20120298328 | METHODS AND APPARATUS FOR TRANSFERRING THERMAL ENERGY - Municipal waste water systems can be a significant renewable alternative energy source for heating and cooling of buildings. Waste water flow rate and temperature data is collected over a period of time and locations within the waste water system that can act as a thermal energy source or sink are identified. Candidate buildings proximate the locations are identified. Thermal energy transfer apparatus can be used to transfer energy between an identified location and building. | 11-29-2012 |
