The manufacture of turbines for hydroelectricity has also become a topic. Whether the production of such demanding components is economical will depend to a large extent on production technology equipment. Turbines can successfully use high vacuum for condensation. In this case, due to the large expansion ratio, the discharged gas mixture has a relatively low temperature and can be used by the condenser. Although better fuel and supporting special pumping devices are required, their ultimate economic benefits can fully balance the high cost of the original construction.
