Here's a beauty of an eco-innovation from my hometown of Hamburg, Germany.
I've floated the Alster waterways many times, and next time maybe I'll be doing it on a hydrogen-run ferry. They are currently building the fuel-cell powered hybrid Zemship, which stands for Zero Emissions Ship. It will carry 100 passengers around the downtown water passages, an activity reflective of the environmental consciousness of Hamburgers.
Germans are very protective of nature -- they've already got a solar catamaran (seen in the gallery) on the Alster -- so investing in innovations like the Zemship, which will reduce water pollution, is well worth it for citizens.
