For those who have access to CNBC, there is a really good bit on Elon Musk, Space X, Starship, and the Raptor engine on a recent "Jay Leno's Garage" - season 7, episode 3.
It does a good job of explaining what Elon has planned for the Starship.
Money quote from Elon "I don't care about patents", "patents are for the week".
