Decks, hulls, interior rooms, engines—when we’re out on the water, we want to be imposing and unmissable, just like in our cars and trucks. Boats are marketed and used primarily in the United States as luxury showcases, leisure centers, and splash-happy racers—that is, for status and pleasure. It’s hard to show off that oceanside yacht, lakeside jet ski, or riverside speedboat if it looks like a speck from the shore. That focus on size, however, has led American boaters to miss out on what may be the industry’s most exciting development over the past decade: the rise of the electric boat. Why exciting? Because electric boats have become a proving ground for some of the most fascinating design and engineering innovations possible. There’s the French-made IZIBoat, a light sailboat that inexperienced water lovers can power with an e-bicycle, as well as the Portuguese recreation company FaroBoats, whose battery-powered models can be quickly recharged by off-grid, floating solar charging docks. Then there’s the Swedish manufacturer Candela’s combination of battery power with hydrofoiling, in which bottom-level attachments lift a vessel’s hulls out of the water in order to increase speed and distance. They also allow the e-boat to run with little in the way of splashes or noise, while ensuring a longer battery life span.

This is the second room-temperature superconductor claim that Kenneth Chang has written about this year. When Sinéad Griffin of Lawrence Berkeley National Laboratory in California had some new findings to share about a seemingly magical material that has made users of Twitter go gaga, she did not have to do much to gain a lot of attention.

Inspired by this, Wanlin Wang at Shenzhen University in China and his colleagues designed a thin film to act similar to energy-saving reflective paints that are already on the market, but which don’t typically offer as many vibrant colours as traditional paints.
