Forget about carrying cargo by truck, and instead imagine shuttling goods around inside a series of underground tubes. That's the hope of Henry Liu, a 73-year-old retired civil engineer and a past winner of PopSci's Inventions Awards for his environmentally safe green bricks.
The inventor has received $100,000 as an "encore career" prize from a San Francisco-based organization and plans to use part of the money to push his vision for revolutionizing freight transportation, according to the Columbia Daily Tribune. The network would move boxcar-sized capsules inside underground pipes across long distances, and relies on an electromagnetic pump that Liu invented along with three former colleagues at the University of Missouri.
Liu has founded a company named Freight Pipeline to pursue his transportation idea, so we'll be keeping an interested eye on that. But for now, he can look forward to receiving his $100,000 Purpose Prize from the Civic Ventures think tank at Stanford University this coming weekend.
