Remember Rob Rhinehart? I'm sure you do because it's hard to forget about a guy existing solely on vitamin puke. A few months ago we wrote about Soylent, an incredibly nutritious "food replacement" smoothie that Rob, a 24-year-old engineer, had been making and consuming as his only food source for almost five weeks. On one hand, it did look a bit like semen—but on the other, Rob claimed that by drinking it every day he'd never have to eat again. Given that starvation is a fairly major problem in the world at the moment and the planet's population will likely surpass 9 billion by 2050, Rob's invention seems like an important one.
