🇺🇸 SEAWEED + CEMENT + MACHINE LEARNING = GREEN CONCRETE REVOLUTION Concrete emits nearly its weight in CO₂. That’s 10% of global emissions - baked into every bridge, highway, and skyscraper. Now, a team from the University of Washington and Microsoft just slashed that with algae. Dried seaweed - photosynthetic, carbon-sinking, ocean-grown - replaces part of the cement mix. The result: 21% fewer emissions without sacrificing strength. And instead of waiting years for test data, they used machine learning to find the sweet spot in 28 days. No exotic chemistry. No industrial overhaul. Just bio-materials + AI = fast, scalable, low-carbon infrastructure. Cement built the modern world. Seaweed might help save it.
