On the way home from Alaska, I had the chance to briefly visit Dayna and her family, which was great. Dayna was a pro at the "relaxing" pace of touring that I was after, and so we got a really enjoyable *rain free* day to see Tacoma. We took in some Chihuly glass sculptures, in and around the Union Station and glass museum.
Before that we'd wandered north of Tacoma to the site of the famous Tacoma Narrows Bridge, that all of us engineers learned about in school. The bridge was rebuilt (click the link above to see a video of it collapsing), and now, there is a second, parallel bridge to carry the excess traffic.
There's some serious potential for tidal power generation, although I'm told that folks have looked into it and it's not cost effective. Looking down from the train bridge, and watching some seals try and swim towards the ocean (to the right in the photo) was like watching a shrimp on a treadmill.
A quick search shows all kinds of research has gone into Tacoma. Here's a fairly recent news posting:
ReplyDelete"The latest numbers suggest construction costs alone would be almost 50 percent more than the original estimates. Also, the price per kilowatt-hour produced would be 26 or 27 cents, which is three or four times the initial projections, said Scott Amsden, Tacoma Power’s tidal power project manager."
