Heating

  • Engineers from the University of California San Diego have developed a proof-of-concept armband that can keep the wearer's skin at a constant temperature, even when the ambient temperature is raised or lowered. And the technology is being scaled up to vest size.​
  • ​Squids, octopi and cuttlefish are able to change the color of their skin thanks to specialized cells known as chromatophores. Scientists have now replicated the manner in which those cells work, resulting in a flexible material that can either trap or release heat as needed.
  • A German research team has prototyped an extraordinary heating/cooling system that stresses and unloads nickel-titanium "muscle wires" to create heated and cooled air at twice the efficiency of a heat pump or three times the efficiency of an air conditioner.
  • ​If you're a winter cyclist, then you'll know how off-putting it can be to press your butt down onto an ice-cold saddle. Slovenian inventor Drago Beravs is out to remedy that situation, with his heated Sweet Saddle.
  • If you're dirty and sweaty from performing an outdoor activity, it's understandable that you don't want to drive home that way. Wouldn't it be nice if you could take a hot shower first? Well, the portable Geyser System lets you do so – depending on how you define the word "shower."
  • ​Ravean has been producing different self-heating outdoor accessories for several years now, from vests and hoodies to sleeping bag liners. Now the company is developing a battery-powered heated glove with a recent Kickstarter launch exceeding its goals just days after it went live.
  • For years, the military has been using simple chemical-based heating systems as a way to quickly warm prepackaged rations. Now the YABUL Cook translates such systems into a light-weight silicone device that is foldable and easy to transport.
  • ​Can you control your whole body's temperature by heating or cooling just one small part of it? It seems a little far-fetched, but the makers of the Aircon Watch certainly believe you can, and if their early crowdfunding success in anything to go by, they are far from alone.
  • Keeping safe and comfortable in arctic conditions is a precarious balancing act, so scientists from Stanford University and the US Army Natick Soldier Research, Development & Engineering Center are working on energized fabrics that heat up when powered, yet wick away sweat and dry easily.
  • It can be hard to leave the comfort of a heated home when winter arrives, but humans can't hibernate forever. Fillony wants to make it easier to brave the elements. We've seen heated clothes before, but Fillony thinks it has taken the breed to new places with multi-zone heating.
  • Google’s parent company, Alphabet, has now spawned Dandelion, a new startup that aims to tap into geothermal energy. The company’s signature technology is a geothermal heating and cooling system that pumps heat from the ground into the home in winter, or out of it during summer.
  • ​​It's not just airplane wings that need to stay ice-free in the winter – it's also pretty darn important that the runways not be icy, either. With that in mind, an Iowa State University team has developed a new type of electrically-conductive concrete that melts snow and ice.
