A new sturdy, flexible and low-cost metamaterial can ‘self-cool’ without water or electricity, in buildings, satellites, power plants or military tents under the desert sun. The U.S. Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) has awarded PARC, a Xerox company, $1 million to develop this technology and prove its scalability.
Exceeding the performance of any competing product, the passive radiative cooling system can cool to 6° C below ambient temperatures when facing the sun. It’s ‘a real technical feat and a game-changer for dry cooling applications’, says Bernard Casse, area manager of PARC’s metamaterial devices and applications group. The technology can also be tiled over large areas in multiple radiative cooling panels, similar to solar farms.
‘This material has the potential to enhance the way we meet customer needs for the most effective cooling solutions,’ adds Eric Rasmussen, director of global research and development at SPX Cooling Technologies, Inc. SPX – global leader in ‘full-line, full-service tower and air-cooled condenser manufactur[ing]’ – will be working with PARC.
