LOS ANGELES (AP) - Imagine stepping into a car-sized capsule in downtown Los Angeles and, 30 minutes later, emerging in San Francisco.
Billionaire entrepreneur Elon Musk on Monday unveiled a concept for a transport system he says would make the nearly 400-mile trip in half the time it takes an airplane.
If it's ever built.
The "Hyperloop" system would use a large tube. Inside, capsules would float on air, traveling at over 700 miles per hour.
The air would be sucked by a powerful fan at the front and expelled at the rear.
Musk has said he's too busy to oversee the Hyperloop. Instead, he hopes others will take it on.
