Penn State researchers have engineered a groundbreaking passive cooling solution using porous PMMA sheets that reflect sunlight and significantly lower temperatures without electricity, achieving remarkable results in temperature reduction and energy efficiency. In a 2025 study, Penn State researchers tested porous PMMA sheets that reflected 96.4% of sunlight; a test box stayed 14.7°F cooler than the outdoor air.
