When it comes to outlandish transportation ideas, go big or go home

Imagine a future where you tap an app on your smartphone to summon a self-driving car. Heard this one already? Okay, what about when your robot car drives into an airless tube hundreds of miles long and careens across country at close to the speed of sound? Now are you impressed?

Thanks to a gas bubble and a liquid lubricant

The submarine of the future may come to America in a super fast bubble, traveling under water. Researchers at China’s Harbin Institute of Technology developed a new concept for submarine “supercavitation,” where an underwater vessel creates a pocket of air around itself. Inside this bubble, the submarine can travel much faster without friction of water creating drag and slowing it down. Theoretically, a supercavitated vessel using rocket engines could travel inside that air pocket at almost the speed of sound. Continue reading China’s Future Submarine could go the Speed of Sound
