Spin off of the Polytechnic of Milan in order to create energy from the waves of the sea



The Polytechnic of Milan has introduced the new spin off Techflue Srl dedicated to the ingegnerizzazione, the development and the commercialization of EDS - Energy Double System, a simple, efficient and sustainable device for the generation of electric power from the marine waves. Techflue is participated by the Teze Mechatronics Srl, private incubatore and lucks capitalist inside localized of the industrial pole of the Castellini group Mechanical workshops of Brescia, from the Tecnomac Srl, mechanical Constructions of Brescia, and by Stefano Malavasi, associate university professor of Hydraulics near the Department of Civil engineering and Environmental of the Polytechnic of Milan.

New device EDS, patented and deposited all over the world from the start-up - it has explained the Polytechnic - is installabile near river before the frangimento of the wave also on already existing structures, as for example the docks of the ports, guaranteeing so low costs of assembly. Its yield more is elevated regarding that than similar solutions because it is devised in order to extract the energy of the waves before the frangimento being taken advantage of it is the vertical thrust of the wave (through the movement of a floater "float") is the horizontal thrust of the wave (through the movement of a shovel "paddle"). For the fact to be composed of two different devices, system EDS also is poured them regarding the waves that reach it because in a position to taking advantage of mainly floating or shovel according to the state of the sea that is very variable it is seasonally that daily. The advantage to place itself near the coast facilitates moreover the transport of the released energy and reduces the costs of construction of the structure of support of the system, is if it must be constructed to former-novo and greater reason if existing manufactured products can be taken advantage of. At last - it has emphasized the Milanese athenaeum - system EDS does not need new details technologies in order to work: in fact tax from the waves to a mechanical system is based on the transformation in energy of the movement; this characteristic affords to take advantage of generators already constituents in commerce and therefore a fast development of the system allows.

Al moment the system is tested experimentally and optimized on model small-sized near the Laboratory of Hydraulics "G. Fantoli" of the Polytechnic of Milan. The athenaeum has evidenced that the laboratory data are encouraging being measured advanced yields to 40%, and forecasts of the yield of the installed system assume for a system composed from seven modules EDS that per year occupy 80 meters of coast a annual production that can reach 1 GWh that is translate itself in a saving of co2 in atmosphere of about 100 kilograms every hour, about 1.000 tons.
