Solution Overview

Problem

Current methods for reducing global temperatures, such as greenhouse gas mitigation and carbon dioxide reduction, face challenges in effectively addressing rising temperatures and potential positive feedbacks from polar ice shelf loss, with existing solar radiation management techniques being costly, impractical, or environmentally adverse.

Innovation Solution

Deployment of floating mirrors on ocean surfaces near the equator, designed to reflect a small portion of solar radiation back into space, utilizing a buoyant body with reflective material and self-homing capabilities to maintain position and maximize albedo, thereby countering global temperature increases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If space deflectors and reflectors are deployed to manage solar radiation, then solar radiation management is achieved, but deployment cost is very high and retrieval is difficult

Engineering Contradiction:

Improveglobal temperatureVSAvoiddeployment cost

Core Design Contradiction:

TemperatureVSEase of manufacture

Solution Approach 1:

The patent employs numerous inexpensive floating mirrors made from simple buoyant bodies with reflective coatings instead of expensive space-based reflectors. These mirrors can be easily manufactured and deployed at low cost, sacrificing individual mirror longevity for overall system affordability and ease of replacement

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention transitions from three-dimensional space-based reflectors to two-dimensional surface-floating mirrors on ocean waters. This dimensional shift from space to sea surface dramatically reduces deployment complexity and cost while maintaining solar radiation management functionality

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Temperature

If cloud creation and aerosol deployment are used for solar radiation management, then temperature control is achieved, but constant replenishment is required which is energy costly and environmentally adverse

Engineering Contradiction:

Improveglobal temperatureVSAvoidenergy cost

Core Design Contradiction:

TemperatureVSUse of energy by moving object

Solution Approach 1:

The floating mirrors utilize natural ocean currents and wave action for positioning and movement instead of requiring active propulsion systems. The mirrors passively float and self-adjust their positions through environmental forces, eliminating the need for energy-consuming replenishment mechanisms

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The mirrors leverage buoyancy as a counterweight force to overcome gravity, allowing them to float on water surfaces without requiring energy-intensive support structures. This passive flotation eliminates continuous energy input needed for traditional aerosol deployment systems

Inventive Principle:

Principle #8Anti-weight (Counterweight)

3Temperature

If polar ice shelf albedo is reduced due to ice loss, then solar radiation penetration increases by 3 W/M2, but this accelerates global warming through positive feedback

Engineering Contradiction:

Improveglobal temperatureVSAvoidpositive feedback effect

Core Design Contradiction:

TemperatureVSObject-generated harmful factors

Solution Approach 1:

The floating mirrors are deployed in advance to counteract the albedo reduction effect before it can fully accelerate global warming. By preemptively reflecting solar radiation back to space, the system offsets the harmful feedback loop created by ice shelf loss

Inventive Principle:

Principle #9Preliminary anti-action

Solution Approach 2:

The invention converts the harmful effect of reduced polar albedo into a beneficial outcome by deploying artificial mirrors in equatorial regions. These mirrors compensate for the lost reflectivity elsewhere, transforming the climate crisis into an opportunity for engineered climate management

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)
