Scientists brew energy-efficient espresso. It is made without heat and 75% less energy.
Scientists have developed a method to produce espresso using ultrasonic sound waves instead of heat, reducing energy use by 75%. The process uses room temperature water and creates espresso that taste-testers found indistinguishable from conventional brews. This innovation could significantly lower the energy consumption associated with coffee production.
