The objective of these new technologies is the radical cost reduction and improvement in the efficiency of coal use which will contribute substantially to more economic, cleaner and environmentally friendly measures for the 'dirtiest' fossil fuel. Having in consideration that potential near future markets for clean coal technologies would mainly be in third countries, the replacement in these countries of old technology coal power plants by advanced ones would extremely help environmental local and global objectives.
The Australian CSIRO Liquatech Hybrid Coal and Gas Turbine System will generate electricity from waste coal and gas that would otherwise have cost money to incinerate and polluted the atmosphere. The method harnesses existing technologies in a 1.2 megawatt hybrid coal and gas turbine system that burns waste coal and methane to generate electricity. A standard three million tonne coal mine produces somewhere around 800,000 tonnes of reject coal. This reject coal is either reburied or is just stockpiled in which case it spontaneously combusts and produces carbon dioxide polluting the atmosphere. The methane is gas of low concentration (about 0.3 percent) which comes out from the ventilation of mines. (Methane is twenty-times more toxic to the atmosphere than standard CO2 so burning it reduces this toxicity by seven times.) One tonne of methane produces three tonnes of CO2 plus the heat which is then used for electricity generation. Methane represents probably about six per cent of Australia's greenhouse emissions.
Since coal is abundant and relatively cheap, and will remain the fuel of choice for many industrializing countries, a collective effort to promote clean coal technologies is essential.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
