Supersonic Electric Jet

What's cooler than an all-electric plane that can fly at supersonic speeds? One that can take off and land vertically.

"I wish somebody would do that," Musk said during a video chat with entrepreneurs. "If somebody doesn't do that, maybe at some point in the future, I will."

At supersonic speeds, an aircraft could go from London to Shanghai in about seven and a half hours. That compares with more than 11 hours for a nonstop commercial flight. An electric plane would have major environmental benefits, and the ability to launch like a rocket would enable airports to eliminate runways and be much smaller, Musk said.
