Solar water pumping

Solar Energy, 1978
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 ...

Conransporters as molecular water pumps

2002
Molecular water pumps are membrane proteins of the cotransport type in which a flux of water is coupled to substrate fluxes by a mechanism within the protein. Free energy can be exchanged between the fluxes. Accordingly, the flux of water may be relatively independent of the external water chemical potential and can even proceed uphill. In short, water

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.
