Cuticular Water Pump in Insects

Nature, 1967
AMONG the ways in which terrestrial arthropods can control their environmental water relations, the active retention of water1, the regulation of water loss2, and the active uptake of atmospheric water3 have been found to be concerned with the movement of water through the cuticle.

Molecular water pumps

2008
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 water pumping

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.

Water Jet Pump

Journal of the Hydraulics Division, 1964
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.

WATER PUMP CONTROLLER

International Scientific Journal of Engineering and Management
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.
