A clear new material could make windows super efficient

University of Colorado Boulder physicists have created MOCHI, a transparent silicone-based gel that could revolutionize window insulation by dramatically reducing building energy waste. The material uses microscopic air-filled pores that block heat transfer while allowing nearly all light to pass through, solving the longstanding challenge of creating effective window insulation without obstructing views. Buildings currently account for 40% of global energy consumption, much lost through inefficient windows. Though still in laboratory development, MOCHI shows promise for widespread energy-saving applications.
