A self-taught inventor just built a fully functional artificial heart — made entirely from machine parts. ⚙️🫀 No tissue. No silicone. Just pure mechanical precision. Powered by motors, valves, and gears, this device recreates the rhythm of life itself — pumping and circulating fluid like a real human heart. This isn’t sci-fi. It’s a glimpse into a future where machines won’t just support life… they’ll become part of it. Mechanical design meets human purpose. The next chapter of innovation has already begun. 🚀 #technology
