The Spruce Stove in use, prior to being closed around the log

I speak from experience when I say that it's actually fun to go into the woods, saw up fallen trees, then bring the wood home to burn over the winter. What isn't so much fun is subsequently sawing the logs into stove-length pieces. With the Spruce Stove, however, you don't have to – you just continuously feed one long log in as it burns, sort of like feeding a pencil into a pencil sharpener.  Read More

Most bracelets aren't likely to alter your temperature too much either way, but the Wristify isn't most bracelets. Developed by four MIT engineering students, the Wristify works on the principle that heating or cooling the skin on one part of the body can make the entire body feel warmer or colder. By creating a personal heating and cooling device, the Wristify team ultimately hopes to cut the amount of energy currently used to heat or cool entire buildings.  Read More

McLaren’s P1 has already proven itself in Arctic exercises, but more recently it was the job of California, Nevada and Arizona to gang up on the supercar as part of an extreme heat testing scenario. The P1, which McLaren is set to begin delivering in a few weeks, appears to have remained undaunted as temperatures hit record highs of 116ºF (52ºC) during test runs in its new, undisguised finish.  Read More

Researchers have found that a layer of graphene can keep electronic component hotspots up ...

For a two-dimensional material, graphene is certainly punching above its weight in terms of potential applications. Already set to enable faster, stronger and foldable electronic devices, researchers claim that the single layer lattice of carbon atoms can also help keep electronic components up to 25 percent cooler, giving it the potential to significantly extend the working life of computers and other electronic devices.  Read More

Whether it’s through parents’ forgetfulness, ignorance or just plain not caring, it does sometimes happen ... small children die from heatstroke after being left unattended in a hot parked car. According to a 2012 study conducted by the US National Highway Traffic Safety Administration, an average of 38 such deaths occur in the United States alone each year. While various systems have been developed to help keep this from happening, three engineering undergrads from Baltimore’s Johns Hopkins University have taken a unique approach. They’ve converted a Microsoft Kinect into a child-in-the-hot-car detector.  Read More

Splitterwerk Architects and engineering firm Arup have unveiled what is thought to be the world's first building to be powered partly by algae. Officially "unveiled" at the International Building Exhibition hosted in Hamburg, the design, dubbed the BIQ, has a "bio-adaptive" facade that is claimed to be a first for using algae within its glass louvers in order to generate energy, and provide shade, to a working building.  Read More

Apart from heating and cooling the house, water heating is one of the biggest energy drains in the average home. But what if you could literally use cold water to create hot water? That’s just what San Diego inventor Hal Slater claims to have done with the creation of a water heater system that promises to improve water heating efficiency by as much as 50 to 100 percent.  Read More

Some of Fraunhofer's printed thermoelectric generators, wrapped around a sample component

Thermoelectric materials, putting it simply, are able to generate electricity via differences in temperature. If thermoelectric felt were used to make a jacket, for instance, it could generate a current using the temperature gradient between the warm interior and cold exterior of the garment. Like many such promising technologies, however, the cost of thermoelectrics is something of an issue ... although thanks to a new process developed at Germany’s Fraunhofer Institute for Material and Beam Technology, that might not be the case for much longer.  Read More

Kengo Kuma & Associates has designed an experimental house in Hokkaido, Japan called 'Même...

Japanese architectural firm Kengo Kuma & Associates recently demonstrated its ethos of design inspired by light and nature with an experimental house in Hokkaido called "Même." The structure is designed for cold climates and whilst based upon the local Ainu people's “Chise” (House of the Earth), it uses modern materials for an insulated double skin membrane that promotes convection and maintains a comfortable internal environment due to heat circulation from its continually lit fire.  Read More

Both soups and drinks are available in the Hot Can

Last February, the world welcomed its first self-chilling beverage. Of course, a self-chilling beverage was only of so much interest during a time when much of the world's population could just step outside its door and chill its own beverages in the open air – June might have been a better time for that one. What folks could use during the cold season is a beverage container that automatically warms its contents. That container is called the Hot Can.  Read More
