Solar Air Heaters 101 HowStuffWorks

During the day, excess heat is transferred to the heat sink for storage; when the sun goes down, heated air is transferred from storage to your house. Although a heat sink might extend your use of solar thermal energy into the night, incorporating one into a retrofit heating system is expensive. It can also be hazardous to your health.Solar Greenhouse Heat SinkThis cool air would then sink and flow through each looped hose, where it (theoretically) collects warmth from the soil heat sink, or "brick" as you put it. The heated air then rises through the central chimney, is circulated throughout the greenhouse and drops to the floor when cooled, to repeat the process.Solar Heat Sink for batch DistillationSOLAR HEAT SINK FOR BATCH DISTILLATION Project Opportunity Adam Leibert, Jamie Skeie, Matthew Pesicka, Thomas Viggiano Whey is a waste product produced during cheese making processes.
