Solution Overview

Problem

Current methods for large-scale carbon capture face challenges such as high land requirements, significant costs in technology and energy, and inefficient use of resources, while existing carbon dioxide removal technologies often fail to address atmospheric CO2 directly and may not be cost-effective or sustainable.

Innovation Solution

Inoculation of tropospheric clouds with a specifically cultured psychrophilic microalgal species, known as the RubisCO Climate Vaccine (RCV), which utilizes low-cost technology to capture CO2 directly from the atmosphere, forming algal blooms that sequester carbon and release oxygen, leveraging natural processes for widespread carbon capture and deposition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional carbon capture methods are used, then CO2 removal capacity is achieved, but land requirements and opportunity costs increase significantly

Engineering Contradiction:
ImproveCO2 removal capacityVSAvoidland requirement
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The patent moves carbon capture from the ground level to the atmospheric dimension by inoculating tropospheric clouds with psychrophilic microalgae. This dimensional shift allows CO2 removal to occur in the air space above land rather than requiring dedicated land areas for capture facilities, effectively utilizing the three-dimensional atmospheric volume for carbon sequestration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The psychrophilic microalgae perform self-propagation and self-sustaining growth within the cloud environment, utilizing ambient CO2, water, and sunlight. The system captures carbon while simultaneously reproducing and maintaining itself without requiring external land-based infrastructure or continuous human intervention for operation and maintenance.

Inventive Principle:
Principle #25Self-service

2Productivity

If conventional carbon capture technologies are deployed, then CO2 removal is achieved, but technology and energy costs become tremendous

Engineering Contradiction:
ImproveCO2 removal capacityVSAvoidenergy cost
Core Design Contradiction:
ProductivityVSUse of energy by stationary object

Solution Approach 1:

The microalgae system is entirely self-powered through photosynthesis, converting sunlight directly into the energy needed for CO2 fixation and biomass growth. No external energy input, electrical systems, or mechanical components are required, eliminating the tremendous energy costs associated with conventional active carbon capture technologies.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces mechanical and electrical carbon capture systems with a biological photosynthetic system. Instead of using energy-intensive mechanical pumps, compressors, and chemical processing equipment, the system utilizes natural photosynthesis driven by sunlight, substituting complex mechanical infrastructure with a simple biological process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 1:

The psychrophilic microalgae serve as a biological intermediary that directly interfaces with atmospheric CO2 within cloud droplets. The algae cells absorb CO2 directly from the air phase through the cloud water interface, providing true direct atmospheric capture rather than indirect removal through combustion flue gases or other intermediate sources.

Inventive Principle:
Principle #24Intermediary (Mediator)

Function Achieved in This Case

The RCV method effectively reduces atmospheric CO2 levels by orders of magnitude, potentially reversing climate change to pre-industrial levels within a decade, while being cost-effective and environmentally beneficial, with the algal blooms contributing to the food chain and long-term carbon deposition.

Implementation Method 1

Photosynthesizing microorganisms within the clouds photosynthesize (convert CO2 to biomass) utilizing sunlight energy fixing the CO2 abundant in the troposphere into plant growth and replication. This process also releases valuable oxygen (O2) back into the atmosphere.

AI summary

The present invention comprises the deployment of a product known as RubisCO Climate Vaccine® or simply RCV which contains a specialised adapted culture of psychrophile algae and accelerators. This RCV is inoculated into targeted tropospheric clouds. The cumulatively large air-liquid optical interface area of clouds enables conditions for potential exponential photosynthetic algal growth and replication during which carbon dioxide is processed and oxygen released directly in the troposphere. Optimal inoculation sites are determined by altitude, humidity, temperature, weather patterns and predicted direction and duration of travel for precipitation, The biomass produced in this process is intended to be precipitated over mid-ocean where it is sequestered within natural ocean food chains or sedimented as detritus essentially permanently. This nature-based solution through repeated deployments offers a feasible scalable pathway toward potential climate change reversal within a decade with minimal or no adverse environmental impact.
