A team of researchers from Empa, the Swiss Federal Laboratories for Materials Science and Technology, have designed a new type of electric fan that can lift off the ground and hover, thanks to a spring-powered boost. The device, known as the FanFlyer, works by using a pair of curved blades that spin in opposite directions, much like a helicopter. However, instead of relying on a heavy motor and battery system, the FanFlyer uses a lightweight electric motor that drives a wound spring. When the spring is released, it drives the blades and lifts the device off the ground. The FanFlyer...

Electric fans have become a staple appliance in many households, offices, and other indoor spaces. They provide relief on hot days by circulating air and creating a cool breeze. However, not all fans are created equal. Some fans are designed to be mounted on walls or ceilings, while others are meant to be placed on the floor or a table. One common problem with many fans is that their height cannot be adjusted easily, which can be inconvenient for users who want to customize their airflow. To solve this problem, a convenient mechanism called the electric fan lifting spring has...
