Matt Parker wears a wind turbine t-shirt 🌍

Matt Parker is a popular UK stand-up mathematician with a YouTube channel that covers all sorts of interesting and nerdy subjects. In a recent video (on dithering 2-tone images) he wears a t-shirt emblazoned with 3 colourful wind turbines. With a bit of searching, I tracked this down as being this t-shirt from Rapanui which they note is "Made in a factory powered by wind energy". (There may be some equivocation involved there - they also state "Our products are made from sustainable materials and printed in a renewable energy powered factory" which is not quite the same thing, having a less direct link to the subject matter!) They also have a number of other attractive t-shirts with other wind turbine based designs. There is a dated (from 2019), but still interesting article about Rapanui. (You can see it's dated - they praise Elon Musk as a sustainability shining light; the same Elon who now showers rocket debris polluting areas around his space launches, is destroying our view of the night sky and setting us up for a space junk catastrophe by the huge number of Starlink satellites, and runs huge banks of CO2 producing gas powered generators to power his unsustainable AI ambition, to say nothing of the untold damage his DOGE stint did on environmental matters). As the article says, Rapanui also run the Teemill platform, whereby their sustainable fashion infrastructure can be used by anyone.
