Star Wars fans are people who enjoy high fantasy, mythic stories. They like action, drama, romance and teasing out deeper significances to the characters and plot points, relating them to other myths and archetypes in literature. They like technology to be fun and futuristic without needing to understand how it works.
Let's ignore the technologies that might be impossible (e.g. warp drive, dilithium crystals, and transporters). Let's ignore the technologies that we have no idea how to reproduce in a similar way (artificial gravity). Let's just focus on trying to build a space-worthy scale replica of the USS Enterprise that uses existing structural and propulsion capabilities.
Like an increasingly gnarly chia pet, SXSW has exploded in scope at an exponential pace. The massive set of film, music and interactive technology conferences have taken over the city of Austin each year since 1987, so it should come as no surprise that in 2015 yet another joined the fray: the Health & MedTech Expo.
