Fan cooling

Mahle has been hard at work on next-gen e-drive systems, and it's also been exploring other electrification components. It has revealed a thermal management fan that borrows from nature to provide smoother, quieter, more efficient performance.

If you find that you can never get the temperature quite right in bed, a new gizmo called the Homiffi could help. It cranks out either cool or warm air and also acts as a clock, a wireless charger, a Bluetooth speaker and more.

Nobody likes carrying any more gear than necessary when camping ... even if they're just "car camping." Lovork's new Modular Camping Lantern is designed with that fact in mind, as it packs eight functions into one system.

In 2018, we heard how UK startup Volerian was planning to build a VTOL aircraft with a flapping-wing propulsion system. Although we've yet to see a working model, the company has now incorporated the tech into what it claims is a better room fan.

Fans can typically only be locked off or set to oscillate, meaning that they won't necessarily always be blowing on someone who is moving around. As its name implies, however, the Following Fan tracks its user, panning with them as they walk.

​Although it may not be way up there on your list of problems to address, scalding your mouth on too-hot tea or coffee can be a hassle. A German startup is out to do something about it, with the iLIQ temperature-sensing drink-cooling device.

​Riding a motorcycle in very hot weather can be quite vexing, particularly when trapped in traffic-jammed daily commutes. BluArmor Helmets suggests a simple solution to keep the head cool; a detachable air cooler unit that fits to most full-face helmet in seconds and sends refreshing air inside.

Dyson has rolled its air purification, heating and cooling products into one all-powerful air-manipulator. The Dyson Pure Hot+Cool Link can purify the air in rooms and keep them at a comfortable temperature year round, without the need for separate devices.

The GOrb II laptop cooler from Thermaltake blows air up toward the bottom of a notebook to create a cooling gap.

The Bed Fan blows cooling air beneath the sheets of its user's bed.
