The strategic overall objective of this project is to produce the highly innovative product in the Solar Thermal market segment, the All Glass Mid Temperature Direct Flow Thermal Solar Vacuum Tube (SOLEGLASS in the future text). That will be achieved by combining the latest cutting edge technology developments in Solar Thermal and Glass industries and the comprehensive and focused research activities to be performed within this project backed with technological integration activities. The SOLEGLASS will enable further development of the innovative types of solar collectors within this project what will ultimately stimulate implementation of enhanced and more efficient Solar Thermal applications for the heat production.Thermal solar market is rapidly growing today in the world at all levels, indifferently whether it is related to the application field or temperature levels. Different application or temperature levels are meeting different complexity issues in product or technology implementation.In this project we are particularly targeting the mid temperature range of thermal solar applications from 100 deg C up to 300 deg C. Mid temperature solar thermal heat generation is combinable with a whole series of power generation, industrial and home applications as:o Industry processes heato Solar Cooling and Heating, residential and serviceo Solar power plantsProducts that we are proposing to develop are designated to the wide population of users which are among others members of the partnering SME-AGs (Croatian Chamber of Economy – CCE, Milan Chamber of Commerce – CCIAAMI and the Asociación Nacional de Fabricantes de Bienes de Equipo – SERCOBE), their national complementary associations and the EU umbrella Solar Thermal associations that are supporting this project.
