The Solex water pump is a refillable implosive Heron’s ball that makes the technical basis of thermodynamic machines visible in the form of a solar thermal steam pump. Its basis is:
Using the principle of Heron’s ball, the pump forces water upwards, where it is collected. This is the lift; the water in the upper basin is potential energy. When the water flows downwards, it is kinetic energy. In this way, the principle of the basic equation for heat engines (above) and the equivalence between heat and work becomes visible.
This Solex pump was developed as part of the Global Villages project (beginning with the Aldeas Global Populares in Peru, then in the Global Village of Kirchbach in Steiermark, Austria then in Thailand), and most recently as part of the Sustainicum project in Vienna. Global Villages, which are based on the concept of the European Broadband Initiative, promote regional development through education. However, they must be able to manifest tangible results that also involve the people living in the villages. Therefore, apart from the required valves, the Solex pump cannot have any moving parts, such as electric motors, photovoltaic panels, pistons, or gaskets; nor can it require lubricant, etc., as these are all things that the “village blacksmith” cannot readily maintain or repair. In addition, the chain of value creation must remain within the region.
Therefore, the logic of the Peruvian program to rebuild the agricultural technology of the Incas for the mining population in the Andes, which - unlike European mountain farmers - cannot be subsidized, was employed in order to revive the cultural heritage of Europe dating from the Alexandrian Hellenistic age. See the document “Origins of the Technology” (“Ursprung der Technik”) as an illustration of this.
Often, people are forced to implement acquired knowledge as soon as possible: in extreme cases, they try out innovative, sustainable technologies on their own, or have no electricity or even water for irrigation. In such instances, accessible, web-based feasibility is enormously important. See "Wikilampao Nanosolex".
