Promethean Power originally envisioned building a milk chiller that ran with the aid of solar panels to create a less polluting system. After many trials and tests in the field, it found that the solar system was too expensive for India. However, the system can still operate in conjunction with solar panels. These are the panels they use for testing at Promethean Power's work space at clean tech incubator Greentown labs in South Boston.
