  • Fun fact: through the 1800s coal-powered steamships mostly replaced sailing vessels for the transportation of people and time-sensitive cargo around the world. But steamships were highly inefficient and required frequent re-coaling, and locally available coal was dirtier and contained less thermal energy than the good stuff that Britain (who was doing by far most of the shipping) got from Wales and other places on their island. Because steamships could not efficiently and cheaply haul the coal that they needed around the world to restock the coaling stations, this was done instead by an enormous fleet of sailing colliers. So the “steam revolution” of the 1800s was actually a steam/wind-power hybrid. It wasn’t until the advent of triple- and quadruple-expansion steam engines, turbines, and greatly improved boilers in the early 1900s that steam-powered vessels could efficiently and economically haul their own fuel. And even with that, wind-powered cargo vessels remained economically viable and operating in significant numbers right up until the start of WWII (that’s II, not I).











  • My best friend in high school in the '80s had something on his home stereo I’ve never seen before or since: an 8-track tape recorder. We would make 8-track mix tapes and take them to parties … which we promptly got kicked out of because they were tapes of stuff like Yes, King Crimson, Laurie Anderson, Tangerine Dream and Vangelis, and didn’t nobody want to listen to that kind of shit back then.
