​If there's one thing that many North American cities need this winter, it's help in snow removal. That's likely why Colorado-based Left Hand Robotics is currently sold out of its SnowBot Pro, which autonomously brushes snow off of sidewalks while avoiding pedestrians.

We once again found ourselves at the annual Colorado Winter Driving Encounter put on by our friends at Rocky Mountain Redline. The event pit eight vehicles from various manufacturers against the snow and elements of Colorado’s high country in the winter. The results were both fun and informative.

​Steel-spiked winter boots may be great on the ice, but on bare concrete or flooring – not so much. It was with this in mind that Canadian entrepreneur Darrell Bachmann created KickSpike boots, which feature spikes that pop in or out of the sole at the kick of a button.

​If you live someplace that gets cold winters, then you'll be familiar with the practise of plugging in your car's engine block heater on frigid nights. Doing so can be difficult, however, plus you may forget to unplug it when driving away. That's where the Q-Plug comes in.

​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.

One of the innovative young brands that really impressed during the recent ISPO Munich show, Advenate has several multipurpose tools for backcountry snow sports. The headliner is an avalanche shovel that includes a probe in its handle and a light, compact emergency shelter in its blade.

We traveled to ISPO Munich to see the latest in European outdoor, action sports and fitness gear and innovation. As usual, the "world's largest sports trade fair" didn't disappoint. Beyond the Swedish electric dirt bikes and Land Rover smartphones, the show had dozens of interesting innovations.

A team of researchers at the University of Alberta in Canada has uncovered an extraordinary new, previously undiscovered, fat-burning mechanism. The new study reveals fat cells just under the skin are sensitive to a specific spectrum of sunlight and shrink when exposed.

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.

​Of the concerns that people have regarding electric cars, one of the most often-heard is that their batteries won't work in cold weather. That may not be an issue in the future, however – scientists have created a new type of electrolyte that allows batteries to work at ultra-cold temperatures.
