Elon Musk: How the Billionaire CEO of SpaceX and Tesla is shaping our Future - by Ashlee Vance - is a very entertaining biography about Elon Musk (which as the title says, is the biggest drive behind SpaceX and Tesla, and is also involved in SolarCity - all companies with possible huge effects in the world).
The story half reads as a bigger-than-life fictional account of what a genius industrialist goes through to save the world from pollution (with Tesla and SolarCity) and to get us into space.
The fact that it all happened makes it even more interesting.
It also made me really want to get a Tesla. Well, kind of... The triumphs really do, but the listings of problems don't (irrelevant either way as they are not available here)... Less revisions and "free" gas would be great, though. I'd also love to get cheap solar from SolarCity!
Overall, very entertaining, and pretty much recommended for anyone interested in any of the companies.
