Systems for decreasing local temperature using high albedo materials

Abstract

A system comprises a plurality of albedo-increasing materials distributed on a surface of a man-made structure and having an albedo that is greater than an albedo of the surface of the man-made structure, wherein the albedo of the albedo-increasing materials is at least 0.15. The plurality of albedo-increasing materials are positioned and sized to increase an evaporation rate at the surface for a given temperature and decrease a temperature characterizing the man-made structure.

AI Technical Summary

Benefits of technology

[0013]This invention provides systems and methods of environmental modification with climate control materials and coverings by causing a local adjustment of two parameters that may affect the local climate. The invention may affect (1) the absorption and / or reflection of incident solar energy (albedo), and (2) the rate and amount of evaporation of water. The invention may also contain buoyancy or added floating features, which may aid in the invention's effectiveness. The invention may also be designed to minimize ecological harm. It may also enhance ice nucleation, provide habitat and breeding ground, and intentionally provide open pore-like areas to enhance cooling by evaporative heat transfer.

[0016]There may be various methods of manufacturing or assembling the climate control materials. These methods may provide efficient or cost-saving means of producing the climate control materials.

Problems solved by technology

These proposals and others like them are likely an important part of the long-term solution to reducing a man-made increase in CO2, but they could take decades to implement widely, and there are substantial technological, sociological, political and economic hurdles to be overcome before widespread adoption is likely to occur.

Some difficulties with the methods listed above include their cost, irreversibility (for instance, if the solution overcorrects), the massive public works nature of the solutions, unintended weapons potential, and possible severe secondary problems (such as acid rain or health effects from added atmospheric sulfur compounds).

Some negative effects of these proposals may include uncontrolled change in oceanic evaporation rate and change to the local ecosystem, ecological effects (such as a change in the plankton species selection), and unintended reverses of the solutions (such as sudden release of CO2 from sequestration schemes).
