An American filmed his first ride on the German Autobahn and immediately declared it on another level. “Who the fuck has what? Look at this shit,” he shouts as cars fly past, before concluding “dude, this is crazy.” His own caption warns that the Autobahn is not for the weak, and that left-lane drivers had better be pushing 130mph and watching out for pterodactyls. He’s right. The German Autobahn is on another level, and 52,000 likes agree.

What you are looking at is, An electric arc furnace is one of the few machines on Earth that deliberately creates controlled lightning.
Three graphite electrodes, each weighing 1-2 tonnes, carry up to 150,000 amps, generating an electric arc approaching 4,000°C while melting hundreds of tonnes of steel at around 1,650°C.
A single electric arc furnace can pull up to 300 MW of power, enough electricity to power roughly 265,000 homes, yet it concentrates that same energy into a few metres of space to create a controlled 4,000°C electric arc.
The graphite electrodes slowly consume themselves every heat, while hydraulic controls continuously adjust their position to keep the arc stable as the scrap collapses beneath them.
The real engineering challenge isn't creating the heat. It's keeping the furnace alive. Behind the arc sits a lining of MgO-C refractory bricks and water-cooled panels, designed to survive relentless thermal shock, chemical attack from molten slag, and temperatures that would destroy ordinary materials in seconds.
A modern ultra-high-power electric arc furnace costs roughly $50-85 million, while a complete EAF steel plant can exceed $1 billion.
What looks like an old dusty factory with glowing molten steel is actually one of the most advanced industrial systems on Earth, Billion-dollar machines combining extreme electricity, materials science, and automation to produce the steel that powers modern economies.

🚨 LOS ANGELES BANNED FIREWORKS.
Thousands of residents lit them anyway.
Sometimes, governments discover that you can ban an activity...
But you can't ban tradition.
🇺🇸 Happy Independence Day
I love when old items are repurposed or restored. ❤️
This ancient potato peeler has an amazing patina but is only good for decor. To make it useful again, this restoration expert takes his time to bring it back to its former glory. Enjoy the detail and ASMR! 😌
Die Produktion der energieintensiven Industriezweige in Deutschland ist von Februar 2022 bis März 2026 saison- und kalenderbereinigt um 15,2 % gesunken. In der gesamten Industrie ging sie im selben Zeitraum um 9,5 % zurück. Mehr dazu: https://t.co/7qwv7iBLQX

Help an elegant wrinkly sphinx cat swat iridescent bubbles in her gilded clawfoot tub before they float away. Art Nouveau vibes, slow blinks, and a very lunge-y paw.

Three years since the first flight of Starship, the next generation is here. New ship. New booster. New engines. New pad and new test site. SpaceX engineers are working to solve one of the most difficult engineering challenges in history: developing a fully, rapidly reusable rocket
