Credit: Kiran Sudarsanan / PPPL Transportation Service Researchers at the US Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have found a way to build powerful magnets that are smaller than ever, helping design and construct machines that can help the world harness the power of the sun to create electricity. without producing the greenhouse gases that contribute to climate change. Scientists have found a way to build high-temperature superconducting magnets made of materials that conduct electricity with little or no resistance at warmer temperatures than before. Such a powerful magnet would fit more easily into the tight spaces inside the spherical tokamak, which is shaped more like a nucleated apple than a conventional donut tokamak, and is being explored as

The bicycle industry seems to be obsessed with 3D printing these days. It has long been a product development staple for rapid prototyping, but is quickly becoming the preferred production method for high-end consumer products as well. Selle Italia and Selle San Marco are jumping into the saddle pool with a new model slated for release later this year, Elastic Interface Technology has incorporated 3D printed pads into a new premium chamois concept, and German outdoor brand Jack Wolfskin is even using 3D printing for backpack pads. What’s next? Only time (and imagination) will tell. Fidlock — maker of all the fancy magnetic helmet buckles, like on Bell’s new Falcon XR — is also continuing to expand its range of magnet-based closures. There are plenty of accessories that use the same hook concept, but also things like a magnet-based hydration bladder reservoir. Perhaps most interesting, however, is the new magnetic ratcheting shoe closure concept called the Winch which is already use
