As useful as refrigerators and air conditioners are, the gases they use as refrigerants can leak into the atmosphere and become major contributors to climate change. Now engineers at Harvard have demonstrated a new prototype cooling device that uses a … Continue reading Solid-state refrigerant works under pressure for greener cooling
Israeli company Green Kinoko is preparing for the first public tests of a remarkable clean outdoor cooling system. The Kinsho system operates like the inverse of an outdoor cafe heater, cooling several tables per unit without using any electricity.Cont… Continue reading World’s first liquid-nitrogen outdoor cooling system set for trials
Seeing his wife try to use a cool face mask to get through the pain of a migraine headache, [Sparks and Code] started thinking of ways to improve the situation. …read more Continue reading Cool Face Mask Turns Into Over-Engineered Headache
A large percentage of a building’s energy usage is consumed by heating and cooling, but a new dynamic shading system designed by researchers at the University of Toronto could help. Inspired by the skin of krill, the system uses cells of blooming pigme… Continue reading Low-energy fluidic cells could shade and cool buildings dynamically
The UK’s Reaction Engines has started a new test campaign to greatly expand the envelope on its high-mach propulsion technology, hoping to prove it can upgrade current jet engines to be capable of working from takeoff speeds up to Mach 4 and beyond.Con… Continue reading Reaction begins testing Mach 4 jet engine upgrades for US Air Force
The world has been shaken to its core by a respiratory virus pandemic. Humanity has been raiding the toolbox for every possible weapon in the fight, whether that be masks, …read more Continue reading The Benefits of Displacement Ventilation
Although a completely flat-surfaced wheel would be aerodynamic, it would also be hard to keep cool – especially during the braking process. An experimental new wheel rim, however, has cooling vents that open as needed … and they’re activated by heat.Co… Continue reading Active Aero Wheel features brake-heat-activated cooling vents

A huge chunk of energy usage goes towards heating and cooling homes and buildings, so it’s important to find new ways to regulate temperature passively. Engineers in China and Germany have developed a new wood-based foam that can drastically cool build… Continue reading Wood-based foam passively cools buildings to cut energy bills
Thanks to the relatively recent rise of affordable board production services, many of the people reading Hackaday are just now learning the ropes of PCB design. For those still producing …read more Continue reading PCB Thermal Design Hack Gets Hot and Heavy
