Ma sei proprio sicuro di questa notizia? Si tratterebbe di un
ecomostro senza precedenti (7 Km di diametro alla base) con una
potenza ridottissima (circa 75 MW che con una centrale nucleare si
producono in un reattore di 30 metri di diametro). Tra l'altro il
costo di circa 400 milioni di $ mi sembra un p� scarsino per un' opera
di queste dimensioni. Poi un'opera del genere che ad oggi sarebbe
ancora in fase di pianificazione non penso sarebbe mai pronta per il
2005/2006. Infine gli impatti sul clima locale potrebbero non essere
indifferenti, ma su questo servirebbero degli esperti.
