As anyone who knows me knows, I love old technologies (old planes, trains, cars, phonographs, not to mention old irons). So a visit to the Technical Museum is on order. Here is the oldest locomotive (from 1841) in Mainland Europe, another Lilienthal glider, quite a collection of early (circa 1900) electric-powered automobiles and so forth. I will not bother you with the many early airplane pictures I took here, but will include the name of the museum café – Joules Café – that I hope my energy students will appreciate.
