The Southern Ocean, rich in nutrients but iron-deficient, experiences increased phytoplankton blooms due to whale feces, acting as a significant carbon sink. The phenomenon of whales defecating near the water's surface reverses the typical flow of nutrients in the ocean's biological pump, contributing to the "whale pump." Whales feed at deeper ...

This inspired the use of closed circuit hot water systems for large buildings. A metal furnace in the basement burning wood or coal was used to heat water in a tank, which in turn was circulated by an electric pump through a system of iron pipes throughout the building to radiators in rooms where heat was lost to the ambient air.
