Just when I was despairing of hard engineering efforts in the 21st century, I picked up this book on my public library’s Overdrive service.  Author Ashlee Vance captures the intellect and drive of this remarkable innovator as Musk disrupts three huge and ponderous industries: space rocketry, automobiles, and solar energy.   This effort after two successful internet startups that left him set for life. Instead of stepping aside to invest in more digital companies, Musk literally went all in with his personal fortune to deliver SpaceX, Tesla, and SolarCity.  His methods are like those of Lockheed’s Skunk Works but absent Lockheed’s deep pockets and defense connections.  His personality is a bit warped and it distorts some personal skills and family life but on balance his achievements far surpass his limitations. Just read it.
