Well, turns out he was thinking about the kind of things people usually think about when smoking weed — trippy space planes.
“I have a design for a plane,” Musk said, going on to drop a few details about his latest initiative, an electric airplane that could fly at supersonic speeds and incorporate vertical take-off and landing technology.
”I’ve thought about this quite a lot,” Musk said of his electric aircraft idea. ”The interesting thing about an electric plane is that you want to go as high as possible. You need a certain energy density in the battery pack because you have to overcome gravitational potential energy.”
But a large portion of that gravitational potential energy could be recaptured and harvested on the descent, Musk said. He admitted that, so far, he's only discussed the concept with “friends and girlfriends.” and that he's not particularly focused on the project.
“Electric cars are important, solar energy is important, stationary storage of energy is important,” he said. “These things are much more important than creating electric supersonic VTOL.”

Whatever the intent of his recent public musings, Musk's wobbly behavior appears to be making investors nervous, as evidenced by Friday's decline in Tesla's share price.
Also on Friday, Tesla disclosed that its chief of accounting, Dave Morton, was leaving the company only weeks after being hired.
“Since I joined Tesla on Aug. 6, the level of public attention placed on the company, as well as the pace within the company, have exceeded my expectations,” Morton said on Friday in a statement included in a filling with the US Securities and Exchange Commission. “As a result, this caused me to reconsider my future. I want to be clear that I believe strongly in Tesla, its mission, and its future prospects, and I have no disagreements with Tesla’s leadership or its financial reporting.”
Interesting side note: Rogan credits his appreciation of a marijuana-tobacco mix to Charlie Murphy and Dave Chappelle. That seems relevant, somehow.
