Underrated challenge in war: If you try to maintain equal unit sizes, then bad commanders will receive more resources over time than good commanders. Ukraine solved this for drone teams by creating a marketplace where the currency is video-confirmed kills of Russians.

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. 🎥anshanjusthigh

a message to the haters

"The Pentagon announced they're doing an LCCM buy from Anduril; our Barracuda-500 class. We will produce 7,000 barracudas in 2027. Deliveries on Tomahawks and Patriots are both less than 1,000 a year, so we will make ten times more Barracuda-500s than Patriots or Tomahawks."

London has less aerospace-industrials than LA, but far more AI, tech, and motorsport than LA. London has less AI/tech than San Francisco, but far more NYC style finance and culture. What other city combines aerospace-industrials, frontier AI, finance, and culture? Bull thesis?
