From the research of the University of Udine comes an important novelty in the sector of renewable energy and, in particular, in the sector of PV: this is the so-called "Linear Mirror" an innovative solar panel, already in the process of being put into production and commercialized, capable of producing more energy, almost three times more, than photovoltaic modules traditional ones of equal weight and size.
But there's more: having a panel like "Linear Mirror " it will be like having two panels, one photovoltaic and one of type solar for the production of domestic hot water. Linear mirror, in fact, is capable of simultaneously produce electricity e provide heat. The first linear mirror system was presented last Friday, February 26, to the Ocsam mechanical workshops in Basaldella di Campoformido, which helped to build it. And a prototype of a Linear Mirror has already been commissioned by the Friuli Venezia Giulia Region.
Due to its characteristics, the product is intended for private (family and condominium users), public utilities (institutions, schools, hospitals, swimming pools, etc.), industrialists, agricultural enterprises for heating greenhouses, electricity production companies. «The linear mirror - he explains Hans Grassmann, researcher at the University of Udine - makes available, at an affordable cost, a source of clean, efficient energy, suitable for different applications, easy to integrate with pre-existing systems (heating and electrical systems), and with a rapid return of investment. The objective of the “Linear Mirrors” is to offer families and businesses the possibility of using renewable sources without facing a heavy investment such as that required for current solar technologies ».
The linear mirror system is a set of flat aluminum mirrors, from 20 to 50, mounted on a system of axes and levers that tilt the mirrors by means of two small servomotors so as to capture the sun's rays throughout the day on a single receiving surface, similar, in fact, to a single large mirror. The linear mirror, conveying the sun's rays to a collector, is able to heat the water up to about 100 degrees even in winter and to use heat transfer fluids, such as synthetic oils, to achieve temperatures above 200 degrees.
The Linear Mirrors project was born from the research carried out by Hans Grassmann at the Physics Department of the University of Friuli. Patented, it was developed by Isomorph srl (Hans Grassmann, Alessandro Prest), a spin-off company from the University of Udine. Production, industrialization and marketing are handled, in collaboration with the Ocsam workshops in Campoformido, Hans Grassmann, Michele Sambo and Fabio Zilli, who will soon give life to another spin off of the university, Solamente srl. In 2009 Linear Mirrors was ranked second in Start Cup Friuli Venezia Giulia, the regional competition reserved for the best innovative projects.
During the presentation, the President of the Regional Council of the Friuli Venezia Giulia Region, Edouard Ballaman , he declared: «This is an important invention born in one of our universities, that of Udine, which will make renewable sources more accessible for businesses and families. Linear mirrors is a product to be proud of and soon - he announced - a system will be installed on the roof of the Regional Council in Trieste to make our energy saving initiatives even more effective. The Council - concluded Ballaman - will thus be a promoter of savings policies and a springboard for this innovation, born and produced in Friuli Venezia Giulia ».
