Living Off-grid

Infrastructure is fascinating, atleast to me. Recently I have been reading up about the infrastructure required for research at The South Pole. A lot of the things which we take for granted while we carry out our daily lives are not readily available there. The average annual temperature is around -49°C which means that water in liquid form is not available. What they have to do instead is pump heated water to a structure which is called Rodwell which forms an underground lake of water, heated water is continuously pumped to this through insulated pipes to ensure that it does not freeze.
