E 'was inaugurated, after only ten years of conflict, that a solar power plant in Priolo Archimedes in the Syracuse area. The plant was celebrated with great pomp in the presence of Environment Minister Prestigiacomo (PDL), which has repeatedly argued the case, and the need to return to nuclear power. But talk of photovoltaics. Finally some good news for the environment. Clean and renewable energy. Only a few small, very small sacrifice. For example, to ground. In fact, the solar field in question made by Enel occupies an area of \u200b\u200b300 hectares. If we think about it is a huge area which results in a terrible waste of resources, first, the ground precisely because asphalt, and then to areas already affected, in Italy we are full. Just think of the motorways, car parks, not counting the thousands of roofs of private houses. Probably the technology thermodynamics is not easy to install on roofs. Yes, because the sun we're talking about is using thermodynamic rows of parabolic mirrors to concentrate the heat of the sun on a pipe where oil flows. In this case, and here is all the vanguard of this Italian plant, molten salts are used instead of the oil produced by the company Angelantoni umbra. Everything suggests a solar pole able to raise Italy from the brink of energy. But I do not think so. Because the power of this poo stuff amounts to 4.96 MW: As two wind turbines not so big. The initial project would produce 50 MW of wonder, perhaps it was discarded because it would otherwise have had to evacuate Sicily. Enel should ask.
The good thing compared to other solar systems is that this mix of salts can be heated to a temperature range from 290 to 550 degrees and therefore operate at night. Enel and Enea talk about a range of eight hours in the dark. The hope is that this has at least the experimental purposes (in theory is so, but expect the practice). Because now the cost is too high for low energy efficiency and the turbine which spins the electrical current is not only powered by steam (because the technology provides thermodynamics that the salts heated to boil water and make steam prodotto faccia girare la turbina) ma anche dal gas di un impianto combinato, diciamo tradizionale. Ma se si migliorasse la tecnologia...
Da aggiungere che Priolo ha già ospitato in passato il più grande polo petrolchimico d'Europa, oggi decadente dopo lo scandalo tangenti Isab del 1973. E' perciò una zona già indicata più volte per ospitare progetti faraonici. Oggi i reperti archeologici, tra i quali necropoli e resti di città greche, si alternano inglobati dalle industrie abbandonate. E' di pochi anni addietro, poi, il progetto, sfumato anche questo per problemi legati al rischio di inquinamento, dell'impianto Recovan che doveva lavorare gli scarti industriali dai quali estrarre il mercurio. In più la Erg sta contrattando with Shell for a regasification plant, one of four under the National Energy Plan to meet the growing gas needs of the peninsula (which receives liquid from Libya after the agreement Berlusconi-Gaddafi). Committees have sprung up, protests that have united to those of an incinerator in the area, in short, is an area where many have tried to build. Finally today the sun, the only completed project. But why here? What did Priolo, which attracts a large number of similar projects?
Meanwhile, someone give us the answer, in Los Angeles have experienced the first panels biological fact used by all the panels are now a derivative of plastic, as is known, is itself un derivato del petrolio. I pannelli bio utilizzano delle alghe al loro interno che attraverso la fotosintesi producono a loro volta idrogeno. Tutto ciò è ancora in via sperimentale ma ha già dato buoni risultati in laboratorio. Certo, è un po' poco direte voi. Ma sempre meglio che sperimentare dopo aver sterilizzato 300 ettari di terreno costiero libero, dico io.
