Venice - Geoaccumulators for heat diffusion, integrated home batteries for accumulating energy produced by renewable sources, electricity diffusion systems and heating systems with heat recovery and energy reuse. These are some of the projects conceived by companies based in the Veneto Region and implemented "in the field" or in university laboratories, and presented in the course of the Astana Expo in Kazakhstan. Tomorrow, in the space dedicated to Veneto in Palazzo Italia, the password will be "sustainable development", expressed through experience and projects. The field experience comes from the Prosecco bio-district, between Conegliano and Valdobbiadene, where producers of the sparkling Docg wine have agreed to privilege renewable energy, from solar panels to pruning biomass and the use of recycled materials in vineyards... in order to manage this prestigious winemaking area sustainably and to respect the environment. In terms of research and innovation, the entity "opening a window onto the future" will be the Levi Cases Centre in the University of Padua, an inter-departmental research hub dedicated to economy and energy techniques, consisting of 240 teachers and 35 study groups, carrying out applied research projects for public and private companies.
