I can highly recommend the Deutsches Museum in Munich--great exhibits on German engineering, science, and technology (and a big ol' exhibit of Deckels).

Museum of Science and Industry in Chicago is great.
There are a couple local places in northern CA I want to check out. One is in Santa Rosa--an old sawmill curated (or at least maintained) by our very on Benmychree (John York), and the Knight Foundry in Sutter Creek

+1 on the Henry Ford (great cars and furniture, too) and right next door is Greenfield Village.
Williamsburg is on my bucket list.
Old Sturbridge Village is cool, but more for blacksmithing, and water powered mills.
