With winter fast approaching, those in the Northern Hemisphere might be looking for some new winter woolies to stave of the cold. But like the teams behind the Avade jersey and Evolve Hoodie, Utah-based Ravean thinks adding some active heating technology to a garment is a better option than resorting to layer and layer. We've spent the past few weeks with Ravean's USB battery-powered heated down vest and heated hoodie and think Ravean and its competitors make a compelling case.
Researchers at the Technological Institute of the Lagoon (ITL), Mexico, have created a nanoparticle-rich, superconducting ink that they have used to coat pipes of solar water heaters to increase their efficiency by up to 70 percent. The new coating was recently proven on the solar heating of a Mexican city sports complex swimming pool, where 2 million cubic meters (70.6 million cubic feet) of water were heated from 26 °C to 37 °C (79 °F to 98°F).
Whether or not you're the type that owns articles of clothing for every reason and season, you may want to make a little extra room within your winter wear collection. One of the latest wearables uses modern tech to keep you more comfortable when it's chilly out. Venture Heat has launched its Evolve Heated Hoodie, a zip-up sweatshirt that's powered by a USB power bank.
It's no secret that the amount and quality of restful sleep has a significant impact on our day-to-day well-being and long-term health. Unlike devices that merely monitor and report sleeping data, such as the Sleepace RestOn, the nuyu Sleep System takes a more active approach under the covers, by automatically changing bed temperature through the night.
While some electric cars may have a decent range in places like
California, they're not so impressive in locations with frigid winters.
That's because their battery is powering not only the motor, but also
the cabin heating system. Now, however, engineers at Germany's
Fraunhofer Institute for Manufacturing Engineering and Automation are
developing new technology that could keep EV drivers warm, without leaving them stranded.
In an effort to improve the energy efficiency of building, researchers have sought to develop windows that change transparency to let more light – and therefore heat – through when it's cold, and less when it's hot. Unfortunately, these methods tend to impede the passage of visible light, some by tinting panes and others by complete obscuration. But a team at the Cockrell School of Engineering at The University of Texas at Austin has developed a "smart window" technology that allows the passage of visible light while blocking heat, or vice versa.
In order to treat injured joints, patients are often advised to apply
heat. This typically takes the form of a hot water bottle or
microwavable hot pack (which are cumbersome and cool off) or a heating
pad (which needs to be plugged in). Now, however, scientists from Korea
and the US have created a battery-powered thin mesh that applies heat
and stays put.
