what makes the product competitive in markets that have, up to now, been served by separate vendors with separate technologies and separate failure modes.

What it can do

Across the four configurations, the same dual-system core handles every scale from a $299 bedside air purifier through a $799–$1,499 home air-and-water flagship through $5K–$50K commercial HVAC-integrated systems up to $100K–$5M municipal water plants that replace chlorination entirely. Performance is consistent across configurations: 99.99% pathogen kill, 3,000× chlorine disinfection power, zero filter replacements, zero chemical residue, <35 dB operation, <0.05 ppm indoor ozone (FDA-compliant), and 10+ year electrode life.

What the system does not do: it does not generate net electricity (it consumes a small amount — 15W for a consumer unit), it is not a refrigeration or HVAC product (it integrates with HVAC but doesn't replace it), and it is not a CO₂ climate-scale carbon-capture solution (the per-unit CO₂ capture is meaningful at the household level but not at the atmospheric level — that's AtmoPhi's domain).

Why it's a fact

Every claim above can be checked against the source record:

• Both core sciences are grounded in named, dated, peer-reviewed publications — Bui et al. (ACS Energy Letters 2023) for electrochemical CO₂ reduction, von Gunten (Water Research 2003) for ozonation chemistry. Each paper is independently retrievable.
• The five-stage integrated cycle and two-system science are documented in deep-3-ozonephi-engineering.md at the electrochemistry-and-safety level and in product-3-ozonephi.html at the marketing level. Both ship with the package.
• The five inventor patent references (3561/2876, 1025, 1026, 1096-1098, 1204) are catalog/book references in the inventor's filing record per PATENT_PORTFOLIO.md — internal book numbering, not USPTO publication numbers.
• USPTO 18/650,137 was filed April 2024 and is on file at the USPTO. Status verifiable at patentcenter.uspto.gov. Per PATENT_LINKAGE_REPORT.md, this application has 16 mentions in the project 34 documentation, more than any other recent USPTO entry for this project.
• The five safety layers (electrochemical sensor, FPGA auto-shutdown, MnO₂ destructor cartridge, occupied/unoccupied mode, audible alarm) and their thresholds (<0.04 ppm occupied operation, 0.04 ppm shutdown, 0.05 ppm FDA limit, 0.08 ppm alarm) are stated explicitly in the package's INDEX and engineering spec.
• The four configurations with capacity bands and price ranges are itemised in the brochure's "Four OzonePhi Configurations" section.
• The eight applications and the side-by-side comparison against HEPA and chlorine are itemised in the brochure's "Applications" and "OzonePhi vs Existing Technology" sections respectively.

License Terms — What's Granted, What Isn't

The acquisition grants the buyer permission to make, build, and copy the deliverable. It does not transfer the underlying intellectual property:

• Granted with the acquisition: permission to manufacture (or have manufactured) the OzonePhi system at any of its four configurations (Home Air, Home Dual, Commercial, Industrial); permission to build deployments at consumer, building, or municipal scale; permission to make copies of the blueprint package for the buyer's engineering, manufacturing, and regulatory use.
• Not transferred with the acquisition: USPTO 18/650,137 (Filed 04/2024, extended IP coverage), the inventor's portfolio book references (3561/2876, 1025, 1026, 1096-1098, 1204), trademarks (OzonePhi), copyrights, or any rights to license or assign the IP onward. The intellectual property remains held by Christopher Gabriel Brown.
• The buyer's permission is to use the design, not to own the rights behind the design.

This framing applies uniformly across the inventor's portfolio. Buyers seeking IP assignment rather than make/build/copy permission should contact the inventor directly — that is a separate negotiation outside the standard storefront acquisition.

Two scientific processes, one enclosure, four configurations, one filed USPTO application. From $299 to $5M.

A buyer who acquires OzonePhi takes possession of the blueprint package — the design content for a dual-purpose air-and-water purification system anchored to USPTO 18/650,137. The blueprint scales from consumer to municipal. Patent coverage flows through five entries in the inventor's existing portfolio plus the filed USPTO application.
