Clean water through appropriate technology transfer

The successful development of heat pump assisted water purification systems in Mexico has resulted from more than two decades of international co-oper ation in heat pump technology. The basis of this international technology t ransfer has been the development of postgraduate degree programmes initiall y with India and later with Mexico. An overall objective of these programme s was to match energy supply more appropriately with end use energy needs i n order to minimise the unnecessary degradation of high grade energy source s. A further objective of the programmes was to retain high grade technical personnel in their own countries. (C) 2000 Elsevier Science Ltd. All right s reserved.
