RACHEL CRANE (CNN CORRESPONDENT): Air conditioning accounts for 10 percent of all global electricity consumption and the demand for this type of cooling is expected to triple by 2050, which could strain already overworked electric grids.

ELI GOLDSTEIN (CEO OF SKYCOOL): As it gets hotter, air conditioners, refrigeration systems need more energy to run. The more electricity we use for cooling, the more challenging it is to operate and provide electricity reliably.

RACHEL CRANE: That’s why it’s the company SkyCool’s mission to make existing cooling systems run more efficiently by taking advantage of a phenomenon that exists in nature. All objects give off heat in the form of invisible infrared radiation. As heat leaves an object, it becomes cooler a process known as radiative cooling. But some objects can actually become colder than the air surrounding it. It’s part of a reason frost forms on grass even if the air temperature is above freezing, but this only happens at night. Once the sun rises, the grass eventually warms back up. So SkyKool designed a new material with radiative cooling properties that work 24 hours a day.

ELI GOLDSTEIN: The radiative cooling... in the sense that we’re doing has really never been out there before. The effect is never observed during the day, and by enabling it with these films that we’ve developed you can now use this type of cooling even when it's under direct sunlight.
RACHEL CRANE: Developed using modern nanotechnology, the film has hundreds of tiny optical layers designed to emit the specific wavelength of radiation that maximizes cooling. But it’s also highly reflective, absorbing little energy so it stays cool even under the sun.
