I recently took a trip to Alcatraz island to see the @Large Ai Weiwei art exhibit.  On the way to the island, I was delighted to find that my ferry was solar-powered!

My excitement was only slightly tempered when the energy dashboard in the cabin showed that the PV output was just enough to power the lights….  The boat is actually diesel-powered, but I won’t stop somebody from doing a good ole green-washing!
