Keng Choi, a material scientist at Shanghai Zhao Tong University and the study's senior author. In a media release, he acknowledges the challenges in developing a system that can automatically switch off and on without external energy. To combat that issue during winter, Dr. Choi's team employed an effect called the photon recycling. Essentially, any trapped energy under the cloak will oscillate between the vehicle and the cloak. Instead of dissipating into the surrounding environment. The cloak is designed to protect the electric automobile in all weathers
