"You read that right: The latest bridge design features vertically spinning turbines that would generate an unknown amount of juice while proclaiming loudly that the Portland-Vancouver area is the sustainability center of the world.
Or so says the Florida firm that did the design, now winning the affections of leaders from both cities as well as planners trying to eliminate congestion by building a new $4 billion structure.
It's unknown how much energy the turbines would generate or how it would be used. The turbines might help power bridge lights and toll booths. Or they could be merely decorative icons of a green industry hereabouts --a problem for purists who say that's less than sustainable.
Either way, the concept has captured the imagination of local leaders scrutinizing the project and local architects pushing for a bridge that looks as good as it functions."
