Our technology is to match solar renewable energy with efficient phase change cooling. Our integrated technology will capture this energy from daylight and store it in the ground to maintain the desired latent temperature of the PCM material in a sub-layer below the "top layer". In addition, a full charge of "latent" cold from a 10 cm thick layer of PCM can keep the system cool for 2-3 days without sunlight. If excess electricity is produced, it can be sold back to the grid. We design the PCM container to help channel and store waste heat. The integration of the cooling tube network allows the temperature of the ice sheet to be "adjusted" to achieve the appropriate cooling effect.
