WebbHeat-pipe Earth. A hypothesis has been introduced to the early Earth that the Earth followed heat-pipe tectonics theory and cooled down through volcanism. From 4.5 billion years ago, the earth started cooling until 3.2 billion years ago when plate tectonics started.

A heat pipe is a heat-transfer device that employs phase transition to transfer heat between two solid interfaces. At the hot interface of a heat pipe, a volatile liquid in contact with a thermally conductive solid surface turns into a vapor by absorbing heat from that surface. The vapor then travels along the heat pipe to … Visa mer A typical heat pipe consists of a sealed pipe or tube made of a material that is compatible with the working fluid such as copper for water heat pipes, or aluminium for ammonia heat pipes. Typically, a vacuum pump is … Visa mer The general principle of heat pipes using gravity, commonly classified as two phase thermosiphons, dates back to the steam age and Angier March Perkins and his son Loftus Perkins and … Visa mer Heat pipes must be tuned to particular cooling conditions. The choice of pipe material, size, and coolant all have an effect on the optimal temperatures at which heat pipes work.
