The Most Interesting AI Startup This Week Isn't Trying to Replace You
A British ex-DeepMind researcher just raised $50 million to do the least glamorous thing in AI right now: make a new liquid that keeps server racks from cooking themselves. No chatbot. No agent that books your flights. A coolant. And I think it's one of the more honest bets in the whole field. Here's the setup. The AI boom runs on GPUs, and GPUs run hot. Jonathan Godwin, Orbital's CEO, describes a modern GPU rack as packing "basically a supermarket's worth of energy into a filing cabinet." You have to pull that heat out somehow, and one of the best ways the industry found uses a class of chemicals called PFAS. You've heard the other name for them. Forever chemicals. That's the part of this story nobody puts in the funding headline. PFAS don't break down. They show up in roughly 45% of tap water samples tested across the US. They build up in your liver and kidneys over years, and they've been linked to liver damage, thyroid disease, and kidney and testicular cancer. The companies that made these chemicals profitable were rarely the ones drinking the runoff. nihThe Cooling Report So when Orbital says its AI screened hundreds of thousands of candidates to find a coolant that does the job without the forever chemicals, that's not a vanity product. That's pointed straight at a problem that's already in somebody's well water near a chemical plant in North Carolina. Fortune Now the skeptic in me has to speak up, because this field has a track record. Two years back, DeepMind announced its AI had found 2.2 million new crystals, 380,000 of them stable enough to maybe synthesize. Sounded like a new world. Then actual materials scientists opened the database and found over 18,000 of the "discoveries" contained radioactive elements so s
