Abstract The principles of solar water pumping are briefly described. The mechanical energy needed for pumping water may be produced by thermodynamic, or direct-conversion methods. In thermodynamic conversion a fluid with high internal energy is produced in solar collectors or concentrators. The internal energy of the fluid may be utilized in Rankine-

Development for Stamped WATER PUMP (Innovative Structure WATER PUMP)
SAE Technical Paper Series, 2006<div class="htmlview paragraph">Requirements for weight reduction, downsizing and cost reduction have been increasing on automobile components. The same can be said for water pumps. However, significant weight reduction, downsizing and cost reduction have been big issues with conventional structure water pumps because these issues had been ...

There is good evidence that cotransporters of the symport type behave as molecular water pumps, in which a water flux is coupled to the substrate fluxes. The free energy stored in the substrate gradients is utilized, by a mechanism within the protein, for the transport of water.

Solar Energy, 1959
Abstract The left-way cyclic process, introduced in the preceding paper, is described for obtaining water out of air. Two working methods are utilized. The first one delivers drinking water out of air without any service, maintenance, etc. The second method requires opening a cover above the absorbent during the evening.

The water jet pump, when designed with experimentally obtained optimum dimensions, can achieve efficiencies in the range of 35% to 40%. The design depends on the selected nozzles and diffuser, as well as the other parts of the pump, so that the hydraulic losses incurred are kept to a minimum.

The Water ATM system is a practical solution to provide water to individuals in a controlled and automated manner. Using an Arduino-based platform, this system incorporates an RFID reader (EM18) for user identification and an LCD display (20x4) to show essential details such as remaining balance, the status of the transaction, and time remaining.
