In Finland, a new generation of energy-efficient data centers is transforming how cities manage heat. Data centers have transformed urban heat management by recovering waste heat from servers and funneling it into the country's extensive district heating networks. This innovative system turns an energy byproduct into a vital resource, significantly reducing reliance on fossil fuels for heating. This ingenious solution addresses two major challenges: the growing energy demands of data storage and urban heating needs. Instead of releasing heat into the environment, Finland’s system recycles it, creating a closed-loop energy network that benefits both technology and society.

These are the brakes responsible for stopping a Bombardier CRJ900, an aircraft that can weigh more than 38 tonnes at takeoff. Unlike the single discs on a car, each main wheel uses a multi-disc brake stack. Hydraulic pistons squeeze alternating rotating and stationary discs together, converting the aircraft's kinetic energy into enormous amounts of heat. At around takeoff speed, a fully loaded CRJ900 carries roughly 100 mega-joules of kinetic energy, with just four main wheel brakes responsible for absorbing a substantial part of it during a rejected takeoff. The real engineering challenge isn't generating enough friction, but surviving the extreme heat. The discs experience repeated extreme heating and cooling cycles, gradually wearing away the friction material. A complete set of four CRJ900 brake assemblies can cost roughly $280,000-300,000 in new brake pads and hardware. If we scale this to the Airbus A380 and it gets even harder to comprehend. At up to 575 tonnes, the world's largest passenger airliner has 16 braked main wheels using carbon brake stacks. Those assemblies represent roughly $2.5-4 million worth of brake hardware. Airlines don't replace all of them together at a fixed number of landings each brake is wear monitored and changed or overhauled individually. At maximum braking, these brakes absorb so much energy in just seconds that the discs can glow red hot, approaching 1,000°C all while bringing hundreds of tonnes of aircraft safely to a stop.

Bubble cavitation is wild because collapsing bubbles briefly create extreme heat, pressure, light, and microjets strong enough to erode metal turning “nothing” (a void in liquid) into a violent energy event. Empty space suddenly becomes explosive physics. Collapse = power.

You obviously have a low iq and don’t understand how guns work. This video proves his body reaction was from a impact from the front 100%. You have a iq under 70 if you think getting shot in the back would push you backwards. You obviously do t understand physics and the kinetic energy of a bullet.

Okay so I made a ScrollController that instead of gestures uses accelerometer (includes gravity!) and basic physics for friction and movement and it’s funny! #Flutter

These 'Beach Animals' were created by Theo Jansen as a fusion of art and engineering. The kinetic structures walk on their own and get all their energy from the wind.
