STANDARD SMALL TURBINES AN ECONOMICAL WAY OF HARNESSING MINOR WATER RESOURCES

Comparison of bauxite resources – geo-economical considerations

In order to meet the significantly increased metal demand of the world market, it has been decided to expand the capacity of the existing alumina refineries and to set up new plants (more than 2 Mt/a each). The selection among the bauxite sources is based on previous exploration data, such as: tonnage, grade, mineralogy, etc., the geographical position of the deposit, existing natural and const...

Flow Control in Wells Turbines for Harnessing Maximum Wave Power

Oceans, and particularly waves, offer a huge potential for energy harnessing all over the world. Nevertheless, the performance of current energy converters does not yet allow us to use the wave energy efficiently. However, new control techniques can improve the efficiency of energy converters. In this sense, the plant sensors play a key role within the control scheme, as necessary tools for par...

On Harnessing Natural Resources for Sustainable Development

Is the Present Pace of Economic Development Sustainable? The mainstream economics has characteristically been myopic in visualizing the relationship between human beings and the ecosphere, the surrounding in which they live, work and prosper. Man thought that everything, whether animate or inanimate, exists for him and he exists only for himself. Nature is bountiful to him; moreover, nature is ...
