Problem
Traditional cooling methods, such as those used in thermoelectric power plants and building HVAC systems, often consume significant amounts of energy and water, contributing to environmental concerns and resource depletion. Existing dry-cooling systems, which reduce water consumption, suffer from high costs and low efficiency, limiting their widespread adoption.
Solution
Radi-Cool develops passive radiative cooling metamaterials that dissipate heat without requiring external power or water input. The core technology utilizes a hybrid glass microsphere-plastic film that reflects solar energy and emits infrared radiation, enabling cooling even under direct sunlight. This metamaterial film can be manufactured at scale using roll-to-roll processes and applied to various surfaces, including building envelopes, transportation vehicles, and solar cells, to reduce energy consumption and improve efficiency. By integrating this technology, industries can achieve sustainable cooling solutions while minimizing environmental impact.
Target Audience
The primary target audience includes thermoelectric power plants seeking supplementary cooling solutions, building owners aiming to reduce HVAC energy consumption, manufacturers of transportation vehicles, and the agriculture industry looking for sustainable cooling methods for greenhouses.
