Solution Overview
Problem
Current solutions for climate change are either too costly or take a long time to show effects, necessitating a cost-effective, short-term measure to mitigate acute warming conditions.
Innovation Solution
A high-altitude balloon system is deployed at a set orbital location in the path of solar radiation, featuring a reflective surface to reflect solar radiation away from Earth, utilizing a multilayer coating and thrusters for stability, and can be sustained for decades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current climate change solutions are implemented, then carbon dioxide levels are reduced, but the implementation time is too long and costs are too high for short-term warming mitigation
Solution Approach 1:
The patent segments the climate mitigation approach into two distinct components: long-term carbon dioxide reduction strategies and short-term solar radiation management. The balloon system specifically addresses the short-term component by reflecting solar radiation before it reaches Earth, allowing immediate climate intervention independent of lengthy carbon reduction processes
Solution Approach 2:
The patent introduces an intermediary system (balloons with reflective surfaces) positioned in space between the sun and Earth. This intermediary reflects a portion of solar radiation away from Earth, providing immediate climate cooling effect without requiring changes to atmospheric carbon dioxide levels or long-term behavioral changes
2Reliability
If current climate change solutions are implemented, then carbon dioxide production is reduced, but the cost is too high for stopgap measures
Solution Approach 1:
The patent employs disposable balloons with reflective surfaces that can be launched into orbit and left to perform their function. These balloons are relatively inexpensive compared to long-term carbon capture infrastructure, and their temporary nature (lasting months to years) is sufficient for stopgap climate mitigation. After deployment, they provide immediate solar radiation reflection without requiring recovery or maintenance
Solution Approach 2:
The patent extracts the climate mitigation function from Earth-based systems and places it in space. By positioning reflective balloons in orbit or upper atmosphere, the system removes the need for costly and complex terrestrial infrastructure required for carbon capture and storage, achieving climate cooling through a simpler, more cost-effective space-based approach

Function Achieved in This Case
The balloon system effectively reduces solar radiation reaching Earth, providing a rapid and sustainable solution for short-term warming mitigation while being capable of long-term deployment, with measurable climate responses.
Implementation Method 1
at least one high-altitude balloon having an outer surface at least partially defined by material configured to reflect solar radiation
Data Source
AI summary
The present disclosure provides a balloon system for mitigating solar radiation. The balloon system reflects solar radiation away from the earth. The balloon system includes at least one balloon having an outer surface for reflecting solar radiation. An orbital launching system launches the balloon to a set orbital location at which the balloon can orbit around earth in a path of solar radiation from the sun toward earth. At the set orbital location, the earth's gravitational force and solar pressure imparted on the balloon counterbalance the sun's gravitational force on the balloon. The set orbital location is spaced apart from a Lagrange stability point L1 in a direction toward the sun and away from the earth.
