Promethean Power has developed a novel energy storage system that uses a cold liquid to rapidly chill milk even when there's no power from the grid available. The company's first three cold storage systems will be deployed in India this year at processing centers. By having these types of systems, milk collection points can take milk from small farmers for longer hours, thereby giving them more opportunity to earn money. Seen here is a test system using water at Promethean Power's South Boston workspace at Greentown Labs, a clean-tech incubator. The warm milk, brought directly after milking, is poured over the cylinder-shaped tank and quickly brings milk to 4 degrees Celsius.
